Confi guration 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 than the rear port 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
(fi gure 2-8), can be used for this connection.

This port parallels the rear panel RS-232 Secondary port. If a front panel
confi guration connection is made, the rear panel RS-232 Secondary port becomes
inactive and the front panel Confi guration port is active..
This port is RS-232 only, with its default protocols as follows:
• 9600 baud
• no parity
• 8 data bits
• 1 stop bit
• no fl ow control
N
The
Confi guration port can operate at 9600, 19200, 38400, or 115200 baud
rates. See
Command/Response table for IP SIS commands
, in chapter 4,
SIS Programming and Control
, to confi gure all ports under SIS control.
N
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.
