About This Guide
This guide describes installation, operation, control procedures, and reference information
for the FOX T USW 203 Universal Switcher with an integrated fiber optic transmitter. In this
guide, the terms “FOX T USW 203” and “switcher” are used interchangeably to refer to the
FOX T USW 203 switcher with an integrated fiber optic transmitter in singlemode or
multimode.
About the FOX T USW 203
The Extron FOX T USW 203 is a three input universal switcher with a 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 transmitter delivers
pixel-for-pixel transmission of images up to 1920x1200, including HDTV 1080p/60.
The switcher and a compatible FOX Series receiver can be controlled and configured using
Simple Instruction Set (SIS) commands (see Simple Instruction Set Control on page 12) or
the FOX Extenders Control Program (see FOX Extenders Control Program on page 20).
System Compatibility
The FOX T USW 203 operates in either of two modes, selected under RS-232 control, for
compatibility with other, non-HDMI, units:
• Plus — Supports resolutions up to 1920x1200 and 1080p @ 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 @ 60 Hz. 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 203 MM) or singlemode (FOX T USW 203 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 203 Universal Switcher • Introduction
Key Features

Contact closure remote control availability
Alarm notification for fiber link loss — The FOX T USW 203 can be set up to trigger an
external control system for immediate notification when a fiber link has been lost. Requires a
second fiber link.
Multimode and singlemode availability — Available as an 850 nm multimode model for
long-range transmissions up to 2 km (6,560 feet), and a 1310 nm singlemode model for
extreme distances up to 30 km (18.75 miles).
Industry standard LC connectors — Provide reliable physical connectivity and precise
fiber core alignment.

Connecting HDMI Connectors
Use an Extron LockIt Lacing Bracket to secure an HDMI cable to each device as follows:
Figure 4. Installing the LockIt Lacing Bracket to Stacked HDMI Connectors
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
Stacked
to which it is fastened to is very thin and can easily be stripped.
4. If desired, repeat steps 2 and 3 for the opposite mounting screw and bracket.
5. Loosely place the included tie wrap around the HDMI connector and the LockIt lacing
bracket as shown.
6. 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.
Wiring for Fiber Communication
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 transmitter 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.

Wiring for RS-232 Over Fiber and Alarm Communication
CONTACT
The RS-232 Over Fiber port is for transmission of serial signals, such as projector control
signals. The alarm port is an internal relay to connect or disconnect a custom alarm circuit.

Figure 5. Wiring the RS-232 Over Fiber and Alarm Connector
ATTENTION: The length of exposed wires is critical. The ideal length is
3/16 inch (5 mm).
• Longer bare wires can short together.
• Shorter wires are not as secure in the connectors and could be pulled out.
Cross the Tx and Rx lines once between the source and the target.

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
power supply and the unit. The ridges on the side of the cord identify the power cord
negative lead.
• The length of the exposed (stripped) copper wires is important. The ideal length is
3/16 inch (5 mm).
TIP: Do not tin the stripped power supply leads. Tinned wires are not as secure in the
captive screw connectors and could be pulled out.
