Communication

This section discusses use of SIS commands via RS-232 communication to monitor and get information from the SCP. It contains lists and explanations of the SIS commands that are available for the SCP.

Topics that are covered include:

•• Setting Up RS-232 Communication

•• Communications Between the Host and the SCP

•• Using SIS Commands

•• Using the Switch and Button Table

Setting Up RS-232 Communication

The RS-232 interface allows you to obtain information about the SCP and to activate certain SCP functions from a host computer or other device

(such as a control system\⤀ attached to the rear panel RS-232 port (shown at right\⤀. (For information on wiring this port, see "Wiring the RS-232 Port" on page 10.\⤀

Use the following protocol settings for your computer:

Baud rate: 9600

Data bits: 8

Parity: None

Stop Bits: 1

Flow Control: None

NOTE: For RS-232 communication, DIP

switch #1 must be set to On (up\⤀.

Communications Between the Host and the SCP

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command sequence. When the SCP determines that a command is valid, it executes the command and sends a response to the host device.

Most responses from the panel to the host end with a carriage return and a line feed (CR/LF\⤀, which signals the end of the response character string. A string is one or more characters.
