Gigabit Ethernet Interfaces
The CP-RIO3-04S provides one dual Gigabit Ethernet
connector J10A/B realized as two RJ-45 connectors.
The interfaces 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 sup-
ported (Auto MDI-X).
