Connecting the D8128D to the Control/Communicator Using Molex Connectors

Each D8128D module is supplied with a 12-inch female-to-female molex cable assembly.
P1 and P2 are Molex connectors which parallel the COM, IN, OUT and +12 VDC terminals on the terminal strip.
In installations where there are multiple D8128Ds in use, you can use these connectors (as opposed to
terminals) with the supplied cable instead. However, when connecting D8128D modules directly to the panel, the
terminal strip may be easier to use.
The molex connectors provided are "keyed." This means that the molex plug can only fit in one direction.
However, to be sure the connector is attached correctly, make sure the red wire is on the bottom of P1 (or P2)
and the black wire is on the top.

When connecting multiple D8128Ds to a control/communicator, you may connect the control/communicator
terminals to P1 on the first D8128D and then connect P2 of the first D8128D to P1 of the second D8128D and so
on.
