Use cable ties so nothing will come loose due to vibrations
Interface:
Ground Unit
Ground power cable shield
Use cable markings
Use bolt, washer and nut when mounting
Use wire markings
Groundings:
Always ground all units and power cables with ground wire. It is especially important when units are mounted on wood, plastic or other non-conductive material. For power cables, use ground wire in cable and also cable shield.
If grounding NMEA cables:
-
Best: ground the transmitting end of the cable only
-
Next-best: ground the receiving end of the cable only
-
Worst: ground both ends of the cable
Networks:
A-A: The T-568A standard is supposed to be used in new network installations. Most off-the-shelf Ethernet cables are still of the T-568B standard, however, it makes absolutely no functional difference which one you choose.
B-B: Both the T-568A and the T-568B standard Straight-Through cables are used most often as patch cords for your Ethernet connections. If you require a cable to connect two Ethernet devices directly together without a hub or when you connect two hubs together, you will need to use a Crossover cable instead.
A-B: A good way of remembering how to wire a Crossover Ethernet cable is to wire one end using the T-568A standard and the other end using the T-568B standard. Another way of remembering the color coding is to simply switch the Green set of wires in place with the Orange set of wires. Specifically; switch the solid Green (G) with the solid Orange, and switch the green/white with the orange/white.
