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 42 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 10.
• 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 10.
