Connecting the Camera Unit cables
You must connect the fourth wire to the Camera Unit. The fourth-wire cable connects the Camera Unit to the Communication Hub inside the Trawl Unit. The fourth wire is terminated by a Y-split cable, which connects to sockets on the camera and lamp.
Prerequisites
•  Spiral bundling wrap to protect cables
•  Fine mesh netting
•  Dow Corning® 4 electrical insulating compound
Context
The Camera Unit is the assembly that contains the underwater monochrome camera and the powerful LED lamp.
Note
There are several Camera Unit models available — the North American and European models are shown here.

Procedure
1 Connect the single end of the Y-split cable to the connector at the end of the fourth-wire cable.
2 Connect the two Y-split cable connectors to the sockets on the camera and the lamp, and make sure they are properly fastened.
Caution
Grease the cable connector plugs with a light coating of insulating compound before mating. The 8-pin connector on the camera is fragile! Make sure you do not twist the connector when mating.

3 Install an appropriate spiral bundling wrap on the cables to protect them from chafing.
4 Position and lock down the cable-relief blocks on the frame (!).
5 Set the camera and lamp tilts and lock them down securely.
6 You may wish to wrap the entire frame in fine mesh netting to keep the fish out.
