Ethernet #1 and #2

An 8-way, RJ-45 connector provides a 10BaseT

Ethernet interface for communications with the MEM

for control and monitoring. The Encoder has a single

switched Ethernet channel. Ethernet#1 is selected as

default at power-up. If a carrier is not detected on

Ethernet#1 then the input switches to Ethernet#2.

This gives a redundant Ethernet control via two hubs.
