Serial Bus output from Serial Node Adapter to
J4 using shielded twisted pair cable, connecting
shield to GND terminal, (+) to (+) and (-) to (-). If
Serial Bus goes onto other motherboards, connect

Serial Digital Module - Installation
REMOTE I/O
Direct connection to Rockwell/Allen-Bradly
Remote I/O can be made via the Serial Node
Adapter or Serial Node Adapter +. Connect
the Allen-Bradley (AB) RIO cable directly to the
motherboard of the Node Adapter (78145-00 or
LECU4012). If the Serial Digital Module is in the
same motherboard as the Serial Node Adapter
(78145-00), no further connection is necessary.
If the Serial Digital Module is located in a differ-
ent motherboard (78147-00) the local serial bus
must be connected via the connector labeled
“Serial Bus”.
