This configuration requires the KF3 and three link couplers:
one SLC 500 family controller is connected to each of the link couplers
with a 1747-C11 cable
the KF3 is connected to the network at one of the link couplers
the DH-485 cable consists of three segments of cable daisy-chained to
the link couplers and the KF3
The connection between the first node (the KF3) and the link coupler to the
second node is shown in Figure 2.7.
