Product Release 1 Maintaining and Upgrading the Amplifier
Upgrading the firmware on these boards requires a few more simple steps.
The biggest difference with these upgrades is that you must remove the
cover and front panel to access these boards. In addition, you must install
a special cable between the USB/serial board underneath the power-
supply stack and the processor that is being upgraded. You also need a
processor reset cable. You keep your computer connected to the amplifier
via the USB connector on the back of the amplifier and use the same COM
port as before.
