RS-232 Ports

Both the FOX Tx AV and FOX Rx AV have a front panel TRS port and a rear panel captive

screw port, which can provide SIS commands to conﬁgure the transmitter/receiver settings

when connected to a control device.

SIS commands for the FOX Tx/Rx AV start on page 13.

NOTE: The two comm ports work in parallel. However, depending on the computer or

the communication settings, connecting to both comm ports at once may result

in one or both ports not working. Extron recommends that only one comm port

(front or back) is used at a time.

The protocol for both ports is 9600 baud, no parity, 8 data bits, 1 stop bit, and no ﬂow

control.

NOTE: Both RS-232 Remote and RS-232 Over Fiber signals require ﬁber optic link 1 and

link 2 for full functionality (see page 12).

The front panel Conﬁg port uses a 2.5 mm mini jack connector. Extron recommends the

9-pin D Female to 2.5 mm TRS Conﬁguration Cable (part number 70-335-01)
