When to use straight-through and cross-over cable:
• MicroLogix 1100 Ethernet port to 10/100Base-T Ethernet switch
cables utilize a straight-through pin-out (1-1, 2-2, 3-3, 6-6).
• Direct point-to-point 10/100 Base-T cables connecting the MicroLogix
1100 Ethernet port directly to another Ethernet port (or a computer
10/100Base-T port) require a cross-over pin-out (1-3, 2-6, 3-1, 6-2).
