Upgrading the Firmware
Your PC must be connected to the PROGRAM DB-9 to stereo plug connector on the Controller
using the programming cable in order to upgrade the firmware in the ViewPoint. Refer to the Using
Connector Ports section on page 3 for more information on the use of the programming cable.
If power is lost during the download process, the unit powers up with the same set of code it had
prior to the download. There is a small window during which a loss of power can be catastrophic. If
power is lost between the erase of flash memory and the completion of copying the new boot code
from RAM to flash memory, the unit does not operate at all when power returns.
If you have not already installed the SOFTROM program, do so by following the steps contained on
the AMX Control Disc.
