Recovering from a firmware upload failure
It is possible to upload DMC firmware with the V
.24 port of a DMC8 card using a PC equipped
with Z-modem protocol. During the upload, the DMC8 card deletes the active and standby
firmware, and stores the uploaded firmware as the active firmware. When the upload
completes, the boot program starts the uploaded firmware.
