The FOX3T101 transmitter accepts HDMI video, at a resolution of up to 4K
(4096x2160@60Hz). The video input can also include embedded audio. The transmitter
also loops the HDMI input through for a local monitor.
The transmitter converts the HDMI video into a proprietary data stream and outputs it as
optical signals via fiber optic small form factor pluggable (SFP) modules on an LC connector
to a compatible Extron FOX3 fiber optic receiver. The transmitter has a built-in color bars
test pattern to assist in setting up the display equipment.
Receiver
The FOX3R101 receiver accepts an optical signal on one LC connector from a compatible
fiber optic FOX3 transmitter. The receiver is compatible with all Extron FOX3 transmitters.
The receiver outputs HDMI video and digital audio (embedded in the HDMI output). The
video output of the receiver is a lossless HDMI image up to 4K (4096x2160 @ 60 Hz),
including 1080p @ 60 Hz with Deep Color.
Both Units
The transmitter and receiver can be configured and controlled via the front panel USB port
using Simple Instruction Set (SIS) control and Product Configuration Software (PCS). Both
units have video, fiber light status, and lost-light alarm indicators.

Connector and Cable Details
HDMI Connectors
HDMI signals run at a very high frequency and are especially prone to errors caused by bad
video connections, too many adapters, or excessive cable length. To avoid the loss of an
image or jitter, follow these guidelines:
• Limit or avoid the use of adapters.
• Use only cables specifically intended for HDMI or DVI signals.
To securely fasten an HDMI cable to a device:
1. Plug the HDMI cable into the panel connection (see figure5, 1).

Figure 5. Installing the LockIt Lacing Bracket
2. Loosen the HDMI connection mounting screw from the panel enough to allow the
LockIt lacing bracket to be placed over it (2). 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 (3).
ATTENTION:
• Do not overtighten the HDMI connector mounting screw. The shield to which it
fastens is very thin and can easily be stripped.
• Ne serrez pas trop la vis de montage du connecteur HDMI. Le blindage auquel
elle est attachée est très fin et peut facilement être dénudé.
4. Loosely place the included tie wrap around the HDMI connector and the LockIt lacing
bracket (4).
5. While holding the connector securely against the lacing bracket, use pliers or similar
tools to tighten the tie wrap, then remove any excess length (5).

FOX3 T 101 Transmitter and FOX3 R 101 Receiver • Installation and Operation 11
HDCP
Input
The HDMI input negotiates and authenticates HDCP with the source device if the source
requires HDCP encryption. The authentication process is repeated whenever the stored
EDID is changed or updated, which is indicated by pulling HPD low.
HDCP support can be disabled for the input using SIS commands (see HDCP authorized
device on page18) or PCS (see the FOX3T101 and FOX3R101 Help File).
Outputs
The output is pre-authenticated and encrypted, in accordance with the configured HDCP
output mode using PCS (see the FOX3T101 and FOX3R101 Help File).
If an output requires encryption, but the connected sink device cannot be authenticated,
that output displays a green screen.
HDCP output modes
• Follow Input (default) — Output authentication and encryption follows input status.
Authentication times out after ~10 seconds.
• Always Encrypt Output — The output is always authenticated and encrypted.
Authentication times out after ~10 seconds.
• Follow Input (with continuous trials) — Output authentication and encryption follows
input status with no authentication timeout.
• Always Encrypt Output (with continuous trials) — The output is always
authenticated and encrypted with no authentication timeout.
• Disable Authentication — The output is never authenticated or encrypted. When an
HDCP encrypted input signal is detected, the display always shows a green screen.
