Twisted Pair Connectors and Cables
There are many types of cables and connectors that you can use to link your 10BASE-T Module to your network. These cables and connectors are explained in the following sections. Use this information to ensure that the cables and connecting hardware meet requirements. For proper operation, use only approved cables when you install all equipment. This section is divided into the following parts:

Twisted Pair Connectors
The IEEE 802.3 10BASE-T standard for pin-outs must be used. The following cable standard must be used. 10BASE-T uses 2 pairs of wire: pins 1 & 2 and pins 3 & 6. If the pairs are not configured this way, the connection will not work properly. Datagrade cable should have the following pin pairings:
❑pins 4 and 5 are pair 1
❑pins 3 and 6 are pair 2
❑pins 1 and 2 are pair 3
❑pins 7 and 8 are pair 4
