NOTE: VERSITRON uses the same front panel for multiple products.  Not all features are available on all models; therefore you should verify the features of your specific model.

The VERSITRON VersiVision FDVT101x and FDVR101x Series video/audio transmitter and receiver support simultaneous transmission of one channel of 8-bit digitally encoded video and one channel of forward audio over one multi-mode or single-mode optical fiber. The modules are universally compatible with major camera systems and Plug and Play design ensures ease of installation and electronic and optical adjustments are never required.

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 FDVT101x and FDVR101x video transmission systems series are preset for immediate use. There are indicator LEDs on the units for monitoring the real-time status of video 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 (FDVT101x) using coaxial cable.
  2. Connect the video output BNC connector on the receiver unit (FDVR101x) 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 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 one video LED and one power LED.  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)

        

*Front Panel of FDVT101x (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)

System Terminal Block Connections

The various input and output connections for the VERSITRON VersiVision FDVT101x and FDVR101x video transmission systems series are as follows:

Video Input or Output: BNC Connectorsa

 

 

Terminal No. 6: Ground

Terminal No 5: Audio

 

 

Camera Site

Connect the Terminal No.5 in the terminal block for audio connection to Channel 1 of the audio source, and Terminal No.6 in the terminal block to Ground.

Control Site

Connect the Terminal No.5 in the terminal block for audio connection to Channel 1 of the speaker, and Terminal No.6 in the terminal block to Ground.

TROUBLESHOOTING


Optical Fiber

The VERSITRON VersiVision FDVT101x and FDVR101x 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

Audio Link

Even when installed exactly as directed, it is possible that the audio function may fail to operate properly. If this problem occurs, first please check the audio connections, and then check whether the data cable connector is firmly inserted into the RJ-45 ports.

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