IR-ETH Ethernet Card
D.1 Introduction
The IR-ETH Ethernet card is a bridge that converts Ethernet electrical levels to
TTL levels and Ethernet protocol to HDLC protocol. It provides long distance
transmission and avoids the Ethernet collision limitation. It is mounted on the
ASMi-52CD modem module, installed in the LRS-24 hub.
Typical Application
A typical application of the ASMi-52CD module, on which the IR-ETH Ethernet card
is mounted, is shown in
Figure D-1.
The LAN connection is made by using the
LRSI-F-14 Interface module installed in the upper section of the LRS-24F chassis,
or LRSI-B-14 installed in the back section of the LRS-24B chassis.
