1.0  Fiber Kit Installation Guide - –Single Mode fiber, LC-LC terminals – Assembly Instructions

1.1  Introduction

The Fiber kit system insert between the VPU and the CHU (camera head) and extend the installation distance limitation over coaxial cables (and analog cables for audio).

Basic scheme – fiber optics components and wiring

Basic schematics of the Coax prime system based on fiber kit – up to 20KM

1.2   Structure

The kit contains 2 Kaya’s components (LC-LC Single-mode):

A.   Coax to Fiber converter (Camera side)

B.    Fiber to Coax converter (Frame grabber side)

On the audio side, the kit contains 2 Ad-Net’s components (SC-SC single fiber):

A.   Analog to Fiber converter (Transmitter)

B.    Fiber to Analog converter. (Receiver).

1.3  Important Notice About the Kit

A.   Do not hot-plug the system! Connect the power to the units, only AFTER all the cables have already connected!!

B.    The installation should be carried out by certified technician, the connectors are sensitive, and requires Fiber optic knowledge prior the installation.

C.   Both kits have a directional flow, therefor, there is a major importance that the Coax to Fiber and Analog to Fiber located on the camera side.

The Fiber to Coax and the Fiber to Analog should be located on the VPU side.

D.   The channels order of the fibers is crucial, which means that CH0 from one converter, should be inserts to CH0 on the other converter.

So on for the rest 3 channels – CH0 to CH0, CH1 to CH1, Ch2 to CH2 and CH3 to CH3.

E.    Audio infrastructure – the audio fiber connection is over single fiber, with SC-SC termination (supplied).

1.4  Installation – Camera Side

The camera’s harness terminates with 4X HD-BNC connectors for the camera, and 1X RJ-45 connectors for the analog audio.

A.   Camera connections steps:

1)    Connect the 4 X Camera’s BNCs to the Female BNC-Din 1-2.3 extensions.

2)    Connect the DIN1-2.3 to the Coax to Fiber converter (camera side module).

3)    Insert the SFP’s to the 4 SFP’s slots (until it’s “clicked”).

4)    Connect the fibers (LC connectors).

5)    Connect the power supply (supplied 24VDC) make sure all cables are connected before connecting the power to the unit!

B.    Audio connections steps:

1)    Connect the male RJ45 of the camera to the Y splitter cable.

2)    Connect both XLR’s connector to the Behringer device (make sure the 48+ phantom power is set to “ON” at the back side of the Behringer device).

3)    Adjust the Gain volume input to 5-6 value for both inputs.

4)    Connect the Behringer outputs to the Audio to fiber inputs, using the PL-RCA cable.

5)    Make sure that the “Direct Monitor” button on the Behringer is pressed.

6)    Connect the SC fiber to the converter output and to the fiber infrastructure.

7)    Connect the power of the Behringer and of the Fiber converter (5VDC – USB power).

1.5  Installation – VPU Side

ON the VPU side, connect the fibers to convert the optic data to its original signals - Coax and analog audio.

A.   The coax cables and analog audio will be connected to the VPU.

1)    Insert the SFP’s to the 4 SFP’s slots (until it’s “clicked”)

2)    Connect the fibers (LC connectors)

3)    Connect the 4 X HD- BNC extensions to the Female BNC-DIN1-2.3 extensions – creating a cable as shown below.

4)    Connect the DIN1-2.3 to the “Fiber to Coax converter” (frame grabber module).

5)    Connect the 4 X HD-BNC of the extenders to the frame grabber in the VPU.

6)    No need for power supply connection, the unit gets the power from the Coax (port 0 on the converter)

B.    Audio connections steps:

1)    Connect the SC fiber to the receiver “Fiber to audio” unit

2)    Using the RCA to 3.5mm mini plug cable, Connect the 2 analog RCA to the converter.

3)    Connect the mini plug to the blue analog input in the VPU

4)    Connect the power to the converter unit (power supply or USB to DC cable)

C.   Operation notes

At this stage, the system is connected and should get Coax signals from the cameras and analog audio from the microphones.

•     The VPU is getting the audio from the “Default device” as configured in the system.

Make sure that the analog inputs are configured as default on the PC.

•     As the basic manual of the Coax Prime system, opening the “Vision Point” app, and pressing the camera icon, should initiate a process of connecting to cameras.

More on that in the basic connection manuals.
