Appendix B. Remote Control
This document defines the protocol and command structure for remote control and status monitoring of the RC-
1160/-1260 Redundant Switch Controller.
• Firmware number: FW/3634-1
• Software version: 1.00
B.1 General
Remote controls and status information are transferred via an EIA-485 (optional EIA-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 RC-1160/-1260 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
• 7 information bits
• 1 parity bit
• 2 stop bits
Messages on the remote link fall into the categories of commands and responses.
Commands are messages which are transmitted to the RC-1160/-1260, while responses are messages returned
by the RC-1160/-1260 in response to a command.
