Cable Diagrams
Data Communications Module, 2nd Edition, 2/03
These diagrams show the D2–DCM being used as the network master. The cable diagram is
the same when the D2–DCM is being used as a slave (for those connections that could have
the master/slave roles reversed). This is true for the:
S
D2–DCM to D4–DCM connection
S
D2–DCM to DL405 CPU connection when used with a D4–450
