CAUTION!
The transmitter unit contains a laser-emitting diode located in the optical connector.
This device emits invisible infrared electromagnetic radiation that can be harmful to
human eyes. The radiation from this optical connector, if viewed closely without any
protection, may cause instantaneous damage to the retina of the eye. Direct viewing
of this LED should be avoided at all times.

INSTALLATION INSTRUCTIONS
Installation Procedure
The VERSITRON VersiVision FVTM4B2x and FVRM4B2x video transmission systems
series are preset for immediate use. There are indicator LEDs on the units for monitoring the
real-time status of video, data and power. The following instructions describe the typical
installation procedure and the function of the LED indicators located on each unit.
1. Connect the video source (camera) to the video input BNC connector on the transmitter
unit (FVTM4B2x) using coaxial cable.
2. Connect the video output BNC connector on the receiver unit (FVRM4B2x) to the video
monitor using coaxial cable.
3. Connect the fiber optic cable between the transmitter and receiver units.
4. Apply the power supply to both the transmitter and receiver units.
5. When the power is applied, the orange POWER LED will light, indicating the presence
of operating power. The blue VIDEO LED and the blue DATA LED will give an
indication as stated on the following pages.
6. The system should now be operational.

Indicator LEDs
The stand-alone units have integral LEDs that are used to monitor the state of the unit. There
are four video LEDs, one power LED and one data LED on each unit. The indicator LEDs
function as follows:
TRANSMITTER and RECEIVER:
Power: ON: (Orange) Indicates that correct power has been applied
Transmitter:
Video: OFF: Indicates no video detected on input BNC connector
(No Video present on input BNC)
ON: (Blue) Indicates video detected on input BNC connector
(Video present on input BNC)
Data: OFF: Indicates no data detected on the transmit data cable
Blinking: (Blue) Indicates data transmitted at the rate of the operation data.
*Front Panel of FVTM4B2x (Transmitter)
Receiver:
Video: OFF: Indicates no video present on output BNC connector
(No Video present on output BNC)
ON: (Blue) Indicates video detected on output BNC connector
(Video present on input BNC)
Data: OFF: Indicates no data detected on the receive data cable
Blinking: (Blue) Indicates data received at the rate of the operation data.

TROUBLESHOOTING
Optical Fiber
The VERSITRON VersiVision FVTM4B2x and FVRM4B2x video transmission systems
series is available for most applications using singlemode optical fibers. Please be certain
that the correct size and type of the fiber is being used for the particular transmitter/receiver
combination.
Also be certain that the attenuation and bandwidth of the fiber optic cable being used is
within the range of the system’s loss budget specifications.
General
Any dirt or dust may easily pollute or block the fiber from accepting or radiating light.
Therefore, please try to keep the optical connector clear and always use the dust caps
whenever the connector is exposed to air. It is suggested that the tip of the optical connecter
should be carefully cleaned with a lint-free cloth moistened with alcohol from time to time.
The status of any of the VIDEO LED should provide the first clue as to the origin of any
operational failure. If the VIDEO LED on the receiver unit is off, it usually means that the
fiber is broken or has too much attenuation.
Please also make sure that the transmitter and the receiver are not used in opposite positions.
If the system is still not working after examining the above possibilities, please contact our
Customer Service Department for further assistance
Data Link
Even when installed exactly as directed, it is possible that the data/audio function may fail to
operate properly. If this problem occurs, first please check the data cable, and then check
whether the data cable connector is firmly inserted into the RJ-45 port.
If the system is still not working after examining the above possibilities, please contact our
Customer Service Department for further assistance
