  • Transmitter reset: Place transmitters in docks. Press and hold reset button for 5 seconds to restore transmitter factory settings. Transmitter mute LEDs = flashing.

③ Power LED

  • On = Docking station is on
  • Off = Docking station is off

④ Ethernet Port

Connect to an Ethernet network to enable remote device control and monitoring using Wireless Workbench or other control software.

⑤ Power Input

Connect to power supply.

⑥ Battery Status LEDs

Each slot has 5 LEDs that illuminate to show the battery's charge level:

LED % Battery Charge
  • Flashing: <10%
  • Solid: >10%
2 >25%
3 >50%
4 >75%
5 100%

⑦ Docking Slots (USB 3.0)

Slide any ULXD6 or ULXD8 transmitter with a Shure rechargeable battery into a slot to begin charging.

⑧ Ethernet Link Speed LED (Amber)

  • Off = 10 Mbps
  • On = 100 Mbps

⑨ Ethernet Status LED (Green)

  • Off = No network link
  • On = Network link established
  • Flashing = Network link active

Power Connections

  1. Connect power supply to a power outlet and to the docking station power input.
  2. The docking station automatically turns on when connected to power. Press and hold power button to turn off.

If the docking station loses power, transmitters will also power off.

Connecting Transmitters

Insert a ULXD6 or ULXD8 transmitter with Shure rechargeable batteries into the slot as shown:

The docking station provides power to charge transmitter batteries:

  • 15 minutes = 1 hour of use
  • 1 hour = 50% charged
  • 3 hours = 100% charged

Note: If the docking station loses power, transmitters will also power off. Batteries will resume charging when power is restored.

Connecting Shure Devices to Wireless Workbench

Wireless Workbench lets you control and monitor devices over the network. To get started, visit and download Wireless Workbench software. Wireless Workbench communicates with connected devices over a standard Ethernet network.

Required equipment: Shure device, computer with Wireless Workbench installed, Cat 5 (or better) Ethernet cable, and router or network switch

  1. Connect the device to your computer with a shielded Cat 5 (or better) Ethernet cable to ensure reliable network performance. If you have multiple devices to manage, connect each device to a router or network switch. The Ethernet port LEDs on your device will illuminate to indicate network connectivity. Verify that Shure devices can see each other by looking for the network connectivity icon on the front panel (location varies).
  2. For most applications, use the Automatic mode (default) to let your switch or router assign an IP address using DHCP addressing. If no DHCP server is present, your devices will fall back to a link-local address in the range. If you need to assign specific IP addresses, set the IP mode to Manual in the Network menu.
  3. Open Wireless Workbench software.
  4. Select a Network Interface in the pop-up window. Choose the network that most closely matches the Ethernet port where your devices are connected.
  5. Your device will appear in the Inventory tab when the connection is successful.

Configuration Tips

  • Check your firewall settings to make sure Wireless Workbench has access to your network
  • Use multiple Ethernet switches to extend the network for larger installations

Monitoring Batteries with Wireless Workbench

Wireless Workbench provides detailed battery information for each transmitter.

Click the Inventory tab to view the networked docking station in Wireless Workbench.

Each tab provides different battery statistics:


Displays charge as a percentage of the total battery capacity. Also shows time remaining to full charge.


Displays health of selected battery as a percentage of the charge capacity of a new battery. Charge capacity (battery life when fully charged) will decline as a result of repeated charge cycles, age, or storage conditions.


Displays total number of times that the battery has undergone one full count of discharge and charge. Recharging after discharging halfway counts as one half of a cycle. Recharging after discharging a quarter of the way counts as one quarter of a cycle.


Displays battery temperature (in Celsius and Fahrenheit) and status.

Controlling Transmitters with Networked Docking Stations

Quickly review and control many transmitter settings using Wireless Workbench or other external control systems.

You can adjust the following settings:

  • Mute button and mute LED behavior or brightness
  • High-pass filter
  • RF power
  • Power lock
  • Initial state from charger
  • Battery type
  • Device name
  • Channel name
  • Frequency (WWB only)
  • Normal or High-Density Mode
  • Boundary and gooseneck offset

  1. Place transmitters on the docking station. Check that the docking station is connected to the network and to Wireless Workbench.
  2. Find the docking station in the inventory and right-click to select Properties.
  3. Select one or multiple transmitters.
  4. Make changes to transmitter settings and select Apply. Transmitters are now ready to use.

Connecting to an External Control System

SBC450 and SBC850 networked docking stations connect to external control systems such as AMX or Crestron via the Ethernet. Use only one controller per system to avoid messaging conflicts. For a comprehensive list of command strings, visit the ULX-D product page at

  • Connection: Ethernet (TCP/IP; SBC450 or SBC850 is the client)
  • Port: 2202

Firmware Updates

Firmware is embedded software in each component that controls functionality. Periodically, new versions of firmware are developed to incorporate additional features and enhancements. To take advantage of design improvements, download new versions of the firmware using the Shure Update Utility tool.
