Setting the Switches

Data Communications Module, 2nd Edition, 2/03
On the front of the unit, just to the left of the LEDs,
you’ll notice a small slide switch. This switch is
labeled ON (for online) and OFF (for offline). If you
want to communicate through the D2–DCM, make
sure this switch is in the ON position.
In the OFF position, this switch logically
disconnects the D2–DCM from the network (just
as if you pulled the cable from the connector).
Once this switch is moved to the OFF position, the
D2–DCM will not communicate with the network. If
you move the switch to the ON position, the
D2–DCM will communicate with the network, but
not until the master sends another request for
communication. This does not operate like the
reset switch on many personal computers.
