About the FOX II DP Transmitter and Receiver
The FOX II DP Transmitter and Receiver are an ultra-high performance fiber optic Extender
set for long haul transmission of HDCP-compliant DisplayPort video, audio, and RS-232
and IR control signals over fiber optic cabling. The transmitter and receiver can extend
DisplayPort signals up to 30 km (18 miles).
Transmitter
The FOX II T DP transmitter accepts DisplayPort video, at a resolution of up to 2560x1600
and a data rate of up to 10.8 Gbps (2.7 Gbps per lane). The video input can also include
embedded audio. The transmitter also loops the DisplayPort input through for a local
monitor.
The transmitter can also accept an analog audio input on either a 3.5 mm mini jack or a
5-pole captive screw connector. The transmitter automatically detects whether embedded
audio is present on the DisplayPort input and if none, selects the analog audio for the unit to
embed in the digital video stream and transmit to the receiver. An RS-232 Simple Instruction
Set (SIS) command selects either audio.
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 DisplayPort 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 and an
audio return channel.
The transmitter has a built-in color bars test pattern to assist in setting up the display
equipment.
Receiver
The FOX II R DP receiver accepts a proprietary optical signal on a single LC connector from
a compatible fiber optic transmitter.
The receiver outputs DisplayPort video, digital audio (embedded in the DisplayPort output),
analog audio, and RS-232 serial and IR commands.
If the receiver is appropriately configured and has a second fiber optic cable installed, it also
can receive an RS-232 return from a controlled device and send it to the transmitter via a
proprietary optical signal.
If RS-232 return is implemented, the receiver outputs a proprietary signal on the second
fiber optic cable carrying the RS-232 signal.
For video resolutions up to 2560x1600, the video output of the receiver is a perfect,
pixel-for-pixel recreation of the video signal input to the transmitter.
Both Units
The transmitter and receiver have many controls, including audio adjustments, that are
available under RS-232 SIS control. Both units have video, audio, fiber light status, and
lost-light alarm indicators.
