    Title:
    Proper Network Setup
    Description:

    Overview

    Below are some high-level topics which will guide you through successful practices of setting up your network.

    Network Topology

    There are several ways to configure a network of devices. In general, you should always use a "star" network topology where each device uses one connection to an Ethernet switch port. If multiple switches are used, each switch is individually connected to one connection to the next level of Ethernet switch.

    Automatic vs. Manual IP Mode

    Each Shure wireless device on your network has two IP modes:

    • Automatic (or DHCP for UHF-R)
    • Manual

    When in automatic mode, a device expects for a DHCP server to automatically assign it a valid and free IP address. With a DHCP server available (like the AXT620 Network Switch with onboard DHCP server), this makes your life easy. This is also the mode we recommend.

    When in manual mode, a each device must have it's IP address manually set to correspond with all other devices on the network. Some basic rules that need to be followed include:

    • Each device on the network (including computers) must have a unique IP address.
    • All devices on the network (including computers) should share the exact same Subnet mask (this is not always the case, but is a good idea to align)
    • Considering the four octets of a subnet mask:
    • Where the value is 255, that corresponding value of the IP addresses for all devices must be identical
    • Where the value is 0, that corresponding value of the IP addresses for all devices must be unique

    Example:

    Assume all devices on our network have a subnet mask of 255.255.0.0. Because the first two octets of the Subnet mask have the value of 255, the first two octets of all IP addresses for devices on our network must match. Below is a valid set of a few IP addresses for this fictitious network:

    • 200.10.1.10
    • 200.10.4.54
    • 200.10.82.193

    Notice the first two octets of the IP addresses always match, and the last two octets never match.

    Firewall Setup

    In order for Wireless Workbench to discover devices on the network, various portions of the application require network access which may be initially hindered by OS-native or 3rd party security software.

    Configure any firewall or anti-virus software to allow the following processes network access:

    For Macs

    • Wireless Workbench 6.app
    • slpd
    • snetDameon
    • acnproxy

    For Windows

    • WWB6.exe
    • SLPD.exe
    • snetDameon.EXE
    • ShureFirmwareUpgrader.exe
    • snetConfigureexe.exe

    Consult the Wireless Workbench 6 Help System for more information on configuring OS-native Firewall Settings appropriately.

    DHCP Management

    If your network is configured to receive IP addresses automatically (from a DHCP server), there are some basic rules you must follow to ensure proper IP address assignment.

    • All Shure wireless devices must have their IP modes set to Automatic (or DHCP in the case of UHF-R)
    • There must only be one active DHCP server on your network.
    • If you are using multiple switches or routers that have the ability to be DHCP servers, all others (clients) besides the master server must have their DHCP disabled.

    You can verify that your computer is set up to receive automatically assigned IP addresses by checking the DHCP client table on the AXT620 Ethernet switch.

    Check the DHCP server configuration

    Log into the AXT620 Ethernet switch by opening the Internet Explorer web browser to the DHCP server address (default = 192.168.1.1). The default username and password to log in are both "root".

    2a62d10ea2_01.png

    Select the "System' from the main menu, then "DHCP server' option, and finally the "System Configuration' from the middle menu.

    2a62d10ea2_02.png

    The DHCP server switch should be ON and the IP address fields should be set to the above values (as default). If you do not see this configuration and want to restore the factory default, you can select the "Factory Default' option from the main menu.

    NOTE: If you factory reset the DHCP server, you should also power cycle the all other devices on the network after the DHCP server reboots.

    Check the DHCP client table.

    2a62d10ea2_03.png

    Select "DHCP server' from the main menu and then "Client Entries' from the middle menu.

    The DHCP client table should include the computer IP address as well as the IP addresses of all the devices on the net- work. If you do not see the IP address of your computer in the client table, check the DHCP server switch on the front panel to ensure it is set to ON.

    NOTE: You may need to power cycle the DHCP server and computer is the switch was set to OFF and you subsequently turned it to ON.

    Configuring Wi-Fi for Wireless Networking

    When using Wireless Workbench over Wi-Fi, it's important to setup the wireless router properly for best performance. Wireless Workbench employs "multicast" data protocols to communicate to the Axient and PSM1000 devices. Wi-Fi treats broadcast and multicast packets differently than general packets for backward compatibility reasons. In some cases, the Wi-Fi router will limit the multicast packet transmission rate to a value that is too slow for Wireless Workbench to properly operate.

    By default, most Wi-Fi routers are configured to operate in "b/g-mode', which tells the router to allow both 802.11g and older 802.11b devices to operate over the network. In this configuration, some routers will automatically limit the multicast data rates (or sometimes referred to as "basic rate', or "management rate') to 1-2Mbps. For small wireless microphone configurations of less than 20-30 channels, this Wi-Fi setting should not cause any problems with Wireless Workbench. However, for larger wireless microphone configurations of greater than 30 channels, it's recommended to configure the Wi-Fi router to operate in "g-mode' only. Most routers will increase the multicast transmission rate to 6Mbps when operating in "g-mode' thereby providing adequate bandwidth to Wireless Workbench.

    Caution: We have tested Netgear-brand Wi-Fi routers and found that they typically limit the multicast rate to 1-2Mbps even when operating in "g-mode' only, so it's not recommended to use Netgear Wi-Fi routers with Wireless Workbench.

    Scanning the 2.4 GHz Spectrum
    Topic posted November 11, 2011 by Sam DrazinExpert, tagged how-to in Wireless Workbench > All Questions & Answers Topics public
    Title:
    Scanning the 2.4 GHz Spectrum
    Description:

    Overview

    With the AXT610 Wireless Access Point, you can scan the 2.4 GHz spectrum. This will be helpful in diagnosing how your Axient system's ShowLink network will handle in a certain venue, as well as getting a general feel for the RF traffic in that range.

    Related Links

    Required Materials

    In order to scan the 2.4 GHz spectrum, you will need an AXT610 Wireless Access Point. To power the AXT610, it will either need to be connected to an ethernet port that has Power over Ethernet (PoE), or externally powered with it's own power supply.

    ShowLink Plot

    The ShowLink Plot is Wireless Workbench's utility which allows you to scan the 2.4 GHz spectrum, save scans as files, and open old scans to review.

    First, ensure that your AXT610 is online. You will see it populated in the ShowLink Access Point section of the inventory. This is the device that will scan the 2.4 GHz spectrum.

    9b7e885515_01.png

    To access this plot, from the global menu bar, select "ShowLink Plot".

    9b7e885515_02.png

    The ShowLink Plot opens.

    9b7e885515_03.png

    From the left sidebar, select "Add Access Point..." to view all available AXT610s on the network, and check the one you want to use to scan. Press "Save" to add the Access Point as a scanner.

    9b7e885515_04.png

    The Device ID of the Access Point that you added will now show up in the "Access Point:" section in the left sidebar of the ShowLink Plot. This confirms that the device is ready to be used as a scanner.

    9b7e885515_05.png

    To begin the scan of the 2.4 GHz spectrum, ensure that the Device ID of the Access Point is selected in the drop-down of available Access Points. Press "Start" to begin the scan.

    9b7e885515_06.png

    As the Access Point begins to scan, you will see two plot areas populate with data.

    The bottom plot window shows the real-time scan data, marked by the green plot lines.

    9b7e885515_07.png

    The following overlays are displayed and can be toggled by de/selecting them from the Overlays section on the left sidebar:

    • The red overlay represents the Peak Hold of RF levels for the entire length of the scan
    • The yellow overlay represents the average RF levels for the entire length of the scan

    The top section of the plot shows a history of the real-time scans, where time is displayed on the Y (vertical) axis.

    9b7e885515_08.png

    Each pass of the scan adds another horizontal slice to the top of the scrolling scan. Higher energy seen in the spectrum will result in warmer colors being displayed. Use the legend on the top right to gauge how strong of a signal is being seen by the Access Point.

    Other Elements of the Plot

    Notice that there is a wide marker labeled with the Device ID of your online Access Point. This marker indicates your Access Point's channel assignment within the 2.4 GHz spectrum. The channel settings for an Access Point can be configured from the Properties panel of the AXT610.

    9b7e885515_09.png

    There is a zoom bar at the top of the plot as well, which allows you to narrow in on a range of the spectrum to have a closer look with higher resolution.

    A time slider and play/stop controls at the bottom of the plot window allow you to scroll through and progress through the captured scan data.

    9b7e885515_10.png

    Saving a Scan

    Once your scan is complete, press "Stop" on the left sidebar to end the scan.

    9b7e885515_11.png

    The data for your scan currently lives in the active Wireless Workbench session. To save it to a file, right-click on the Device ID of your scanner listed in the top left within the "Access Point:" section, and select "Save...".

    9b7e885515_12.png

    Save your scan file. This file can now be sent via email, or saved to external memory devices and brought to other instances of Wireless Workbench.

    To import a scan file, select the Open folder icon underneath the "Files:" section on the left sidebar. Browse to your file, and select open.

    9b7e885515_13.png

    Once imported, you will be able to view your scan file and browse through each pass of the scan, using the time slider at the bottom of the plot window.

    What is wrong with my network configuration?265.0
    Topic posted November 11, 2011 by Sam DrazinExpert, tagged how-to in Wireless Workbench > All Questions & Answers Topics public
    Title:
    What is wrong with my network configuration?
    Description:

    Overview

    This page will outline a set of tests and diagnostic measures you can run to ensure that your network is properly configured.

    The end-goal is to have a properly configured network such that Wireless Workbench discovers all Shure wireless devices online, and that your computer can effectively and reliably communicate with said devices. This page will act as a troubleshooting guide for debugging your network setup.

    Related Links

    Step 1: Selecting a Network Interface

    Wireless Workbench gives you the flexibility to choose which of your computer's network interfaces you would like to connect to. To inspect or modify which network interface Workbench is currently connected to, go to the Preferences menu and select the Network tab.

    To access the Preferences menu, select Tools -> Preferences.

    69c3c894c5_01.png

    From this display, all available network interfaces known to your computer are displayed. To view more details about a particular network interface, select the "Details" button next to one of the network interface options.

    69c3c894c5_02.png

    Once you have selected the network interface you'd like to use to connect to your devices, select "Save" to commit the change.

    Note: If you have configured your computer for both wired and wireless networking, the two IP addresses must be on separate subnets for WWB to work properly. The wired and wireless adapters on the computer should not be "bridged".

    Network Status Indicator

    Wireless Workbench offers a simple "Network Status" label that, at a cursory glance, allows you to assess the basic state of your connection to a network.

    The Network Status indicator is in the bottom right corner of the application, and is visible in all three tabs.

    69c3c894c5_03.png

    The Network Status indicator can read one of the following states:

    • Network Off: there is no network seen by your computer. If you see this, the network interface you've selected is either invalid, or disabled.

    69c3c894c5_04.png

    • Network On: there is a network seen by your computer, and the label will indicate the number of Shure wireless devices seen online.

    69c3c894c5_05.png

    When you first configure your network of wireless gear, this indicator can serve as a first-check of whether or not your computer sees a valid network or not.

    Step 2: Check your Computer/Hardware

    Pinging devices

    When configuring a network, you may find yourself in the scenario where you are not sure you have a valid connection to a particular networked device. Pinging a device is a precise way to discover whether or not a device is available on the network, regardless of other signs that it may or may not be exhibiting.

    First, isolate the device that you want to ping- you will need to get it's current IP address. On the device's front panel, access the Network menu. For Axient, PSM1000 and UHF-R rack devices, this menu can be accessed by selecting Util -> Network.

    69c3c894c5_06.png

    The device's IP adress will be listed next to the label "IP:".

    69c3c894c5_07.png

    If you are working with a UHF-R receiver, be sure to check the IP address on the left front panel, not the right. This is because the IP address for
    devices in DHCP (Automatic) IP mode is only listed on the left panel.

    Note the device's IP address. For this example, let's use the IP address of the AXT400 receiver above: 169.254.132.186.

    Next, open a command prompt on your computer. For Macs, this would be Terminal. For Windows machines, this would be Command Prompt.

    Type the following command:

    ping 169.254.132.186

    Press return. The results of this command will indicate to you whether your device is online or not.

    The ping command will send a small packet of information the IP address that you listed, and wait for a response. If none was heard, you will see messages similar to this:

    pcni4299al:~ drazins$ ping 169.254.0.1
    PING 169.254.132.186 (169.254.0.1): 56 data bytes
    Request timeout for icmp_seq 0
    Request timeout for icmp_seq 1
    Request timeout for icmp_seq 2
    Request timeout for icmp_seq 3
    ping: sendto: No route to host

    Notice that there was a "Request timeout". This indicates that your computer waited for a response for a certain amount of time, and none came.

    If your ping was successful, you will see a message similar to this:

    pcni4299al:~ drazins$ ping 169.254.132.186
    PING 169.254.132.186 (169.254.132.186): 56 data bytes
    64 bytes from 169.254.132.186: icmp_seq=0 ttl=30 time=0.863 ms
    64 bytes from 169.254.132.186: icmp_seq=1 ttl=30 time=1.086 ms
    64 bytes from 169.254.132.186: icmp_seq=2 ttl=30 time=1.120 ms
    64 bytes from 169.254.132.186: icmp_seq=3 ttl=30 time=1.050 ms
    64 bytes from 169.254.132.186: icmp_seq=4 ttl=30 time=1.088 ms
    64 bytes from 169.254.132.186: icmp_seq=5 ttl=30 time=1.183 ms

    Notice that each line after the PING command reads something like "64 bytes from 169.254.132.186". This is a sign that the device we pinged is on the network.

    If you're still not discovering devices in your inventory after a successful ping, check your firewall settings. Be sure to allow all processes listed in the "Firewall Setup" section of the Proper Network Setup through any and all security and firewall software your computer is running.

    If you ping a device and it does not appear to be connected on the network, some of your next steps should be:

    • ensure that there is a valid network connection from that device to your network (operational ethernet cables/ports, etc)
    • ensure that your computer is connected to the same network as the device you are trying to ping
    • ensure that the device itself is operational

    Common Mistakes

    Below is a listing of common mistakes made when setting up a network.

    • No two devices (including a computer on the network) can ever share identical IP addresses.
    • Ensure that all devices on your network share the same Subnet Mask. Consult the Automatic vs. Manual IP Mode section of this page for more details on proper IP/Subnet Mask configuration practices.
    • Do not connect a device to the same network twice, ie: via ethernet AND Wi-Fi. Connecting a device to the same network interface with two connections will not yield valid results.
    • Ensure that all devices on your network are set to the proper IP mode.
    • Check your ethernet cables and ethernet ports. Replace old cables and look for data transfer indicator lights on ethernet ports with LEDs to indicate such. If these lights are present but not illuminated, this may indicate a faulty or incomplete connection.

    Merging Online and Offline Devices1
    Topic posted November 11, 2011 by Sam DrazinExpert, tagged how-to in Wireless Workbench > All Questions & Answers Topics public
    Title:
    Merging Online and Offline Devices
    Description:

    Overview

    Wireless Workbench allows you to plan out a show's inventory and perform frequency coordination ahead of time. Without access to the hardware in advance, all device settings and frequency values will likely be initialized on offline devices representing your gear.

    When you arrive to the venue, Merging will allow you to take the settings and values from your offline devices and push them to the online devices once discovered in Wireless Workbench.

    Related Links

    Adding Offline Devices

    Initially, you'll want to set up an offline version of your show. This will involve adding all the hardware you expect to coordinate for or around to your Inventory. Select the "Add new device" button from the global menu to access the Add New Device dialog.

    60b348a773_01.png

    From the Add New Device dialog, select the Manufacturer/Model/Band of the device you want to add. You can add multiple devices from this view by selecting a number greater than 1 in the "Active Devices" field.

    60b348a773_02.png

    You can configure select device and channel parameters from this dialog, but this can also be done later from several other views. Once you're ready to add the device(s), select "Add".

    Configure your Offline Inventory

    Once your devices are added in the Inventory view, you can proceed in modifying device parameters and frequency values to your liking. This will often include running Frequency Coordination, calculating compatible frequencies for the devices accounted for.

    For more information on performing Frequency Coordination, refer to the Frequency Coordination tutorial video.

    60b348a773_03.png

    Save your Show File

    A show file is a file that encapsulates all modifiable parameters and devices within your inventory, as well as scan files, show properties, and other elements of your Wireless Workbench environment. Saving your show file will allow you to prepare an entire show's setup ahead of time, and load the show file when you arrive at the venue.

    To save the show file, select File -> Save, or press Command+S for Mac, Control+S for Windows.

    60b348a773_04.png

    Merging your Show File and Online Devices

    Once you arrive at the venue, launch Wireless Workbench and open your show file. To open a show file, select File -> Open, or press Command+O for Mac, Control+O for Windows.

    With your show file loaded, you should see your entire offline inventory set up as you last saved it. You are now ready to connect to your network of Shure wireless hardware.

    Ensure that you have a properly configured network of Shure wireless devices. Connect your computer to the network. If everything is properly configured, you should discover your devices and they will be displayed in the Inventory view alongside your offline pre-configured devices.

    60b348a773_05.png

    We want to take the parameters from the offline devices and apply them to the online devices. This can be accomplished simply by dragging and dropping the offline device on-top of the online device.

    60b348a773_06.png

    This tells Wireless Workbench that you want to merge the offline and online versions of the device into a single entry.

    NOTE: Merges are only allowed if the following criteria are met:

    • Both devices of the same model and band
    • One of the devices is offline, and the other device is online

    The yellow border around the destination device indicates that a merge is allowed to occur. If that yellow border does not show up, then you have not met the 2 requirements needed to perform a valid merge.

    In order to allow you to specify which parameters you want to keep (either offline from the show file, or online from the live devices), the Device Association dialog is displayed.

    60b348a773_07.png

    To briefly summarize this dialog's functionality, the toggle buttons shown allow you to specify the source of the parameters that will be kept for the devices in merge. Choose to keep offline or live settings for both the Frequency parameters and Settings parameters for each device you want to merge.

    To keep the settings we set on the offline device and overwrite the hardware's current settings, we'll select "From OFF-LINE Device" for both Frequency and Settings buckets of parameters.

    60b348a773_08.png

    Select "Apply" to apply the merge.

    For more detailed information on the specifics of how to use the Device Association dialog, consult the Device Association Dialog page.

    After the Merge

    Once the merge is complete, notice that the old offline version has gone away, and the online version of the device now has all the parameters that were set on the offline version. Awesome!

    60b348a773_09.png

    Continue to drag-and-drop offline and online devices to merge until all offline versions of the devices have passed their parameters to their online counterparts.

    Monitoring Devices in the Inventory View
    Topic posted November 10, 2011 by Sam DrazinExpert, tagged how-to in Wireless Workbench > All Questions & Answers Topics public
    Title:
    Monitoring Devices in the Inventory View
    Description:

    Overview

    The Inventory view portrays a live list of all discovered Shure wireless gear, as well as any offline devices. This view can be used to organize and configure settings for both online and offline devices, as well as a number of other actions.

    Related Links

    Sort and Organize

    The Inventory view allows you to sort and organize your devices in a variety of ways.

    Set your sort order by one of three options:

    • By Header (column headers show in Inventory view, like Model, Channel Name, Device ID, etc)
    • By Type (Device Type, like Microphone, In Ear Monitor, Intercom, etc)
    • By Zone (Zones that you've allocated and organized your devices into. For more information, consult the How do I create and utilize zones? topic)

    657326b09b_01.png

    Filter

    You can also filter what devices are shown in the Inventory view. Use the sidebar on the right to display a subset of all the devices in your inventory. You can sort by a mixture of the following criteria:

    • Search term (freely typed)
    • By Tags (user-created tags assignable to all devices)
    • By Type (Device Type, like Microphone, In Ear Monitor, Intercom, etc)
    • By Manufacturer (useful when incorporating non-Shure gear)
    • By Zone (Zones that you've allocated and organized your devices into. For more information, consult the How do I create and utilize zones? topic)

    657326b09b_02.png

    Device Discovery

    With a properly configured network, all networked Shure devices on your network should be discovered by Wireless Workbench and shown in this view.

    Online devices will appear with black text, and fully colored icons.

    657326b09b_03.png

    To match a device in the Inventory view with its physical counterpart, right-click on the device and select "Flash". The front panel LEDs and display of the actual rack device will flash. (Tip: clicking on a device's icon on the far left will also flash the device).

    657326b09b_04.png

    Offline Devices

    Offline devices act as placeholders for either online devices that are currently unavailable, or non-networked devices for which Wireless Workbench will analyze/coordinate frequencies.

    Offline devices will appear with gray text, and off-colored icons

    657326b09b_05.png

    Any devices added through the Add New Device dialog will also show up in the Inventory view as an offline device.

    Likewise, devices imported from a show file or inventory file that are not merged with devices currently online will show up as offline devices.

    Modifying Device Parameters

    Editable device parameters for online and offline devices can be modified from the Inventory view. To change an editable parameter (for example, for example Frequency), double click on the frequency field of a given channel. Either type a new value of the frequency, or choose a value from the drop down.

    657326b09b_06.png

    If you are editing an online device, the changes made will immediately be pushed to the hardware.

    Enable the System Logger and Access Log Files
    Topic posted November 10, 2011 by Sam DrazinExpert, tagged how-to in Wireless Workbench > All Questions & Answers Topics public
    Title:
    Enable the System Logger and Access Log Files
    Description:

    Overview

    Wireless Workbench has a System Logger built into the application. If enabled, this logger will run in the background and keep track of any issues that the application runs into. Log files generated by this logger are extremely helpful to our development team in diagnosing a problematic scenario, if one should arise.

    The logger is disabled by default.

    Related Links

    Access

    To access the System Logger's menu, launch Wireless Workbench 6. Hold the Shift key down, and click on the Tools menu. You will notice that a new menu appears (called "Diagnostics"). Within this Diagnostics menu, select "Setup Logger".

    8799b3e2da_01.png

    The Logger Setup dialog will be displayed.

    8799b3e2da_02.png

    This dialog hosts all available controls to enable and customize how the logger functions.

    To enable the logger, check the check box "Enable Logging Capability".

    8799b3e2da_03.png

    There are many other preferences that you may want to set which will control how the logger captures system data. In general, leaving all controls in their default state will record the maximum amount of information available, which is ideal.

    To access the log files, notice the path listed in the field next to "Folder:".

    8799b3e2da_04.png

    This is where your log files will be saved automatically. You can change this destination path by using the "..." browse button and selecting a new path.

    Clean Up Old Log Files

    To get rid of old log files that may no longer be useful, use the controls in the bottom of the Logger Setup dialog.

    8799b3e2da_05.png

    To remove files created before a certain date/time, select the "Before" radio button, and enter the date/time that you'd like to be the threshold. All log files created before this threshold will be deleted. Select "Start Clean Up".

    Title:
    How do I create and utilize zones?
    Description:

    Overview - What is a "Zone"

    If you are setting up wireless devices in a large space, such as a campus with multiple rooms, you may be able to divide the environment into zones and increase the number of frequencies available.

    To maximize the number of frequencies available for larger venues such as corporate campuses, festival venues, and theaters, you may be able to divide the environment into zones. Creating zones in Wireless Workbench tells the frequency compatibility calculator to assume that systems in one zone will not create intermodulation distortion with systems in another zone.

    The key is to place the devices in different zones and provide enough RF separation between each zone to prevent intermodulation distortion (IMD). Factors that must be considered when creating zones are the physical distance between zones, occlusion by building materials, the volume of surrounding RF traffic, transmitter output power, antenna selection and placement, and overall quality of the wireless system.

    Ideally, devices assigned to separate zones should be physically separated by walls. Other factors that must be considered when creating zones are volume of surrounding RF traffic, transmitter output power, antenna placement, and overall quality of the wireless system.

    Zones and Intermodulation Products

    When multiple zones are present, Wireless Workbench will calculate a multi-zone compatible frequency list. When you create multiple zones, you are telling Wireless Workbench the equipment is far enough apart to avoid creating intermodulation products. Calculating compatible frequencies for zones with Wireless Workbench will ensure a solution with no channel-to-channel conflicts.

    Assigning Equipment to Zones

    A device cannot be in multiple zones. This means that a receiver with multiple channels must all use channels within the same zone. Additionally, any linked transmitter and receiver pairs must be within the same zone.

    Zones and Spectrum Managers

    Each zone created in Wireless Workbench requires an AXT600 Spectrum Manager to deploy frequencies to the equipment assigned to that zone. When Workbench calculates a frequency list, it will use the zone information to create and deploy a frequency solution to each zone.

    Saving Zones Across Sessions

    The zone parameter is not stored on devices. To save the zones in Wireless Workbench, you must save your show file. Otherwise, when the equipment goes offline and then comes back live on the network, all equipment will be shown in the same zone.

    Creating a Zone in Wireless Workbench

    Zones can be created in Wireless Workbench from several locations in the application. First, we'll discuss creating zones from the Add New Device dialog.

    While populating your inventory with offline devices and backups, you can specify to add these channels to specific zones. To choose from existing zones, this is done by selecting a particular value from the Zone drop-down in the Device Properties section.

    8d541349be_01.png

    You can also create new zone by selecting the "Edit Zone..." drop-down and choosing "New Zone."

    8d541349be_02.png

    The New Zone dialog will prompt you to name a new zone, which can then be used to contain devices.

    8d541349be_03.png

    Zones can also be created and assigned from the Inventory tab. In the right sidebar of the Inventory tab, the bottom section, entitled "By Zone", shows a list of all available zones. The check boxes next to each zone allow you to filter your inventory by zone assignment.

    To create a zone from this view, right-click within the By Zone box, and select "New...". The New Zone dialog prompts you to name a new zone.

    8d541349be_04.png

    Make sure the Zone column is displayed to easily view and edit the zone of a given device from the Inventory view. Right-click in the header section of the inventory view, and ensure that "Zone" is checked.

    8d541349be_05.png

    To assign devices to a zone from the Inventory view, you can do one of several actions:

    • Drag and drop the zone from the sidebar area on to the Zone area of a device's row.

    8d541349be_06.png

    • Double click the Zone area of a device's row to select its zone from a drop-down of all available zones

    8d541349be_07.png

    Assigning Spectrum Managers to Zones

    Once your zones are created and devices are assigned to the zones of your liking, you can begin to take advantage of the efficiencies that come with zone coordination.

    If you have one or more Spectrum Managers, frequencies can be deployed to them such that they constantly monitor backup frequencies for those devices. This is configured after calculation in the RF Coordination Results dialog.

    For full details on Frequency Coordination and how to navigate the workflow, consult the Frequency Coordination tutorial video.

    After a solution has been calculated, you will have the opportunity to assign each zone a Spectrum Manager, assuming each zone has a Spectrum Manager within it (Spectrum Managers are assigned to zones in the Inventory view, as described above).

    At the top of the summary section of the RF Coordination Results dialog, a table of all zones is displayed.

    8d541349be_08.png

    Each zone can be assigned one of two options:

    • A valid Spectrum Manager within it's zone that is not managing another zone
    • "None"

    When you select a specific Spectrum Manager for a given zone, upon deployment, all of that zone's frequencies will be sent to the Spectrum Manager, and it will monitor those frequencies in real time.

    When you select "None", Wireless Workbench will keep a list of all frequencies deployed to that zone, but no live monitoring of the quality of those frequencies will be performed.

    Viewing Deployed Frequencies

    Frequency lists for all zones, regardless of where they were deployed to (Spectrum Manager or Wireless Workbench, eg: "None") can be viewed post-deployment in the Frequency List window.

    From the global menu bar, select "Frequency List".

    8d541349be_09.png

    This will show a full listing of all deployed frequencies for each established zone. Zones with managing Spectrum Managers will show updating strengths of frequencies within their lists.

    Firmware Update UHF-R24
    Topic posted November 8, 2011 by Sam DrazinExpert, tagged how-to in Wireless Workbench > All Questions & Answers Topics public
    Title:
    Firmware Update UHF-R
    Description:

    Overview

    In order for Wireless Workbench 6 to work with UHF-R wireless receivers, the firmware of those devices must be updated to firmware version 1.166 or later. The following article will explain how to firmware upgrade UHF-R receivers.

    Related Links

    Check UR4 Current Firmware Version

    To check which version of firmware your UHF-R receiver is currently running, power-cycle the rack device, and pay attention to the front panel display as it boots up. The installed version of firmware will be displayed in the lower right-hand corner of each display. If the version is 1.166 or later, your receiver is compatible to operate with Wireless Workbench 6.

    Updating Firmware

    If your receivers are on a version of firmware earlier than 1.166, they will need to be updated in order to be discovered and controlled by Wireless Workbench 6.

    In order to upgrade the firmware for UHF-R receivers, you can now use the Shure Update Utility (v2.0.2 or later). Follow the steps listed out below to complete the firmware upgrade.

     

    1. If you do not have the Shure Update Utility, you can download it here.

    2. Power on your UHF-R receivers. Connect your network of receivers to your computer, and launch the Shure Update Utility.

    Note: UHF-R receivers will not appear as online devices within Wireless Workbench while the Shure Update Utility is running.  Once the Shure Update Utility is closed, the UHF-R devices will reappear as online devices in Wireless Workbench 6.

    3. Select "Check for Updates".

    4. Download any available updates.

    5. Once the downloads have completed, select the "Update Devices" tab and ensure that your UHF-R receivers are discovered.

    6. For each UHF-R receiver to be updated, select the checkbox on the far right of it's row, and then select the desired version to install in the "Version to Install" column.

    7. To begin the firmware update, select "Send Updates".

    Do not power off or disconnect your device from the network while the firmware update is in process.

    8. Once the update has been sent, your device will reboot.  The Shure Update Utility will wait for the receivers to be rediscovered and verify that the sent firmware was properly installed.

     

    Transmitters

    The UHF-R transmitters were designed to be forwards compatible with newer versions of UHF-R receiver firmware. It will likely not be necessary to upgrade the firmware of your UHF-R transmitters. NOTE: this implies that differing firmware versions between UHF-R transmitters and receivers is an acceptable mis-match of firmware versioning.

    If you have any questions, please contact Shure Service and Repairs.

    Using the RF History Plot
    Topic posted November 7, 2011 by Sam DrazinExpert, tagged how-to in Wireless Workbench > All Questions & Answers Topics public
    Title:
    Using the RF History Plot
    Description:

    Overview

    The RF History plot is a plotting tool which allows you to track the RF strength of numerous channels over time. Wireless microphone receivers are used to scan the strength of their associated transmitters during RF transmission.

    This functionality can be used to perform walk tests to discover the signal strength a transmitter will have as it travels throughout a venue. You can also perform a distance test of your transmitter/venue, measuring how far out the transmitter can travel fromt he receiver while still passing an audible signal.

    NOTE: Using the RF History plot does not impede the audio signal chain in any way. This plot can be run while the transmitters are in-use.

    Related Links

    Access

    Launch WWB6, and from the top menu bar, select "RF History Plot".

    80eadf2810_01.png

    From the left sidebar, select "Add Channels".

    80eadf2810_02.png

    The "Add Channels" dialog opens. From this dialog, check any and all channels that you want to add to the plot. This window is effectively the same as the selection window from WWB5 (shown on right).

    80eadf2810_03.png

    Select "Save", and then ensure that the channels you added show up in the "Channels:" area of the left sidebar of the RF History Plot window.

    80eadf2810_04.png

    To begin scanning, select "Start". (Checking the "Enable Autologging" check-box will also begin scanning).

    80eadf2810_05.png

    Scan data is shown on the plot area. Scans from transmitters will be displayed when the channel is selected and highlighted green on the left sidebar.

    80eadf2810_06.png

    Once you have begun scans, you can close the RF History Plot dialog. It will continue to scan RF levels from your transmitters until you stop it.

    To save a scan from this plot, right click on one of the channels listed on the left side bar in "Channels:" area, and select "Save"_".

    80eadf2810_07.png

    NOTE: there is a hard maximum of 20 transmitters that the software can scan concurrently. This is a limitation that was put in place to ensure overall stability of the plotting, as well as the rest of the application.

    Deploying an Existing CFL to a Spectrum Manager
    Topic posted November 7, 2011 by Sam DrazinExpert, tagged how-to in Wireless Workbench > All Questions & Answers Topics public
    Title:
    Deploying an Existing CFL to a Spectrum Manager
    Description:

    Pre-conditions

    It is assumed that a compatible frequency list (or CFL) was calculated offline while not connected to any gear. When connecting to the gear, ensure that the Spectrum Manager(s) and all subordinate devices are discovered in the Inventory View.

    Related Links

    Deployment and the CFL

    Currently, the CFL that was calculated offline lives inside Wireless Workbench, and will be saved with a show file. To send out a CFL to a Spectrum Manager, a deployment must be performed. This is the case when deploying an existing CFL, or a brand new one as a result of coordination.

    The Spectrum Manager retains a CFL through a power cycle. If this is not the first time you are using your Spectrum Manager, it is likely that there will already be a CFL stored in its memory. You must delete the currently stored CFL from the Spectrum Manager in order to not merge old (and potentially incompatible) frequencies with your CFL.

    A quick way to verify whether or not your Spectrum Manager has a CFL is to discover the device (so that it shows up in the inventory view), and open the Frequency List window. Select the "Frequency List" button from the global menu bar to access this window.

    e7db748768_01.png

    You should see two columns of data in the Frequency List window. One of the columns will represent the deployment and frequency list hosted by Wireless Workbench; this will be the one with the Spectrum Manager value listed as "None" at the top of the column.

    e7db748768_02.png

    The column on the left in the image above shows the CFL that was already in the Spectrum Manager when it was discovered. You can also tell that this section of the Frequency List window is managed by a Spectrum Manager, as the backups list has colored LEDs and dBm values that live update as the frequencies are being monitored (this functionality will only be available when a Spectrum Manager is present).

    In order to get our known and trusted CFL into the Spectrum Manager, we will clear the device's currently hosted CFL.

    Note that both Frequency Lists (one hosted by Workbench, and one hosted by the Spectrum Manager) belong to the zone "Default". Deleting the CFL from the Spectrum Manager will begin the process to consolidate these two into a single Frequency List.

    Clear a Spectrum Manager's Current CFL

    From the home screen on the right side of the Spectrum Manager, press "CFL".

    e7db748768_03.png

    Select "More".

    e7db748768_04.png

    Select "Clear" to erase the CFL from the Spectrum Manager.

    e7db748768_05.png

    Press the green blinking "Enter" button to confirm.

    e7db748768_06.png

    You will see the message "No Compatible Frequency List" when the CFL has been successfully erased.

    e7db748768_07.png

    To confirm that the Spectrum Manager does not have a CFL, go back to Wireless Workbench and inspect the Frequency List window. You should see that the column of frequencies managed by the Spectrum Manager is now empty affirming the fact that the old CFL hosted on the Spectrum Manager has been destroyed.

    e7db748768_08.png

    Deselect all channels so they remain on their current frequencies

    Go to the Frequency Coordination tab, and select "Manage Channels"_" from the right sidebar. The Channel Summary dialog will open.

    Press the Select: "None" button to uncheck all devices. This will ensure that all devices stay on their current frequencies.

    Before you close this dialog, be sure to press "Refresh Live Backup List". This button will keep your list of backup frequencies is in sync with the current state of the hardware/backup list.

    e7db748768_09.png

    Select "OK" to confirm.

    From the right sidebar of the Frequency Coordination tab, select "Calculate New Frequencies" to initiate the coordination, which we just configured to not calculate any new frequencies.

    e7db748768_10.png

    The summary on the RF Coordination Results will indicate this as well, showing that zero frequencies were calculated for devices as well as backups. After this null calculation, we can now configure Wireless Workbench to deploy our known frequency list to the Spectrum Manager.

    Spectrum Manager assignment for each zone

    Ensure that each zone with devices assigned to it has its corresponding Spectrum Manager. This assignment is made by selecting the appropriate Spectrum Manager for each zone from the drop-down at the top of the "Summary" section.

    e7db748768_11.png

    This is how Wireless Workbench will know which Spectrum Manager should receive each CFL. Note that the associated Spectrum Manager must also be in the same zone as the devices it will manage.

    By selecting "None" for a given zone, Wireless Workbench will internalize that CFL, and save it within a show file. This is how offline results can be saved without access to a Spectrum Manager.

    NOTE: Only one Spectrum Manager can manage a zone and it's CFL at a given time. This means you will need one Spectrum Manager per zone for which you would like backup monitoring and automatic frequency dispatching to AXT400 receivers.

    Sending out the CFL

    Press "Deploy to Inventory" to send the CFL to the designated Spectrum Manager.

    e7db748768_12.png

    To confirm that the Spectrum Manager has received the CFL, go to the device's front panel and select CFL -> Edit to display the Spectrum Manager's full CFL. Check this list to ensure that all frequencies that were a part of your frequency list were transferred.

    Another way to confirm that the Spectrum Manager has received the desired CFL is to open the Frequency List window. You will notice that there are no longer 2 columns, but instead, one with the CFL from your past coordination. Also, that CFL will have a Spectrum Manager assigned to it, and listed at the top of the column.
