We are using a CAT6 Cable for transmitting power! Couple of reasons

1) It has 8 wires in one cable! 

2) The wire size is good enough to transmit 0.5A of current, enough for most of our devices. 

3) Cheap and available easily anywhere. 

4) Wire colors are all standard, so easy to communicate. 

We use a Wire Terminal block to make our connections on the submarine side. 

A schematic of the connections is available in pdf here.

The connections of the CAT6 Cable ( coming from the remote, left of this image). 

The 8 wires are split as Set A and Set B. 

Set A consists of the green and blue pairs

Set B consists of the Orange and Brown Pairs

In Set A the Connections are as follows in the table below. 

In Set B the Connections are as follows in the table below. 

A piece of CAT 6 cable, about 2 ft long is cut, and as shown below the Set B terminal block has connections to the thrusters. The wire originates from the submarine, comes out of the water tight compartment, and connects to the thrusters at the back of the submarine. 

We will cover the connections of the remote in a future log.
