Programming Guide

This section describes SIS command control of the DMS matrix switchers, including:

• Local Host-Control Ports

• Ethernet (LAN) Port

• Host-to-Switcher Instructions

• Switcher-Initiated Messages

• Switcher Error Responses

• Using the Command and Response Tables

Local Host-Control Ports

The switchers have two local ports that can be directly connected to a host device such

as a computer running the Extron DataViewer utility or a control system. These ports make

remote control of the switcher possible using a direct connection. The local ports are:

• The rear panel Remote RS-232 / RS-422 port, a serial port on a 9-pin D female

connector (see Remote Port on page 11).

NOTES:

• The rear panel and front panel ports are independent of one another. A front

panel Conﬁguration port connection and a rear panel Remote port connection

can be active at the same time.

• The serial port protocol of the rear panel Remote RS-232 / RS-422 port is:

• 9600 baud • No parity • 8-bit

• No flow control • 1 stop bit

• See Selecting the Rear Panel Remote Port Protocol and Baud Rate, on

page 36 to conﬁgure the rear panel Remote port from the front panel.

• Extron recommends leaving the Remote RS-232 / RS-422 port at 9600 baud

only.

• The front panel Configuration port, a mini USB B port (see Front Panel Configuration

Port on page 13). A standard USB cable and the Extron DataViewer utility, version 2.0

or newer, can be used for connection to the Configuration port.

NOTE: Before you use the Configuration (USB) port for the first time, you need to

install and activate the USB driver on your computer. The simplest way to do this is

to install version 8.0 or newer of the Matrix Switchers Control Program and then run

the Found New Hardware Wizard (see Installing the Software on page 61 and

Activating a USB port for the first time on page 63).
