Conﬁguration 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 (ﬁgure 2-12), can be used for this connection.

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.
