CAUTION: Installation and service must be performed by authorized personnel only.
These instructions provide a quick setup guide for the Extron
® FOX Tx/Rx AV. They are for
use by experienced installers.
The FOX Tx AV and FOX Rx AV are a high performance, low resolution video, audio, and
data (RS-232) transmitter (Tx) and receiver (Rx) pair. Both the transmitter and receiver are
available in single mode (SM) and multi-mode (MM) models. The SM models transmit signals up to 30 km (18 miles) over
fiber optic cable, at rates up to 2 Gbps.
WARNING: The FOX Tx/Rx AV outputs continuous invisible light (Class 1 rated), which may be harmful and dangerous
to the eyes; use with caution.
Do not look into the rear panel fiber optic cable connectors or into the fiber optic cables themselves.
NOTES: The transmitter and receiver must be compatible. Both must be MM or both must be SM. It is not possible to mix
types.
Plug the attached dust caps into the optical transceivers when the fiber optic cable is unplugged.
To install, cable, and power on the transmitter/receiver pair:
Step 1
Turn off all equipment or disconnect it from power sources. Mount the transmitter and receiver as required.
Step 2
Connect a low resolution video source to the transmitter using the input BNC connections for composite or component
sources. S-video can be connected using either the BNC connectors or the 4-pin mini DIN. (See the figure below).

Step 3
Connect balanced or unbalanced, stereo or mono audio input to the transmitter using the 5-pole, 3.5 mm captive screw
connector (see the figure below).

Step 4
If required, connect an alarm system to the 2-pole captive screw connector (marked Alarm) on the transmitter.
Step 5
To configure the transmitter and receiver using RS-232 commands, connect a control device to the three
right poles ( , Tx, and Rx), labeled RS-232 Remote, on the RS-232 captive screw connector of the transmitter
(see the figure at right). Alternatively, the host device can be connected through the front panel Config
port or the corresponding ports on the receiver (see step 13). These ports may also be used to configure the
system with the FOX Extender Windows
®
Control Program.

Step 7
Connect the 12 VDC power supply to the 2-pole captive screw connector on the transmitter. Do not switch on the power
supply.
Step 8
Connect the receiver to a low resolution video display using either the output BNC connectors (component, S-video, or
composite) or the 4-pin mini DIN (S-video only), as shown in the figure below.

Step 9
Connect the audio output from the receiver to a sound system, using the 5 pole, 3.5 mm captive screw connector.
Step 10
If required, connect an alarm system to the 2-pole captive screw connector (marked Alarm) on the receiver.
Step 11
Connect the fiber optic cable(s) from the transmitter to the back of the receiver (see the figure below). Fiber optic link 1
connects the Tx port of the transmitter to the Rx port of the receiver and is essential for transmission of video, audio, and
control signals from the transmitter to the receiver. Fiber optic link 2 connects the Rx port of the transmitter to the Tx
port of the receiver. Although it is optional, two-way communication from the Tx port of the receiver is required to fully
configure the system using RS-232 commands or FOX Extender Windows Control Program.

Link 2 may be connected to another receiver in a daisy chain. In that case, there is no return link to the transmitter.
Step 12
Connect an RS-232 control device to the 5-pole captive screw connector or the front panel Config port of the receiver. These
ports are an alternative to the transmitter ports (see steps 5 and 6).
NOTE: If the RS-232 control device is connected to the receiver, fiber optic link 2 is required to configure the transmitter.
Step 13
Connect the 12 VDC power supply to the 2-pole captive screw connector of the receiver.
Step 14
Power up all devices and configure the system using the Simple Instruction Set (SIS™) commands or FOX Extender Windows
Control Program. Consult the user guide (available online at www.extron.com) for more information about SIS commands
and the Control Program.
