REMOTE CONTROL OPERATION
This appendix describes the remote control operation of the RFT-500.
! Firmware number: FW/3059-8-
! Software version:
8.00
Operation of the RFT-500 terminal is normally done from a remote terminal. If you have
ordered the optional keypad, operation at the keypad is described in Chapter 5.
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
RFT-500 never transmits data on the link unless it is commanded to do so.
