NConfiguration 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 number 70-335-01(see figure 9), can be used for this connection.

NOTE: This port parallels the rear panel RS-232 Secondary port. If a front panel

configuration connection is made, the rear panel RS-232 Secondary port becomes inactive and the front panel Configuration port is active.

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

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

NOTES: • The Configuration port can operate at 9600, 19200, 38400, or 115200

baud rates. See “Selecting the Baud Rate of the RS-232 Primary

Port” in the “Operation” section to configure all ports under SIS 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.
