About the FOXBOX Tx/Rx HDMI
The FOXBOX HDMI Fiber Optic Extender is an ultra-high performance fiber optic transmitter
and receiver set for long haul transmission of HDCP-compliant HDMI video, audio, and
RS-232 control signals over fiber optic cabling. The transmitter and receiver can extend
HDMI signals up to 30 km (18 miles).
NOTE: For HDCP compliance:
• A FOXBOX HDMI or PowerCage FOX HDMI transmitter must be paired with
a FOXBOX HDMI or PowerCage FOX HDMI receiver.
• You must connect both fiber optic cables between the transmitter and
receiver.
• A signal cannot be daisy-chained and retain HDCP compliance.
• The bidirectional Consumer Electronics Control (CEC) is not supported.
Transmitter
The FOXBOX Tx HDMI transmitter accepts HDMI video or DVI-D video (with an applicable
adapter), at resolutions up to 1920 x 1200 at 60 Hz. The video input can also include
embedded audio. The transmitter also loops the HDMI input through for a local monitor.
The transmitter can also accept an analog audio input on 3.5 mm mini jack. A front panel
DIP switch selects either the embedded audio or the separate analog audio for the unit to
transmit to the receiver.
The transmitter accepts a one-way (transmitter-to-receiver) RS-232 serial communication
(for applications such as projector control) serial signal input. The transmitter can receive an
optional return (receiver-to-transmitter) stream of serial RS-232 communications, such as
projector responses.
The transmitter converts the HDMI video, the selected audio, and the RS-232 serial
communication into a proprietary data stream and outputs it as an optical signal on a single
LC connector to a compatible fiber optic receiver. It also can receive a proprietary optical
signal from the receiver consisting of the RS-232 return from a controlled device.
Receiver
The FOXBOX Rx HDMI receiver accepts a proprietary optical signal on a single LC connector
from a compatible fiber optic transmitter or daisy-chained receiver.
The receiver outputs a single link of HDMI video, digital audio (embedded in the HDMI
output), analog audio, and RS-232 serial commands.
If the receiver is appropriately configured and has a second fiber optic cable installed, it also
can either:
• Receive an RS-232 return from a controlled device and send it to the transmitter via a
proprietary optical signal.
• Output a daisy-chained signal to another receiver.
If either RS-232 return or daisy-chained communications are implemented, the receiver
outputs a proprietary signal on the second fiber optic cable carrying the signal.
For video resolutions up to 1600 x 1200, 1080p, or 1920 x 1200, the video output of the
receiver is a perfect, pixel-for-pixel recreation of the video signal input to the transmitter.
With the appropriate adapter, the single link of HDMI video output by FOXBOX Rx HDMI can
be converted to DVI-D video.
The receiver has built-in alternating pixels, color bars, and grayscale test patterns to assist in
setting up the display equipment.
