Firmware Update
Instructions
Firmware updates are made with Wireless Designer
software and a file downloaded from the web site
and the M2Ra connected via USB. Firmware files are
located at
https://lectrosonics.com/firmware.html
and Wireless Designer software can be downloaded
for Mac or Windows here
wireless-designer.html.
The USB port on the transmitter requires a micro-B
male plug on the connecting cable. The other end
of the cable would normally be a USB A-Type male
connector to fit the most common type of USB jack
used on computers. Our part number for this cable is
21926.
Step 1:
Connect your computer to the M2Ra using the USB cable.
The receiver will automatically power on into Update mode.
Step 2:
Start Wireless Designer and under the "Connect (Live)"
menu, scroll down to Update Firmware, and in the Duet
submenu, click on M2Ra.
Step 3:
Follow the on-screen instructions to choose the update
file, check to see if an update is needed, and initiate the
update process. When finished, check the firmware ver-
sion in Setup>About to verify the update.
