Connection Options
The DMP 44 LC 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 the front
panel USB Config port.
The DMP 44 LC can be set up and controlled using the Extron SIS (Simple Instruction Set)
commands or DSP Configurator software. See the “
Rear Panel Features and Cabling
”
section for pin assignments and details on the configuration and control port connections.
For information on DSP Configurator see “
SIS commands may be executed using the Extron Electronics DataViewer program, which
may be found on the Software Products DVD included with the product.
DMP 44 LC RS-232 protocol:
• 38400 baud
• no parity
• 8 data bits
• no flow control
• 1 stop bit
NOTE: The rear panel configuration port supports 38400 baud communication. This
is a higher speed than that of many other Extron Electronics products. If using
HyperTerminal or a similar application, make sure the PC or control system
connected to these ports is set for 38400 baud.
See “
” for additional details on connecting the RS-232 port.
USB port details:
The Extron USB driver must be installed before use (see “
”
for
driver installation instructions).
RS-232 Port
The DMP 44 LC has one serial port that can be connected to a host device such as a
computer running the HyperTerminal utility, DSP Configurator, or the DataViewer utility.
The port makes serial control of the DMP possible. Use the protocol information listed
above to make the connection. After the connection is made, see “
”
later in this section for SIS programming details.
