A.1 General
Remote controls and status information are transferred via an RS-485 (optional RS-232)
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
RFT-1200 never transmits data on the link unless it is commanded to do so.
