About This Guide
This guide describes installation, operation, and control procedures, and reference
information for the FOX T USW 103 Universal Switcher with an integrated fiber optic
transmitter. In this guide, the terms “FOX T USW 103” and “switcher” are used
interchangeably to refer to the FOX T USW 103 Universal Switcher with an integrated fiber
optic transmitter in singlemode or multimode.
About the FOX T USW 103
The Extron FOX T USW 103 is a three input universal switcher with an integrated fiber optic
transmitter that provides long haul transmission of HDCP-compliant HDMI, RGBHV, or HD
component video; stereo audio; and RS-232 signals over fiber optic cabling. The switcher
delivers pixel-for-pixel transmission of images up to 1920x1200, including HDTV 1080p/60.
To configure and control the FOX T USW 103, connect a host device, such as a computer,
and enter Simple Instruction Set (SIS) commands (see Simple Instruction Set Control
on page 12) or use the FOX Extenders Control Program (see FOX Extenders Control
Program on page 20).
System Compatibility
The FOX T USW 103 operates in either of two modes, selected under RS-232 control, for
compatibility with other, non-HDMI, units:
• Plus — Supports resolutions up to 1920x1200 @ 60Hz. The fiber optic output of the
switcher can be received only by one of six receivers: a FOXBOX HDMI Rx,
FOXBOX DVI Plus Rx, PowerCage HDMI Rx, PowerCage FOX DVI Plus Rx,
FOXBOX SR HDMI, and PowerCage FOX SR HDMI.
• Non-Plus — Supports resolutions up to 1600x1200 and 1080p @ 60 Hz (including
HDTV 1080p/60 Hz), is HDCP compliant, and does not contain embedded audio
(analog audio is still supported). The fiber optic output of the transmitter can be received
by any FOXBOX, PowerCage FOX, and FOX 500 VGA and DVI unit, including the Plus
and non-Plus units.
Cable Transmission Modes
The transmitter is further categorized by the type of fiber optic cable, multimode
(FOX T USW 103 MM) or singlemode (FOX T USW 103 SM), which define the effective
range of transmission:
• Multimode — Long distance, up to 2 km (6,560 feet) (depending on the fiber cable)
• Singlemode — Very long distance, up to 30 km (18.75 miles)
1FOX T USW 103 Universal Switcher • Introduction
Key Features

All digital technology — Delivers pixel-for-pixel transmission of video signals to ensure
optimal image quality at resolutions up to 1920x1200, including HDTV 1080p/60.
Digital conversion of analog video and audio input signals — Digitizes analog signals,
ensuring that a reliable, high quality digital video signal is sent to the output destination.
Auto-input switching — Automatically switches to the highest or lowest priority input with
an active video signal for simplified operation.
HDCP-compliance
Key Minder — Authenticates and maintains continuous HDCP encryption between input
and output devices to ensure quick and reliable switching in professional AV environments,
while enabling simultaneous distribution of a single source signal to one or more displays.

Fiber Optic Connector
Fiber optic connector — For one-way video, audio, and serial communication from
d
the FOX T USW 103 to a receiver, connect a fiber optic cable between the Tx port on
the FOX T USW 103 and the Rx port on a receiver.
To return serial data from a receiver to the FOX T USW 103 or for HDCP-compliance,
connect a fiber optic cable between the Rx port on the FOX T USW 103 and the Tx port
on the receiver (see Wiring for Fiber Communication on page 7).
NOTES:
• Ensure the proper fiber optic cable is used. Typically, singlemode fiber optic
cable has a yellow jacket and multimode fiber optic cable has an orange or aqua
jacket.
• Only one fiber optic cable, transmitter-Tx-to-receiver-Rx, is required for video,
audio, serial command transmission, but the HDMI signal output on the receiver
will not be HDCP-compliant and the FOX T USW 103 will not receive RS-232
reports from the controlled device.

(for serial control of a projector, for example), connect a host device to
the switcher via the leftmost poles (Tx, Rx, and G) of this 5-pole captive
screw connector (see Wiring for RS-232 Over Fiber and Alarm
Communication on page 8 for wiring configurations).
Alarm port — For remote monitoring of the status of fiber optic link 2,
connect a custom or furnished monitoring device to the switcher via the
rightmost poles (1 and 2) of this 5-pole captive screw connector (see
Wiring for RS-232 Over Fiber and Alarm Communication on page 8).
NOTE: Pins 1 and 2 short within the switcher when link 2 does not detect any
connection.

Use an Extron LockIt Lacing Bracket to secure an HDMI cable to each device as follows:
3

1
Figure 4. Installing the LockIt Lacing Bracket
1. Plug the HDMI cable into the panel connector.
2. Loosen the HDMI connection mounting screw from the panel enough to allow the
LockIt lacing bracket to be placed over it. The screw does not have to be removed.
3. Place the LockIt lacing bracket on the screw and against the HDMI connector, then
tighten the screw to secure the bracket.
ATTENTION: Do not overtighten the HDMI connector mounting screw. The shield
to which it is fastened to is very thin and can easily be stripped.
4. Loosely place the included tie wrap around the HDMI connector and the LockIt lacing
bracket as shown.
5. While holding the connector securely against the lacing bracket, use pliers or a similar
tool to tighten the tie wrap, then remove any excess length.

WARNING: Risk of serious physical injury. This device outputs
continuous invisible light, which may be harmful to the eyes; use with
caution.
• Do not look into the rear panel fiber optic cable connectors or into
the fiber optic cables themselves.
• Plug the attached dust caps into the optical transceivers when the
fiber cable is unplugged.
NOTES:
• Ensure the proper fiber optic cable is used for the
FOX T USW 103 and receiver. Typically, singlemode fiber optic
cable has a yellow jacket and multimode fiber optic cable has an
orange or aqua jacket.
• Only one fiber optic cable, transmitter-Tx-to-reciever-Rx, is
required for video, audio, and serial command transmission.
However, for only one fiber optic cable:
• The HDMI signal output by the receiver is not HDCP compliant.
• RS-232 reports from a controlled device are not available.
• To receive responses from the controlled device and for
HDCP-compliance, install both fiber optic cables.

• Longer bare wires can short together.
• Shorter wires are not as secure in the connectors and could be pulled out.

Alarm Device
For RS-232 over fiber connection, cross the Tx and Rx lines once between the source and
the target.
The alarm pins do not produce any discrete on or off or voltage signals.
NOTES:
• The alarm port does not produce any discrete on or off voltage signals.
• If power is lost or if link 2 optical light is disconnected, lost, or broken, alarm pins 1

Ridges
SECTION A–A
ATTENTION:
• This product is intended to be supplied by a Listed Power Unit marked “Class 2”
or “LPS,” rated 12 VDC, 1.0 A minimum. Always use a power supply supplied by
or specified by Extron. Use of an unauthorized power supply voids all regulatory
compliance certification and may cause damage to the supply and the end product.
• Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling
spaces or in wall cavities. The installation must always be in accordance with the
applicable provisions of National Electrical Code ANSI/NFPA 70, article 75 and
the Canadian Electrical Code part 1, section 16. The power supply shall not be
permanently fixed to a building structure or similar structure.
• Power supply voltage polarity is critical. Incorrect voltage polarity can damage the
