ST.TM.E10076.3
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.

A 9-way, D-type male connector provides an alarm
relay interface which can be used to send a signal to
remote equipment.
