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 RS232 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 “Software Control.”

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 RS-232 Port” for additional details on connecting the RS232 port.

USB port details:

The Extron USB driver must be installed before use (see “Install the USB Driver” 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 “Using the Command/ Response Tables” later in this section for SIS programming details.
