Ethernet Connections
Ethernet 8-Pin 10Base-T Connector (Port 1)The Ethernet connector is an RJ45, 10Base-T connector. The pin-out for the connector is shown below:
Pin | Pin Name |
| |
1 | Tx+ |
| |
2 | Tx- |
| |
3 | Rx+ |
| |
4 | not used by 10Base-T |
| |
5 | not used by 10Base-T |
| |
6 | Rx- |
| |
7 | not used by 10Base-T |
| |
8 | not used by 10Base-T |

When to use straight-through and cross-over cable:
•ENI Ethernet port to 10Base-T Ethernet switch cables utilize a straight-through pin-out (1-1, 2-2, 3-3, 6-6).
•Direct point-to-point 10Base-T cables connecting the ENI Ethernet port directly to another ENI Ethernet port (or a computer 10Base-T port) require a cross-over pin-out (1-3, 2-6, 3-1, 6-2).
