o 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: • You can connect the transmitter to one or more receivers in one of three
ways:
• One way (transmitter-Tx-to-receiver-Rx) only — Connect fiber
cable
15a
(from transmitter connector
ä
) only.
• Two way (transmitter to receiver and return) — Connect fiber
cable
15a
(from transmitter connector
ä
) and fiber cable
15b
back to the
transmitter (connector
è
). See figure 5.
• One way (transmitter to receiver) with daisy
chain (receiver to receiver) — Connect fiber
cable
15a
from a fiber optic source and cable
15b
to
the next receiver in the daisy chain. See figure 6.
Set each receiver in the daisy chain to daisy
chain mode (Mode DIP switch 1 up.)
Up to 10 properly-configured receivers can
be connected in a daisy chain to a single
transmitter.
• See the transmitter fiber connector NOTES on
page 9, which also apply to these connectors.

Rx (required) — For all one-way video, audio, and serial communications from the
transmitter to the receiver, connect a fiber optic cable to the Rx LC connector.
Connect the free end of this fiber optic cable to the Tx connector on the FOXBOX Tx
transmitter (item
f
on page 9) or to any other compatible Extron FOXBOX device.
15b
Tx (optional) — Connect a fiber optic cable to the Tx LC connector for either of
the following functions:
Normal configuration — For all one-way return serial communications from the
receiver to the Rx connector on the transmitter. See figure 5.
Daisy chain configuration — For daisy-chained video, audio, and serial
communications to the Rx connector on another receiver. See figure 6.
NOTE: The Tx connector emits light in either case and the Rx port receives light.
Connect the free end of this fiber optic cable to either:
• The Rx connector on the FOXBOX Tx transmitter (item
f
on page 9) or to any
other compatible Extron FOX device
• The Rx connector on another receiver in the daisy chain
Tx Link and Rx Link LEDs — When lit, the link is active (light is received).
