LRemote (RS-232/contact closure) port — This 9-pin connector provides for two- way RS-232 communication. See the “SIS Communication and Control” chapter 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	Ground	Signal ground
6	Input 3	Contact closure
7	Input 4	Contact closure
8	-	No connection
9	-	Reserved

Figure 7. RS-232 Pin-out

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).

NOTE: If contact closure is not in use, pins 1, 4, 6, and 7 should have no

connection.
