a
Configuration port — This 2.5 mm mini stereo jack serves the same communications
function as the rear panel RS-232/RS-422 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 (see figure 28), can be used for this connection.

NOTES:
• This port is independent of the rear panel RS-232/RS-422 port and is not
affected by changes to the protocol of the rear panel port. The protocol of this
front panel port can be changed, under SIS command control only. See the
Command and Response table for IP SIS commands, on page XX, to configure
all ports under SIS control.
• A front panel Configuration port connection and a rear panel RS-232/RS-422
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
• 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.
