NOTE:	The stereo jack Configuration port (item o) protocol can be changed
	under SIS command control only (see the Set serial port parameters
	SIS Command, in the “Programming Guide” section to configure all ports
	under SIS control).

This port is RS-232 only, with its default protocols as follows:

•9600 baud

•1 stop bit

• no parity • 8 data bits

•no flow control

NOTE: The maximum distances from the matrix switcher to the controlling device

can vary up to 200 feet (61 m). Factors such as cable gauge, baud rates,

environment, and output levels (from the switcher and the controlling

device) all affect transmission distance. Distances of about 50 feet (15 m)

are typically not a problem. In some cases the matrix switcher may be capable of serial communications via RS-232 up to 250 feet (76 m) away.
