SIS™ Control

The GSS 100’s rear panel RS-232 connector (figure 4-1) can be connected to the serial port of a host device, such as a computer or control system. Communications with the GSS are via Extron’s Simple Instruction Set™ (SIS™) or Extron’s Windows- based control program.

	PIN	RS-232	Function
	1	—	None
RS-232	2	TX	Transmit data
	3	RX	Receive data
	4	—	None
	5	Gnd	Ground
	6	—	None
	7	—	None
	8	—	None
	9	—	None

The baud rate for the rear panel RS-232 port can be set to a variety of different rates. The default protocol for the port is as follows:

•	9600 baud	•	no parity
•	8-bit, 1 stop bit	•	no flow control
