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).
