I	Configuration port — This 2.5 mm mini stereo jack serves the same serial
	communications function as the rear panel Remote port, but it is easier to
	access after the matrix switcher has been installed and cabled. The optional
	9-pin D to 2.5 mm mini jack TRS RS-232 cable, part #70-335-01(figure 2-9), can
	be used for this connection.

NThis port is independent of the rear panel Remote port and is not affected by changes to the rear panel port’s protocol. This front panel port’s protocol can be changed, under SIS command control only. See the Command/Response table for IP SIS commands, in chapter 4, “Programmer’s Guide”, to configure all ports under SIS control.

NA front panel Configuration port connection and a rear panel Remote port connection can both be active at the same time.

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

•	9600 baud	•	no parity	• 8 data bits
•	1 stop bit	•	no flow control

NThe 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.
