SIS Programming
and Control
This section describes SIS programming and control of the DMP128, including:
• Connection Options
• Host-to-device Communications
• Command/Response Tables
• Audio level, mix-point, processing blocks, and signal chains
Connection Options
The DMP128 Digital Matrix Processor can be remotely connected via a host computer
or other device (such as a control system) attached to the rear panel RS-232 port or LAN
port, or the front panel USB Config port.
The DMP128 can be set up and controlled using SIS commands, embedded Web pages,
or DSPConfigurator software. See “Installation” on page 5 for pin assignments
and details on the configuration and control port connections. For information on
DSPConfigurator, see “DMP Software” on page 14 and for the embedded Web
pages, see “HTML Operation” on page 137.
SIS commands may be executed using the Extron Electronics DataViewer program, found
on the Software Products DVD included with the product.
DMP128 RS-232 protocol:
• 38400 baud • no parity • 1 stop bit
• 8 data bits • no flow control
NOTE: The rear panel configuration port requires 38400 baud communication. This
is a higher speed than many other Extron products use. The DMP128 control
software automatically sets the connection for the appropriate speed. When using
DataViewer or similar application, make sure the PC or control system connected
to the port is set for 38400 baud.
See “RS-232 Port” on page 114, for additional details on connecting the RS-232 port.
USB port details:
The Extron USB driver must be installed before use (see “Installing the USB Driver” on
page17).
LAN port defaults:
DMP128 IP address: 192.168.254.254
gateway IP address: 0.0.0.0
subnet mask: 255.255.0.0
DHCP: off
