Important: If you are connecting the 1784-PCMK card directly
to an SLC 5/01, 5/02, or 5/03 processor, your
DH485 link can have only two nodes, the
SLC processor and the notebook computer with the
1784-PCMK card installed. Connect the
1784-PCMK card through a 1747-AIC link coupler
to use the 1784-PCMK card on a DH485 link with
more than two nodes.
