4.3 FOUR-WIRE, MULTIPOINT INSTALLATION

Multipoint operation involves the connection of several terminals to one host port. In such an application, one local Model 1080A/1080A-64 is used as a master unit, and it is connected to several remote Model 1080A/1080A-64s that are acting as slaves. Up to 25 Model 1080A Series slaves may be connected to one host Model 1080A Series master SRM, provided that the computing hardware and software support that many terminal drops.

In a multipoint environment the master Model 1080A or 1080A-64 transmits continually. Initiation of two-way communication is carrier- controlled by each “slave” Model 1080A Series unit. To facilitate multipoint communication, the master Model 1080A-64 should have its carrier control DIP switch set to “constantly ON” (S1-8=OFF). Each slave Model 1080A Series unit should have its carrier control DIP switch set to “controlled by RTS” (S1-8=ON). Figure 4 illustrates a typical Model 1080A Series multipoint application.

4.3.1 Multipoint Twisted Pair Connection

The Model 1080A Series supports multipoint applications using a star topology. Maximum distance between the units will vary based upon the number of drops, data rate, wire gauge, etc. Call Patton Technical Support for specific distance estimates. Figures 11 and 12 show how to wire the one-pair and two-pair cables properly for a Model star topology. Note that the ground connection is not needed.
