    Firmware Update UHF-R


    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.

    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.



    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.

      Unfortunately, these UR4Ds and P10T are not visible for WWB6.
      I use fix IP adress, I have established IP connection, via ethernet switch - "0 device online" - sign, at the right bottom in WWB6.
      What do you offer me, resolving this problem ?
      ...Sorry Sam, after the P10 upgrade - it works with WWB6, but UR4D doesn't....

      There is a known issue with Windows 7 machines and the use of fallback IP addressing for both your computer and UHF-R devices. This may be the cause of the problem. Consult the linked post below for more details and recommended workarounds to this issue.

      Known Issue - Win7 Fallback IP Addressing and UHF-Rs

      Thanks Sam,

      Only, I'm wondering a little, because I use XP - OS and not Win7
      So, it means do I use DHCP server and/or change laptop.
      Best regards,

      Hi Imre,

      One other thing to try / verify.... Since you are using "fixed" or manual IP addresses - it is very important that the IP settings of the PC and the UR4s get setup correctly.
      1. Each device / PC must have a unique IP address
      2. Each device / PC must be using the same Subnet Mask

      An example:
      IP Address:
      Subnet Mask:

      UR4 #1:
      IP Address:
      Subnet Mask:

      UR4 #2:
      IP Address:
      Subnet Mask:

      If the subnet mask on your PC is different than the UR4's - then you should set them up to the the same according to your network needs. Then WWB6 should discover the UR4s.

      Hope that helps!

      Thanks Brian, but I have already tested these. Best regards, Imre

      I have one small problem. I'm using OS X Lion and I'd like to work on new Workbench. Although I can't connect my UR4D to Workbench 5 via Ethernet. I installed it in 32-bit mode and everything looks normal, but my program doesn't see any receivers. Moreover I can't open "Configure ethernet connection" button from "devices" bar. After clicking it repeatedly some box pop-up and it says "Shure Control Manager Dialog is already open" but it isn't!
      I need to launch it, because that's the only way to make my firmware update. I hope that you will be able to help me.

      Best regards,

      Hi Michael,

      Did you also connect other devices like PSM1000 transmitters etc. to the WWB6 or only the UR4 receivers? You can't do a firmware update to UR4 recivers via WWB6. You need to update the firmware of the receivers via WWB5 at least up to 1.166 to make them compatible with WWB6.

      If you meant that you couldn't see the UR4 receivers via WWB5, what firmware version of the WWB5 did you install? Most of the WWB5 versions are not comaptible with OSX Lion systems.

      Hi Ron,

      I have a similar situation as Michael. I currently have OSX Lion and have been running WWB 5.0 and wasn't able to update to WWB 5.0.5 because it isn't compatible...any thoughts?

      Hopefully there is some type of fix that doesn't include getting a different computer...


    • hautzir
      Hi Rob,

      It is true that not all WWB5 versions are compatible with OSX Lion. The question is what you want to do with your WWB5 software and why you want to upgrade it to version 5.0.5? Do you want to use WWB5 to upgrade the firmware of your UR4 receivers to make them compatible with WWB6?

      I need to update my UHF-R but my laptop is a Macbook pro with Mountain Lion. Is there a work around for using WB5 to update. Everyone I know that have Macs are on Mountain Lion
    • Gino Sigismondi
      Hi Ryan,

      Unfortunately, updates to WWB5 for Mac never included support for Lion, let alone Mountain Lion. There is no other way to update firmware on UR receivers, other than using WWB5. Perhaps you know someone with a PC that could run WWB5 for you? It doesn't matter which platform you use to update the firmware. I wish I could offer you a workaround, but this is the only option for updating UR firmware.
