REMOTE CONTROL OPERATION
This appendix describes the remote control operation of the C5 Satellite Terminal System.
! Firmware number: FW/7414-1-
! Software version:
1.1.1
B.1 General
Remote controls and status information are transferred via an EIA-485 (optional
EIA-232C) serial communications link.
Commands and data are transferred on the remote control communications link as
US ASCII-encoded character strings.
The remote communications link is operated in a half-duplex mode.
Communications on the remote link are initiated by a remote controller or terminal. The
modem never transmits data on the link unless it is commanded to do so.
B.2 Message
Structure
The ASCII character format used requires 11 bits/character:
! 1 start bit
