2.3 Administrative Interface
The 780C is equipped with a USB interface. This interface is used to download custom bitmaps and to upgrade
firmware and issue commands. The USB interface is a peripheral device. There are two modes:

COM - Command Mode. Used for sending commands to set the interface, select formats and patterns.

Disk - Mass Storage Mode. Used for downloading bitmaps, audio clips and upgrading firmware or
gateware.
