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.
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).
