Front Panel Configuration Port

m Configuration port — This 2.5 mm mini stereo jack (figure 2-14) serves the same serial communications function as the rear panel Remote port, but it may easier to access. The optional 9-pin D to 2.5 mm stereo mini TRS RS-232 cable, part #70-335-01(figure 2-15) can be used for this connection.

NThe maximum distances from the matrix switcher to the controlling device can vary up to 200' (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' (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' (76 m) away.

NThis port is completely separate from 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.

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

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