command signals to the receiver, for serial control of a projector for example,
connect the host device to the transmitter via the first three leftmost poles
(Tx, Rx, and

) of this 5-pole captive screw connector (see “
“ on page 15 to wire this connector).
NOTES: • If you connect only one fiber optic cable (
configure the receiver for daisy-chaining, you will not receive reports
from the controlled device. To receive responses from the controlled
device, you must install two fiber optic cables and leave the FOXBOX
receiver in normal configuration (Mode DIP switch 1 down on the receiver).
• The FOXBOX can pass RS-232 commands and responses at rates up to
115200 baud.

link 2, connect a locally-constructed or furnished monitoring device to the
transmitter via the two rightmost poles (1 and 2) of this 5-pole captive screw
connector. When the transmitter does not detect a light link on fiber cable
Rx (optional), pin 1 and pin 2 of this port are shorted together (see “

f
Fiber optic connectors and LEDs —
WARNING: These units output continuous invisible light, which may be harmful to
the eyes; use with caution. For additional safety, plug the attached dust
caps into the optical transceivers when the fiber cable is unplugged.
NOTES: • Ensure that you use the proper fiber cable for your transmitter/receiver
pair. Typically, singlemode fiber has a yellow jacket and multimode cable
has an orange or aqua jacket.
• Only one fiber optic cable, transmitter Tx to receiver Rx, is required for
video, audio, and serial command transmission. But, if you connect only
one fiber optic cable, or if your transmitter is configured to daisy-chain
the optical signal, system functionality is reduced. You will not receive
RS-232 reports from the controlled device, and some FOX Extender
Control Program functions and RS-232 commands will not work. To
receive responses from the controlled device and for full functionality, you
need to install both fiber optic cables and leave the FOXBOX receiver in
normal configuration (Mode DIP switch 1 down on the receiver).
ä
Tx (required) — For all one-way video, audio, and serial
communications from the transmitter to the receiver, connect a
fiber optic cable to the Tx LC connector.
Connect the free end of this fiber optic cable to the Rx connector
on the FOXBOX Rx receiver (
on figure 4) or to any other
compatible Extron FOX device.
ã
Rx (optional) — Connect a fiber optic cable for all one-way return
serial communications from the receiver to the transmitter.
Connect the free end of this fiber optic cable to the Tx connector
on a FOXBOX Rx receiver in normal configuration (
figure 4) or to any other compatible Extron FOX device.
Tx Link and Rx Link LEDs — When lit, the link is active (light is
received).
