RTU-292 Operations Manual

5 Remote Control Protocol

5.1 GENERAL

Included in this section are instructions for controlling the RTU-292 via its RS-232 serial communications port. The protocol listed in this section is the standard command set that accompanies the standard software version. If an RTU-292 is shipped with custom software that employs different commands, a set of special version notes, including a modified protocol, will be shipped with the unit.

5.2RS-232 REMOTE CONTROL OVERVIEW

The RTU-292 may be controlled and monitored remotely via its RS-232 interface. The RS-232 interface consists of RX, TX and Ground only. Hardware and software handshaking are not used. The serial format is 8 data bits, 1 stop bit, and no parity. The baud rate is controlled by setting DIP switches on the CPU card. Available baud rates are 300, 1200, 2400 and 9600.

All commands to the RTU-292 and responses sent from the RTU-292 use standard ASCII characters. All remote commands are terminated with a carriage return (CR) and (optionally) a line feed (LF). Status information returned from the RTU-292 will always be preceded by a "%" character, and is also terminated by a CR. This protocol allows control and monitoring of the RTU-292 via a dumb terminal or a computer program. The commands issued to the RTU- 292 are not case sensitive.

5.3 COMMANDS SENT TO THE RTU-292

The following section describes the operation of each of the RTU-292 remote control commands. All commands have the format:

cmd <data> <data> ... <data> <CR>

The first string is the command string. The command string must not be preceded by any space characters. There is at least one blank (space) character after the command string. Any data that is required by the command follows next. Multiple data sections are delimited by at least one space. Most commands require that data be presented in a specific order. Finally the command is terminated by a Carriage Return character (CR). Line feed characters may be included after the Carriage Return, but they are not necessary.

Examples:

Turn on the Speaker-Radio audio:

SPKR_RAD ON <CR>

Get the firmware revision number:

VER <CR>
