Appendix A

IR-ETH Ethernet Card

A.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

ASM-40CD modem module, installed in the LRS-24 hub.

Typical Application

A typical application of the ASM-40CD module, on which the IR-ETH Ethernet card

is mounted, is shown in

Figure A-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.
