Ethernet Cable for wiring sensors

There are two standards, so check the RJ-45 plug to see which standard the cable uses before wiring the sensor! Failure to check this could cause damage to the sensor

T-568A Straight-Through Ethernet Cable

green S+
white/orange ground
blue -5 V
white/blue +5 V
orange +10V
white/brown -15 V
brown +15 V

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 in which you choose.
