MULTI-FUNCTION LD CARD
4.6 Multipoint Applications
The Multi-Function LD Card supports multipoint applications using
equipment arranged in a star topology. Maximum distance between the units
will vary based on the number of drops, data rate, wire gauge, etc. Call your
supplier’s technical support for distance estimates more specific to your
application. Figures 4-3 and 4-4 below show how to wire two-pair and one-pair
cables respectively for a Multi-Function LD Card star network.
