AC power connector — Plug a standard IEC power cord into this connector to connect the scaler to a 100 to 240 VAC, 50 Hz or 60 Hz power source. The front panel LCD display and input selection LEDs will light during power-up.

Video input 1: Composite video — Connect a composite video signal to this female BNC connector.

Video input 2: S-video — Connect an S-video signal to this 4-pin mini-DIN female connector.

RGB 15-pin HD video output — Connect an RGB video display.

Remote (RS-232/contact closure) 9-pin port — This connector provides for two-wayRS-232 communication and contact closure control. See chapter 3, “Serial Communication”, for information on how to use the 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	–	No connection
2	Tx	Transmit data	5		1
3	Rx	Receive data
4	Input #1	Contact closure
5	Gnd	Signal ground		9	6
6	Input #2	Contact closure
7	–	No connection	DB9 Pin Locations
				Female
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 the 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.
