Confi guration port — This 2.5 mm mini stereo jack (fi gure 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 (fi gure 2-15) can be used for this connection.

N The 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.
N This 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 fl ow control
