Updating Controller Firmware

NOTE: Ensure that the protocol “1K Xmodem” is selected. The “1K
Xmodem” protocol is preferred due to its superior error detection
(CRC vs. checksum).
From the send screen you can monitor the progress of the download. You
can safely stop the transfer without affecting your existing firmware any time
during the transfer until it has been completed. The upload does not
overwrite the firmware during the upload process, it writes the new code into
RAM until completed, then copies the new firmware code to the EEPROM
after verification.
If you elect to stop a download in progress, ensure that the stop (abort)
command was completed by clicking the Cancel button.
Xmodem Send File Screen
