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:
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).
