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.
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:

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:

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.
