GENERAL INFORMATION

Introduction:

The VERSITRON VersiVision FVTM880x and FVRM880x Series video and data transmitter and receiver support simultaneous transmission of 8-channels of 8-bit digitally encoded video and return data over one multi-mode or single-mode optical fiber. The units are universally compatible with major camera systems and support the RS-485 data protocol. Plug and Play design ensures ease of installation and electronic and optical adjustments are never required.

OPTICAL POWER BUDGET

Optical transmission distance is limited to optical loss of the fiber and any additional loss caused by connectors, splices, and patch panels.

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 FVTM880x and FVRM880x 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 (FVTM880x) using coaxial cable.
2. Connect the video output BNC connector on the receiver unit (FVRM880x) 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 yellow POWER LED will light, indicating the presence of operating power. The blue VIDEO LEDs and the blue DATA LEDs will give an indication as stated on the following pages.
6. The system should now be operational.

Indicator LEDs

The units have integral LEDs that are used to monitor the state of the unit.  Each unit has one power LED and one DATA LED, along with a VIDEO LED for each of the eight video connections.  The indicator LEDs function as follows:

TRANSMITTER and RECEIVER:

Data Cable Connections

The various input and output connections for the VERSITRON VersiVision FVTM880x and FVRM880x video transmission systems series are as follows:

Video Input or Output: BNC Connectors

Data RS-485 Connection:

Red Wire = (+) Signal being transmitted or received over fiber.
Blue Wire = (-) Signal being transmitted or received over fiber.

 
Camera Site

Connect the Red wire (+) in the data cable from the transmitter unit to the RS-485 (+) of the controlled unit (pan/tilt, dome), and connect the Blue wire (-) in the data cable to the RS-485 (-) of the controlled unit (pan/tilt, dome).

Control Site

           
Similarly, connect the Red wire (+) in the data cable from the receiver unit to the RS-485 (+) of the controlling unit (Keyboard Controller, Matrix, DVR), and connect the Blue wire (-) in the data cable to the RS-485 (-) of controlling unit (Keyboard Controller, Matrix, DVR).

TROUBLESHOOTING

Optical Fiber

The VERSITRON VersiVision FVTM880x and FVRM880x video transmission systems series is available for most applications using multi-mode or single-mode 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 connection to the camera(s), and then check whether the data cable connector is firmly connected to the unit.

If the system is still not working after examining the above possibilities, please contact our Customer Service Department for further assistance
