Raymarine always recommends using the correct length Raymarine supplied cables with pre fitted connectors and the range of T Pieces and connectors available specifically for this purpose.
Whilst it is always best to avoid cutting and splicing communications cables - because every such join introduces a potential failure point; when it is essential, then as long as they are made carefully and correctly, it should not be a problem.

It is possible to use the appropriate type of waterproof plug and socket connector which can be fitted to the communications cables - usually available from a 3rd party - Raymarine do not supply self assembly plugs and sockets.

Alternatively the cable can be rejoined by soldering and heatshrink sleeving the cores, a few simple points to note here,
- The solder joint must be carefully made to ensure excellent conductivity across the join- that is to say no dry joints
- The sleeving must fully insulate the bares conductors
- The cable shield which encloses all the cores inside the cable MUST be reinstated to ensure correct shielding of the cable against RFi refer here for more information regarding RFi.
- the connection will need to be waterproof and provided with mechanical strain relief to avoid stress on the join
- The connection must be made in a dry protected location - if there is any concern for water ingress, then the joint should be further protected in a waterproof junction box
- A poor quality join will create data corruption and loss of data and may also trigger random data issues too.


NOTE: Fishfinder and Depth Transducer cables must not be modified / spliced.
