The DH-485 port can also be used by the module to connect the MVI56-BAS to a
DH-485 network. The DH-485 port is not directly DH-485 compatible, since it
requires an AIC+ module (AB) which is user-supplied.
The following shows an example application where the MVI56-BAS is connected
to a DH-485 network. In this example, the MVI56-BAS communicates with the
DH-485 port of a SLC 5/03 processor.
Important: The setup jumper (located at the bottom of the MVI56-BAS module) must be OFF in
order for DH-485 communications to work properly.
