Appendix A: RJ-45 pin assignment and cable system

A.1 10/100Mbps, 10/100Base-TX
When connecting 10/100Mbps TP port to other devices, a straight or crossover cable
is necessary. The TP port of FT-807 supports auto-MDI detection. That means you
can directly connect the TP port to any Ethernet devices without making a crossover
cable. The following table and diagram show the standard RJ-45 receptacle/
connector and their pin assignments:
