PowerCage FOX SR HDMI Scaling Receiver • Installation and Operation 6
Ä
Rx — 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 a
PowerCage FOX or FOXBOX transmitter or to any other compatible Extron fiber
optic device.
Å
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 a compatible transmitter ( see figure
3 on page 5).
Daisy chain configuration — For daisy-chained video, audio, and serial
communications to the Rx connector on another receiver ( see figure
4 on page 5).
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 of the following:
• The Rx connector on a compatible transmitter 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).

amplifier or powered speakers to this 5-pole, 3.5 mm captive screw
connector to output the transmitted, unamplified, line level audio (see “

command signals to a slave device, for serial control of a projector for
example, connect the slave device to the receiver via the first three leftmost
poles (Tx, Rx, and _) of this 5-pole captive screw connector ( see “

connectors “ on page 9 to wire this connector).
NOTES: • If you connect only one fiber optic cable (see item Ä , above), or you
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 link 2 enabled
(via an
SIS command [see page 18] or using the Signal Processing
Product Control Program [see page 24]).
• The PowerCage FOX can pass RS-232 commands and responses at rates
up to 115200 baud.

receiver via the two rightmost poles (1 and 2) of this 5-pole captive screw
connector. When the receiver does not detect a light link on fiber cable Rx,
pin 1 and pin 2 of this port are shorted together (see “
Alarm outputs connection “ on
page 9 to wire this connector).
