RGB or HD component (R-Y, Y, B-Y) 15-pin HD video output — Connect an RGB video display or HD component video display to this connector.

Remote (RS-232/contact closure) 9-pin port — This connector provides for two-wayRS-232 communication and contact closure control. See chapter three, “Serial Communication”, for information on how to install and use the control software and SIS commands.

The default protocol is 9600 baud, 1 stop bit, no parity, and no flow control.

The rear panel RS-232 9-pin D female connector has the following pin assignments:

Pin	RS-232 function	Description
1	Input #1	Contact closure
2	Tx	Transmit data
3	Rx	Receive data
4	Input #2	Contact closure
5	Gnd	Signal ground
6	Input #3	Contact closure
7	Input #4	Contact closure
8	–	No connection
9	Hardwired IR	IR input

The Remote connector also provides a way to select an input using a remote contact closure device. Contact closure control uses pins on the Remote connector that are not used by the RS-232 interface (see preceding table).

To select a different input number using a contact closure device, momentarily short the pin for the desired input number to logic ground (pin 5). To force one of the inputs to be always selected, leave the short to logic ground in place. The short overrides front panel input selections.
