K	Remote (RS-232/contact closure) 9-pin port — This connector
	provides for two-way RS-232 communication. See chapter 3,
	“Serial Communication”, for information on how to install and
	use the control software and SIS commands.

RS-232

51

96

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	–	Reserved

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

To select a different input number using a contact closure device, short the pin for the desired input number to logic ground (pin 5).
