Connecting Expansion Boards to a Z-World
Controller
Use the 26-conductor ribbon cable supplied with an expansion board to
connect the expansion board to the PLCBus on a Z-World controller. See
Figure 6-2. The expansion boards two 26-pin PLCBus connectors, P1 and
P2, are used with the ribbon cable. Z-World recommends using the cable
supplied to avoid any connection problems.
Figure 6-2. Connecting XP8500 Expansion Board to Controller PLCBus
Be sure power to the controller is disconnected before adding
any expansion board to the PLCBus.
Follow these steps to connect an expansion board to a Z-World controller.
1. Attach the 26-pin ribbon cable to the expansion boards P2 PLCBus
header.
2. Connect the other end of the ribbon cable to the PLCBus port of the
controller.
Be sure pin 1 of the connector cable matches up with pin 1 of
both the controller and the expansion board(s).
3. If additional expansion boards are to be added, connect header P2 on
the new board to header P1 of the board that is already connected.
Lay the expansion boards side by side with headers P1/H1 and P2/H2
on adjacent boards close together, and make sure that all expansion
boards are facing right side up.
See Appendix C, Connecting and Mounting Multiple
Boards, for more information on connecting multiple expan-
sion boards.
