4.2 WIRING FOR MULTIPOINT CIRCUITS
The Model 1050 supports
4.2.1 DAISY CHAIN TOPOLOGY
Using a daisy chain topology, you may connect as many as 10 Model 1050s together in a master/slave arrangement. 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.
Figure 3 (below) shows how to wire the two-pair cables properly for a Model 1050 daisy chain topology. Note that the ground connection is not needed.

Figure 3. Model 1060 daisy chain wiring
In a multipoint topology, you must configure the master Model 1050's carrier control strap differently than those of the slave Model 1050(s). Here are the proper carrier control strap settings for a daisy chain topology:
Function | Carrier Control Strap Setting |
Master | Carrier “Constantly ON” (pegs 2 & 3) |
Slave(s) | Carrier “Controlled by RTS” (pegs 1 & 2) |
