A.2 Connection Data for ETH Electrical Ports
Each ASMi-54C ETH electrical port has a 10/100BASE-TX Ethernet interface
terminated in an RJ-45 connector. The port supports the MDI/MDIX crossover
function, and therefore it can be connected by any type of cable (straight or
crossed) to any type of 10/100BASE-TX Ethernet port. The port also corrects for
polarity reversal in the 10BASE-T mode.
Connector pin functions for the MDI state are listed in
Table A-2 . In the MDIX
state, the receive and transmit pairs are interchanged.
Table A-2. ETH Connector, Pin Functions
Pin Designation Function
1 TxD+ Transmit Data output, + wire
2 TxD– Transmit Data output, – wire
3 RxD+ Receive Data input, + wire
4, 5 – Not connected
6 RxD– Receive Data input, – wire
7, 8 – Not connected
