Updating the transmitter firmware
If you cannot access the Internet:
Click Browse and navigate to the firmware file you saved.
The software displays the receiver information in list form.
If a newer firmware is available, its version number appears in the Latest
Release drop-down list. In addition, the buttons Update All and Update
become active (see the second table row in the above screen shot). If the
firmware is up-to-date, the text Current is shown instead (see the first
table row in the above screen shot).
To update the firmware of all receivers:
Click the Update All button located above the table.
To update the firmware of individual receivers:
Click Update in the corresponding table row.
A progress bar appears on the receiver display panels while the new firm-
ware is being downloaded and transferred to the receivers via the network.
Then Finalising and a new progress bar appear on the receiver display pan-
els while the firmware is being installed. Finally, the receivers restart. The
table displays the new firmware version and the text Current.
Once you have updated the firmware of all receivers:
Switch on a transmitter. All other transmitters must be switched off during
the firmware update!
The paired receiver automatically detects the differing firmware version of
the transmitter. A message appears on the receiver display panel prompt-
ing you to update the firmware of the transmitter.
Update the transmitter firmware by selecting OK and then confirming by
pressing the jog dial.
The status LED on both the transmitter and the receiver lights up yellow
and Remote Update appears on the transmitter display panel while the

transmitter and the receiver lights up green.
The firmware update was successful.
