8.7 Ethernet wiring
ColorLight searchlight systems should be connected to their own dedicated network; they
should never be connected into the vessels existing computer network.
An Ethernet cable supplied from ColorLight complies with the standard TIA/EIA-568-B and is
always tested together with the complete searchlight system to ensure full functionality.
If customers choose to assemble their own Ethernet cables they must be of type FPT Cat5 or
better and the connections should be done according to the following information.
Note that the only difference between T568A and T568B is that pairs 2 and 3 (orange and
green) are swapped. Both configurations wire the pins "straight through", i.e., pins 1 through 8
on one end are connected to pins 1 through 8 on the other end. Also, the same sets of pins
connect to the opposite ends that are paired in both configurations: pins 1 and 2 form a pair, as
do 3 and 6, 4 and 5, and 7 and 8.
One can use cables wired according to either configuration in the same installation without
significant problem. The primary thing one has to be careful of, is not to accidentally wire the
ends of the same cable according to different configurations
