Programmer’s Guide

The switcher’s rear panel Remote 9-pin D female connector (figure 4-1) can be connected to the RS-232 or RS-422 serial port output of a host device such as a computer running the HyperTerminal utility, an RS-232 capable PDA, or a control system. This connection makes software control of the switcher possible.

The default protocol is as follows:

• 9600 baud

•

no parity

• 8-bit

• 1 stop bit

•

no flow control

 

NThe MVX 128 A switcher can support either RS-232 or RS-422 serial communication protocol, and can operate at 9600, 19200, 38400, or 115200 baud rates. See Selecting the RS-232/RS-422 protocol and baud rate on page 3-33, Operation, to configure the RS-232/RS-422 port from the front panel.

Host-to-Switcher Instructions

The switcher accepts SIS (Simple Instruction Set) commands through the RS-232/RS-422 port. SIS commands consist of one or more characters per command field. They do not require any special characters to begin or end the command character sequence. Each switcher response to an SIS command ends 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.

Switcher-Initiated Messages

When a local event such as a front panel operation occurs, the switcher responds by sending a message to the host. The switcher-initiated messages are listed below (underlined).

(C) Copyright 2005, Extron Electronics CP 300 450 MAV IP, Vx.xx, 60-799-01]

The switcher initiates the copyright message when it is first powered on. Vx.xx is the firmware version number.

Qik]

The switcher initiates the Qik message when a front panel switching or preset recall operation has occurred.

Sprnn]

The switcher initiates the Spr message when a memory preset has been saved from the front panel. “nn” is the preset number.

Innn Audxx]

The switcher initiates the Aud message when a front panel input audio level change has occurred. “nn” is the input number and “xx” is the dB level.
