•Look for the illuminated network icon on the front panel or display of each
device:
If the icon is not illuminated, check the cable connection and the LEDs
on the network jack.
If the LEDs are not on and the cable is plugged in, replace the cable and
recheck the LEDs and network icon.
To check connectivity of WWB6 to the network:
1. Start Wireless Workbench software and use Inventory view to see devices
connected to the network.
2. Find the IP address from one of the devices on the network and see if
you can ping it from the computer running Wireless Workbench.
3. From a WINDOWS/MAC command prompt, type ‘ping IPADDRESS’ of
the device (e.g. "ping 192.168.1.100").
4. If the ping returns success (no packet loss), then the computer can see
the device on the network. If the ping returns failure (100% packet loss),
then check the IP address of the computer to ensure it’s on the same
subnet.
5. If the pings are successful and the devices still do not show up in the
WWB6 inventory, check to ensure all firewalls are either disabled or allow
the WWB network traffic to pass to the application. Check that firewall
settings are not blocking network access.

Firmware
Firmware is embedded software in each component that controls functional-
ity. Installing the latest version of firmware updates the receiver to incorporate
additional features and enhancements. New versions of the firmware can be
uploaded and installed using the Firmware Update Manager tool available
in Shure Wireless Workbench 6 (WWB6) software. Software is available for
download from http://www.shure.com.
Firmware Versioning
When updating receiver firmware, update transmitters to the same firmware
version to ensure consistent operation.
The firmware of all devices has the form of MAJOR.MINOR.PATCH (e.g.,
1.2.14). At a minimum, all devices on the network (including transmitters),
must have the same MAJOR and MINOR firmware version numbers (e.g.,
1.2.x).
Updating the Receiver Firmware
CAUTION! Ensure that receiver power and network connections are main-
tained during a firmware update. Do not turn off the receiver until the update
is complete.
1. From Wireless Workbench, open the Firmware Update Manager:
Tools>Firmware Update Manager.
2. Click Check Now to view new versions available for download.
3. Select the updates and click download.
4. Connect the receiver and computer to the same network.
5. Download the latest firmware to the receiver.

Interface Locks
The transmitter and the receiver can be locked to prevent accidental or
unauthorized changes. A locked feature or button will produce the Locked
screen on the LCD panel or the lock icon will flash on a transmitter.
Encryption Mismatch
Re-sync all receivers and transmitters after enabling or disabling encryption.
Firmware Mismatch
Paired transmitters and receivers must have the same firmware version in-
stalled to ensure consistent operation. See Firmware topic for firmware update
procedure.
Radio Frequency (RF)
RF LEDs
If neither blue RF Diversity LED is illuminated, then the receiver is not detect-
ing the presence of a transmitter.
The orange RFSignal Strength LEDs indicate the amount of RF power being
received. This signal could be from the transmitter, or it could be from an
interfering source, such as a television broadcast. If more than two of
the orange RF LEDs are still illuminated while the transmitter is off, then that
channel may be experiencing interference, and you should try a different
channel.
The red RF LED indicates RF overload. Overloads have the potential to
cause interference in multiple system installations. If you are experiencing
an overload, turn off the receiver to see if it is causing interference with other
components.
Compatibility
• Perform a Scan and Sync to ensure the transmitter and receiver are set
to the same group and channel.
• Look at the band label on the transmitter and make sure the receiver is
set to the same band.
Reducing Interference
•Perform a group or channel scan to find the best open frequency. Perform
a sync to transfer the setting to the transmitter.
• For multiple systems, check that all systems are set to channels in the
same group (systems in different bands do not need to be set to the
same group).
• Maintain a line of sight between transmitter and receiver antennas.
•Move or point receiver antennas away from metal objects or other sources
of RF interference (such as LED walls, computers, digital effects, network
switches, network cables and Personal Stereo Monitor (PSM) wireless
systems).
• Eliminate RF overload (see below).
Increasing Range
If the transmitter is more than 6 to 60 m (20 to 200 ft) from the receiver an-
tenna, you may be able to increase range by doing one of the following:
• Reduce interference (see above).
• Increase transmitter RF power level.
• Use Normal mode instead of High Density mode.
• Use an active directional antenna, antenna distribution system, or other
antenna accessory to increase RF range.
Eliminating RF Overload
If you see the red RF LED on a receiver, try the following:
• Reduce the transmitter RF power level
• Move the transmitter further away from the receiver—at least 6 m (20 ft)
• If you are using active antennas, reduce antenna or amplifier gain.
• Use omnidirectional antennas
Antenna Faults
The Antenna Fault red LED indicates a short circuit condition or excessive
load at an antenna port.
• Check antennas and cables for damage
• Ensure that antenna ports are not overloaded
• Check antenna bias voltage setting. Turn off voltage if using passive
antennas.
