INTRODUCTION
The XTENDEX®SD/HD/3G-SDI Extender via Fiber Optic Cable locates up to two displays from a SD/HD/3G-SDI video source
up to 12.4 miles (20 kilometers) away using a single singlemode LC fiber optic strand and 1,640 feet (500 meters) using
multimode fiber optic cable (OM2 and above). Each extender consists of a transmitter that connects to a SD/HD/3G-SDI video
source and a local loop out, and a receiver that connects to up to two SD/HD/3G-SDI displays.
Features:
Signal transmission via one singlemode or multimode LC fiber optic cable.
oUsing singlemode 9-micron cable, extend to 12.4 miles (20 kilometers).
oUsing multimode 50-micron cable, extend to 1,640 feet (500 meters).
Supports HDTV resolutions to 1080p @60Hz.
Simultaneously transmits to two SD/HD/3G-SDI displays at the receiver.
Supports a local display via loop out SDI connector.
Supports unidirectional RS485 from the receiver to the transmitter.
Plug-and-play functionality –no software needed.
Low RFI/EMI for sensitive applications.
Cables can be installed in conduit prior to extender installation.
Integrated mounting brackets for easy surface/wall mounting.
Available power options: 5VDC or 12VDC

ST-1FO3GSDI-12VLC power jack will be labeled "DC 12V" instead.
10 GND Symbol Ground Screw For connecting earth ground wire
11 FIBER Green LED Status LED to indicate an SDI video signal from the Local Unit
12SDI OUT BNC Female For connecting BNC cable from SDI display device

LED Behavior
Local PWR - Illuminates when the Local Unit has power ON.
Remote PWR - Illuminates when the Remote Unit has power ON.
Local and Remote FIBER - If there is no source connected to "SDI IN", but there is a fiber between the Local and Remote Unit,
the "FIBER" LED on the Local will illuminate, and the "FIBER" LED on the Remote will not.
If a source is connected to "SDI IN", the "PWR", "FIBER" and "SDI" LEDs on the Local and Remote
Unit will illuminate.
Local and Remote DATA - When an active RS485 signal is present, this LED will blink.

PREPARATION FOR INSTALLATION
Locations should be chosen for the monitor that also has space to connect the Remote unit within the distance provided by
the cables.
All cables should be installed in such a way that they do not cause stress on their connections to the equipment. Extended
lengths of cable hanging from a connection may interfere with the quality of that connection. Secure cables as needed to
minimize this.
The RG6 cables must be routed such that the cables are away from any sources of magnetic fields or electrical interference
that might reduce the quality of the video signal (i.e. AC motors, welding equipment, etc.).
Properly shut down and disconnect the power from the video source and monitor(s) to be separated. If other equipment is
involved whose connections are being interrupted, be sure to refer to the instruction manuals for that equipment for proper
disconnection and reconnection procedures before proceeding.

CONNECTIONS
1. Connect camera or other output device to "SDI IN" BNC connector on the Local Unit.
2. If the output device has RS485 control connections, connect the "-" wire to terminal "2" and the "+" wire to terminal
"1" of the Local Unit.
3. Optionally connect an SDI display to the "SDI LOOP" BNC connector on the Local Unit.
4. Connect type LC simplex fiber optic cable between the Local Unit and Remote Unit.
5. Power ON the Output device and SDI display (if installed).
6. Connect a DC adapter to the Local Unit and power the Local Unit ON.

Problem Solution
Local Unit
Power LED not working Check power connections thoroughly.
No Video Signal Check the SDI LED on the Remote Unit.
If LED illuminates, it means there is a video signal on this channel. Check
the connections of the video display equipment.
If LED is dark, it means there is no video signal to the Remote Unit.
Check if the SDI LED on the Local Unit is illuminated or not. Cycle power
on the Remote and Local Units to sync the signals up.
Display has "snow" interference This is normally caused by attenuation of the fiber cable or a long cable
between the video source and the Local Unit. Always use the highest quality
cables available.
1. Make sure the fiber cable does not have any bends in it that exceed the
cables specification
2. Check the cleanliness of the fiber port and fiber cable ends. Clean using
cotton swab and alcohol.
3. Use 75 ohm impedance RG6 cables between the displays and the
Local/Remote units and to the video source. Be sure to route away from
other sources of electromagnetic interference.
