A.1 General
Remote controls and status information are transferred via an EIA-485 (optional
EIA-232-C) 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-1225 never transmits data on the link unless it is commanded to do so.
