/ System keyboard.
Communication media: In accordance with the interface used.
Baud rate: In accordance with baud rate set in SYSTEM 500M/1000M.
Keyboard address: Make sure the address set is unique.
When used for direct control of telemetry receivers/ICU's:
Keyboard type=
CamCrtl
/ Direct camera control.
Communication media=RS-485.
