Installation and Operation Manual Appendix A IR-ETH Ethernet Card

ASM-40CD Ver. 1.0 Installation and Operation A-5

Installing the Hub

 To install LRSI-F-14:

1. Insert the LRSI-F-14 module into the upper section of the LRS-24F chassis

above the ASM-40CD module, or into the back section of LRS-24B.

2. Fasten the screws to secure the module to the LRS-24 frame for proper

grounding of the module panel.

Connecting the LRSI-F-14 Module

Table A-2

lists the pinout of the DCE-1/DCE-2 connector of the LRSI-F-14

interface module.

Table A-2. DCE-1/DCE-2 Connector Pinout

Pin ID Function Direction

1 Tx+ Transmit – positive lead Output

2 Tx– Transmit – negative lead Output

3 Rx+ Receive – positive lead Input

4, 5 – Not connected –

6 Rx– Receive – negative lead Input

7, 8 – Not connected –

When connecting LRSI-F-14 to the LAN, use a cross cable for connection to a port

that does not implement the crossover function internally. Otherwise, use a

straight cable.

•

To ensure compliance with electromagnetic compatibility (EMC) requirements,

use only shielded cables when connecting the DTE ports to the LAN.

•

Hubs usually do implement the crossover function internally while NICs and

other devices do not.
