Serial Ports

The DXP switcher can support either RS-232 or RS-422 serial communication protocol, and can operate at 9600, 19200, 38400, or 115200 baud rates. See “Selecting the RS-232/RS-422 Protocol and Baud Rate (Rear Panel)” on page 44 to configure this port from the front panel.

The DXP has two connectors that can be used for serial control. Both ports enable use of SIS commands and the control software. The default protocol for these ports is:

9600 baud, 8 data bits, 1 stop bit, no parity, and no flow control.

Rear Panel RS-232/RS-422 Port: The rear panel 9-pin D female connector labeled Remote RS232/RS422 can be connected to the RS-232 or RS-422 serial port of a host device such as a computer running the Extron DataViewer or the HyperTerminal utility, an RS-232 capable PDA, or a control system.

For the pin assignments for this port, see “Remote RS232/RS422 port (rear panel)” on page 11.

Front Panel RS-232 Port: The front panel TRS connector labeled Config can be connected to a host device for RS-232 control only.

The optional 2.5 mm cable (Extron part number 70-335-01) can be used to connect the DXP to the host. For connection information for this cable, see RS-232 Config port (front panel)” on page 11.
