Gigabit Ethernet

The CP-RIO3-42 board includes two 10Base-T/
100Base-TX/1000Base-T Ethernet ports.

The Ethernet connectors are realized as RJ45 con-
nectors, but without operational status LEDs. The in-
terfaces provide automatic detection and switching
between 10Base-T, 100Base-TX and 1000Base-T
data transmission (Auto-Negotiation). Auto-wire
switching for crossed cables is also supported (Auto-
MDI/X).

RJ45 Connector J10A/B Pinouts

The J10A/B connector supplies the 10Base-T,
100Base-TX and 1000Base-T interfaces.
