Patton electronic 1060 AC Powered user manual Wiring for Multipoint Circuits, Daisy Chain Topology

4.2 WIRING FOR MULTIPOINT CIRCUITS

The Model 1060 supports multi-point applications using either a star or daisy chain topology. Both topologies require special wiring, as well as specific DIP switch settings for master and slave units.

4.2.1 DAISY CHAIN TOPOLOGY

Using a daisy chain topology, you may connect as many as 10 Model 1060s 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 1060 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 1060's DIP switches differently than those of the slave Model 1060(s). Here are the proper DIP switch settings for a daisy chain topology:

Switch Number	1	2	3	4	5	6	7
Master Positions	ON	ON	ON	OFF	OFF	OFF	OFF
Slave Positions	ON	ON	ON	OFF	OFF	OFF	ON

4.2.2 STAR TOPOLOGY

Using a star topology, you may connect several Model 1060s 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 4 (below) shows how to wire the two-pair cables properly for a Model 1060 star topology. Note that the ground connection is not needed.

In a multipoint topology, you must configure the master Model 1060's DIP switches differently than those of the slave Model 1060(s). Here are the proper DIP switch settings for a star topology:

Switch Number	1	2	3	4	5	6	7
Master Positions	ON	ON	ON	OFF	OFF	OFF	OFF
Slave Positions	ON	ON	ON	OFF	OFF	OFF	ON

4.3 RS-232 CONNECTION

To connect the Model 1060 to a piece of data terminal or data communications hardware, use a straight through RS-232 cable. Plug the cable directly into the DB-25 port on the rear of the Model 1060. The DCE/DTE switches eliminate the need for a crossover cable.
