2.4 Installing the Interface Module

Interface Module Inspection

Check that the supplied interface module meets the physical and electrical

interface requirements of the installation site, according to

Table 2-3.

The

interface modules are:

• LRSI-F-5 – V.24/RS-232 (64 kbps), V.35, X.21, RS-530 and V.36 interfaces

(via adapter cables), see

Figure 2-2

• LRSI-F-14 – IR-ETH, IR-ETH/QN, see

Figure 2-3

For a more detailed description of the IR-ETH and IR-ETH/QN interface modules,

see

Appendix A

and

Appendix B

LRSI-F-xx interface modules are placed in the top section of the LRS-24F chassis;

LRSI-B-xx interface modules are placed in the back section of the LRS-24B

chassis.
