6.
At this point all the LEDs will turn off and the “System status LED” will slow pulse orange indicating the
extender is ready to receive the firmware binary file. Under “File” tab use the terminal “transfer”
capability using the XMODEM protocol to initiate the firmware update. Choose “Send” and the firmware
version: cl_ext_device_x_xx.rbf or cl_ext_host_x_xx.rbf, depending on the chosen extender, when x_xx
is the version number.
7.
If no firmware will be sent during 1 minute, or in case of an error the firmware update will fail and return
to previous operation mode.
8.
A successful update will result in appropriate message and a reboot of the extender to new firmware.
9.
Check the firmware version by typing “status” followed by carriage return. Make sure that the firmware
version matches the version on the firmware update package supplied; that would insure the success of
the firmware update operation.

IO Connector
The extender incorporates two RJ45 connectors to provide GPIO functionality such as RS232 and RS422. TTL
and OptoCoupled channels will be available in the future. The pin-out of the connectors can be found in the
