3.2.3 Terrestrial Data Connector Group
3.2.3.1 J5 | DATA, J6 | DATA Connections, RJ-45F
DO NOT MIX products of different speeds (e.g., 10BaseT on J5, 100BaseT on J6, and
GigE on J7), or different duplex operation (e.g., half duplex on J5 and full duplex on
J7). Doing so can cause a degradation in speed/performance of the data link traffic.
The RJ-45 female J5 | DATA and J6 | DATA connections are auto-sensing, auto-
crossover ports used for 10/100/1000 BaseT Gigabit Ethernet data traffic.
The typical connector pinout is as follows:
Pin # Description Direction (I/O)
1 TRP1+ I/O
2 TRP1- I/O
3 TRP2+ I/O
4 TRP3+ I/O
5 TRP3- I/O
6 TRP2- I/O
7 TRP4+ I/O
8 TRP4- I/O
