RJ45 Ethernet Cable Wiring
For RJ45 connectors, data-quality, twisted pair cabling (rated CAT5 or better) is rec-
ommended. The connector bodies on the RJ45 Ethernet ports are metallic and con-
nected to the GND terminal. For best performance, use shielded cabling. Shielded
cabling may be used to provide further protection.
*Maximum cable length: 100 meters for 10/100BaseT.
