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 FVTM4B0x and FVRM4B0x 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 (FVTM4B0x) using coaxial cable.
  2. Connect the video output BNC connector on the receiver unit (FVRM4B0x) 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
Video: OFF

Indicates no video detected on input BNC connector
(No Video present on input BNC)

Video: ON

(Blue) Indicates video detected on input 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.

*Terminal Block for Data Connection

Camera Site

Channel 1
Connect the Terminal No.1——1 in the terminal block for data connection to RS-485 (+) of the controlled unit (pan/tilt, dome), and connect the Terminal No.2——2‚ in the terminal block to RS-485 (-) of the controlled unit (pan/tilt, dome).

Channel 2
Connect the Terminal No.3——3 in the terminal block for data connection to RS-485 (+) of the controlled unit (pan/tilt, dome), and connect the Terminal No.4——4 in the terminal block to RS-485 (-) of the controlled unit (pan/tilt, dome).

Control Site

Channel 1

Similarly, connect the Terminal No.1——1 in the terminal block for data connection to RS-485 (+) of the controlling unit (Keyboard Controller, Matrix, DVR), and connect the Terminal No.2——2‚ in the terminal block to RS-485 (-) of the controlling unit (Keyboard Controller, Matrix, DVR).

Channel 2

Similarly, connect the Terminal No.3——3in the terminal block for data connection to RS-485 (+) of the controlling unit (Keyboard Controller, Matrix, DVR), and connect the Terminal No.4——4„ in the terminal block to RS-485 (-) of the controlling unit (Keyboard Controller, Matrix, DVR).

TROUBLESHOOTING


Optical Fiber

The VERSITRON VersiVision FVTM4B0x and FVRM4B0x 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
