9.7 Updating CW-90/90X Firmware
To update firmware of the CW-90/CW-90X, you must have Revolution installed and a .hex file on your computer.
Visit
www.ricelake.com/manuals to download this free configuration software and the latest .hex file.
JP3 And JP4 Location
Note
If the .hex file is the same version as is currently in the indicator, the firmware update will not reset the
configuration. This is helpful if the firmware becomes corrupt and you want to reload the same firmware.
However, it is always recommended that configuration be backed up in Revolution to avoid any data loss.
1. Unplug power to the CW-90/CW-90X and remove the back plate.
2. Wire the serial cable to the CW-90/CW-90X’s Port 1. Refer to Table 9-6 for cable connection settings.
