2.1.2 Gigabit Ethernet Interfaces
The CP-RIO3-05 provides two dual Gigabit Ethernet connectors J6 (ETH A / ETH B) and J7
(ETH C / ETH D) realized as two dual RJ-45 connectors. The interfaces provide automatic de-
tection and switching between 10Base-T, 100Base-TX and 1000Base-T data transmission (Au-
to-Negotiation). Auto-wire switching for crossed cables is also supported (Auto MDI-X).
Note ...
The Ethernet LEDs have no functionality on the CP-RIO3-05.
