1784-PKTX or -PKTXD card and three link couplers:
• An SLC family CPU is connected to each of the link couplers (1747-
AIC) with a 1747-C11 cable.
• The 1784-PKTX or -PKTXD card is connected to the network at one of
the link couplers, as shown in Figure 4.1.
• The communication cable consists of three segments of cable daisy-
chained at each link coupler.
