Remote Communication

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 below).

Gnd Rx Tx

J1

3-pole captive screw connector for the RS-232 port on the SCP rear panel

Use the following protocol settings for your PC:

Baud rate: 9600

Data bits: 8

Parity: None

Stop Bits: 1

Flow Control: None

The control device (host) can use the Extron Simple Instruction Set™ (SIS™) commands.

In order to use the RS-232 port, DIP switch 4 must be set to the “on” position.

Using Simple Instruction Set (SIS) Commands

SIS commands can be used with the SCP only when it is in stand-alone mode; that is, DIP switch #4 on the rear panel is in the ON position. The available commands enable you to test the front panel LEDs and buttons, and to query for certain information about the SCP.

You cannot program any SCP buttons or switches using SIS commands. The SCP’s buttons only reflect what is programmed for the System 5 IP to which the SCP is connected.

Host-to-SCP communications

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.

SCP-initiated messages

At power-up, the following SCP-initiated message appears:

© Copyright 2004, Extron Electronics, SCP 150, Vx.xx

This message is displayed only at power-up.

When a local event such as a front panel selection takes place, the SCP responds by sending a message to the host indicating what selection was entered (see Switch responses on page 3-5).

No response to these messages is required from the host.

Error responses

When the SCP receives a valid SIS command, it executes the command and sends a response to the host device. If the SCP is unable to execute the command because the command is invalid or contains invalid parameters, the SCP returns an error response to the host.

Error response codes and their descriptions are shown below. Each error response is followed by a carriage return.

E10 – Invalid command

E13 – Invalid command parameter

E23 – Bad checksum

E28 – Bad filename/File not found

Using the command/response tables

The command/response tables on the following pages list valid command ASCII codes, the SCP’s responses to the host, and a description of the command’s function or the results of executing the command.

The ASCII to HEX conversion table on the next page is for use with the command/response tables.
