Connection Options
The DMP64 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 DMP64 can be set up and controlled using SIS commands, embedded web pages, 
or DSPConfigurator software. See Installation on page5 for pin assignments 
and details on the configuration and control port connections. For information on 
DSPConfigurator, see DMPSoftware on page14, and for the embedded web pages, 
see HTML Operation on page120.
SIS commands can be executed using the Extron Electronics DataViewer program, found 
on the Software Products DVD included with the product.
DMP64 RS-232 protocol: 
• 38400 baud • no parity • 1 stop bit
• 8 data bits • no flow contro
NOTE:  Both rear panel configuration ports require 38400 baud communication. This 
is a higher speed than many other Extron products use. When using HyperTerminal 
or a similar application, make sure the PC or control system connected to these 
ports is set for 38400 baud.
For additional details on connecting the RS-232 port, see RS-232 Ports on page93.
USB port details: 
The Extron USB driver must be installed before the USB port can be used (see Install the 
USB Driver on page17).
LAN port defaults: 
DMP64 IP address: 192.168.254.254
gateway IP address: 0.0.0.0
subnet mask:  255.255.0.0
DHCP:  off
