    Methods of avoiding TV stations when coordinating freqs
    Description:

    Overview

    TV stations make up yet another series of obstacles to work around when coordinating frequencies. Depending on your geographic location, you may be heavily impacted by the transmission of one or more TV stations. This page will briefly discuss several methods of avoiding TV stations when performing Frequency Coordination.

    Avoiding TV Channels

    To avoid active TV channels in your vicinity, you might use any of the methods explained in the Creating Exclusions page to block off certain portions of the spectrum from use. In general, however, the most accurate depiction of your RF environment will be captured by running a live scan, and generating exclusions based off of that data.

    The TV database is a static file which calculates your proximity from local TV stations, and blocks out entire TV channels if they are close enough to present an issue. Using the TV Exclusions approach is often overly conservative, as many TV stations are very low power, or blocked by natural/man-made obstructions (mountain ranges, tall buildings, etc) such that they would not present any material interference.

    For this reason, it is recommended to always perform a live scan with a wide-band antenna system placed to optimally cover your area of wireless usage.

    Using the TV Exclusions database is an acceptable fallback plan if accurate scans cannot be taken of the RF environment in whcih you plan to operate your wireless equipment. When scanning is an option, however, there is no need to use TV exclusions. Scan data taken recently from the precise environment in which your gear will operate is the most accurate source of the present RF environment (assuming your hardware and antenna rig is functional and well-tuned).

    This being said, scan data is, by definition, time-dependent. You might take a scan of a venue and see no strong signals, and an hour later, become inundated with broadcast and ENG wireless systems and 2-way intercom communication that clutters your once-clear spectrum. To address this concern, use of the Frequency Plot should be made to constantly scan the spectrum.

    I apologize if this is addressed elsewhere.  I am looking to streamline my wireless setup at the beginning of shows.  I use Wireless Workbench to set up my ULX-D, but I would like to take care of my Sennheiser IEM's as well.  

     

    The problem is the frequency range of my mic's and my IEM's are different, so I cannot use the mic receiver to do the scans for the IEM's.

    I would like to get a dedicated RF scanner that would scan the entire range I need, just looking for ideas; looking at PCR-1000 at the moment.

    The next issue is if/when I get said RF scanner, will WW be able to use it to do the scan, import the results. and automatically set up all my devices, Sennheisers included.

    Thanks for any help....

    AXT610 Access Point with Manual Network Setup?2
    Topic posted January 11, 2012 by Sam DrazinExpert, tagged how-to 
    Title:
    AXT610 Access Point with Manual Network Setup?
    Description:

    Overview

    There are times when a manual network configuration (ie: setting the IP addresses of all networked Shure devices to static values manually) is called for in specific scenarios. Network settings, including IP address and Subnet mask, can be edited easily from the front panel of all rack gear manufactured by Shure.

    The AXT610 ShowLink Access Point, however, does not have a front panel, or an LCD display. Furthermore, the Access Point ships by default in Automatic mode, instructing the device to expect a DHCP server to assign an IP address and Subnet mask.

    This post will cover how to configure your AXT610 with a static IP address and Subnet mask.

    Related Links

    Prerequisites

    In order to configure the IP address and Subnet mask of an AXT610 ShowLink Access Point (currently set to Automatic mode), you will need the following elements:

    • A computer running Wireless Workbench 6
    • Any Axient rack-mounted piece of hardware with PoE (power over ethernet) ports, which include:
    • AXT400 receiver
    • AXT600 Spectrum Manager
    • AXT630 Antenna Distribution Amplifier
    • Or, an AXT900 Charger with an external power supply for your AXT610 Access Point (AXT900 does not have PoE ports)
    • Several ethernet cables

    Configuring the Access Point's Network Settings

    In order to change the network settings of the Access Point, you will need to make a small network of devices that are all configured to Automatic mode. This will enable you to discover the Access Point, and using Wireless Workbench 6, modify the network settings to the desired manual settings.

    Create a Small Automatic Network

    Using the single Axient rack device of your choosing, set the network mode to automatic from the front panel.

    From the front panel of the device, select Util > Network, and then use the control wheel to set the mode to "Automatic". Select the green blinking "Enter" button to confirm the change.

    ad90a0ac6c_01.png

    Then, connect your Access Point to one of the PoE ethernet ports of that device. To the other port of that device, connect your computer running Wireless Workbench 6. This will create a small network of 2 Axient devices, and your computer.

    Launch Wireless Workbench 6. If the proper network configuration on your computer is already set up, you will discover both the rack device (in this example, I am using an AXT400 receiver), and the Access Point, as shown below.

    ad90a0ac6c_02.png

    If you do not discover any devices, open the Preferences menu and navigate to the Network tab. Inspect the network interfaces available to your machine. Also, note the IP address that was assigned to your rack device. You can find this address by going back to the front panel of the device, and selecting Util > Network. The IP address assigned to the device will be displayed.

    ad90a0ac6c_03.png

    Ensure that the IP address of the rack device and the selected network interface of your computer match for every octet of the subnet mask which is "255" by select the proper network interface from within Wireless Workbench 6.

    ad90a0ac6c_04.png

    Note: without a DHCP server present, Axient devices will fallback to a default subnet of 169.254.X.X with a subnet mask of 255.255.0.0. No DCHP server is needed if you can modify your network settings to reach this subnet.

    You should now discover both your Access Point and the rack device in the Inventory view of Wireless Workbench 6.

    If the rack device is shown but not the Access Point, perform a factory reset on the Access Point. Use a fine pencil tip or paperclip to depress the reset button, which is located beneath the power supply connector on one end of the Access Point.

    This will force the device back to an Automatic network mode, which should place it in the default subnet (so long as your computer and the rack device are on this subnet OR a DHCP server is present, all devices will be discovered).

    Once the Access Point is discovered, you are ready to modify its network settings.

    Change the Access Point's Network Settings

    From the Inventory view, right click on the Access Point and select "Properties". The Access Point properties panel will open.

    ad90a0ac6c_05.png

    Expand the "Network" section of the Access Point properties panel. This area will expose the controls to modify the network settings of the Access Point.

    ad90a0ac6c_06.png

    Ensure that the mode is changed to "Manual". The IP address and Subnet mask fields will become editable. Enter the values into the fields to comply with your manual network settings. When complete, press "Apply".

    NOTE: Once you change the network settings of your Access Point, the device will fall offline (unless you changed the static IP address and subnet mask to fit in the same subnet as the current automatic network). The device falls offline because you have changed the network settings to a subnet that cannot communicate with the small automatic network you are currently apart of.

    ad90a0ac6c_07.png

    You will lose control of the Access Point until you reconfigure your manual network and connect the Access Point. Be sure to double check the subnet settings of the Access Point before you press "Apply".

    With a properly configured manual network, you should discover all devices set to their static IP addresses and Subnet masks, including the AXT610 ShowLink Access Point.

    Merging Online and Offline Devices1
    Topic posted November 11, 2011 by Sam DrazinExpert, tagged how-to 
    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.

    Full Band Scan with AXT400 Receiver
    Topic posted November 7, 2011 by Sam DrazinExpert, tagged how-to 
    Title:
    Full Band Scan with AXT400 Receiver
    Description:

    Overview

    The AXT400 receiver is capable of tuning to a bandwidth of roughly 228 MHz. Within this range, a specific band is selected at any given time in which the receiver operates. When scanning, however, the AXT400 can perform a scan across the entirety of its tuning capability. This guide will walk you through the necessary steps to perform a wideband scan using the AXT400.

    Related Links

    Discover an AXT400 on your network

    Launch Wireless Workbench 6, and connect to a network with an AXT400 receiver. You will see the device listed in the Inventory View once discovered.

    5feab05e8d_01.png

    Select the AXT400 as a device to scan

    Navigate to the "Frequency Coordination" tab, and select "Change Scan Data"_" from the right sidebar. This will present the "Scan Data" dialog.

    5feab05e8d_02.png

    Select "Settings"_" to view a full list of online Shure devices that are capable of scanning.

    5feab05e8d_03.png

    Check the channel of the AXT400 that you would like to perform the scan. Then, modify the channel's "Start" and "Stop" frequency values to extend to the wideband edges of the receiver by double clicking and typing the new value in the text area.

    For "Start", enter 470.125 MHz. For "Stop", enter 697.875 MHz. (Note: this is the maximum tuning range of an AXT400 receiver.)

    5feab05e8d_04.png

    Notice that the "Band Preset" field of the modified channel will change to "Custom" instead of whatever band the receiver was tuned to previously. This indicates that the scanning bandwidth is a different range than one of the preset bands.

    Start the scan

    Select "Start". This will begin the wideband scan from the specified "Start" and "Stop" values. The scan data will populate the Frequency Coordination plot.

    5feab05e8d_05.png

    Note that you can modify the scanned frequency range by entering any "Start" and "Stop" values that lie within the bounds of those mentioned above.

    Deleting Backup Frequencies2
    Topic posted November 15, 2011 by Sam DrazinExpert, tagged how-to 
    Title:
    Deleting Backup Frequencies
    Description:

    Overview

    Backup frequencies allow you to coordinate additional frequencies to switch out with your primary devices in the case of RF interference. Backup frequency management is a new feature to Wireless Workbench 6.

    Related Links

    What are Backup Frequencies?

    For a primer on what backup frequencies are and how they can be utilized, read the Adding Backup Frequencies page.

    Access

    Backup frequencies are not displayed in the Inventory view. They are displayed in the Channel Summary dialog. To access this dialog, navigate to the Frequency Coordination tab, and select the "Manage Channels..." button from the top right corner of the right sidebar.

    2e64d2d77f_01.png

    The Channel Summary dialog is where channels are specified to either receive new frequencies, or remain on their current values for the next coordination. It is also where you can manage your backup frequencies.

    Active Devices (items listed in your inventory) are listed in the top portion of the Channel Summary dialog, while backup frequencies are listed in the bottom portion.

    2e64d2d77f_02.png

    Deleting Backup Frequencies

    To delete backup frequencies, simply select them from the list such that the frequency row is outlined with a dotted line, and press the key. You can also right click on any row and select "Delete selected backup frequencies".

    2e64d2d77f_03.png

    The backup frequency will be removed from the Channel Summary dialog, and no longer be a requested frequency for the next coordination.

    Deploying an Existing CFL to a Spectrum Manager
    Topic posted November 7, 2011 by Sam DrazinExpert, tagged how-to 
    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.

    Using the RF History Plot
    Topic posted November 7, 2011 by Sam DrazinExpert, tagged how-to 
    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.

    Monitoring Devices in the Inventory View
    Topic posted November 10, 2011 by Sam DrazinExpert, tagged how-to 
    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.
