Connection to Allen-Bradley DH+ and/or RIO networks is accomplished
through two connectors located on the bottom of the MCA board (Refer to
Figure 4–1). The first step is to determine what protocol will be used for
each channel. The next two sections explain how to connect RIO and DH+
networks to the Drive.

Switch Settings
The MCA Adapter contains 4 DIP switches which perform several
different setup functions. DIP switches U5 and U6 are used to select link
type, baud rate, and rack or station number for channel A. U14 and U15
perform the same function for channel B.
NOTE:DIP Switch orientation on the MCA board is as follows:
CLOSED = “ON” = “1”
OPEN = “OFF” = “0”
ON ON Off Off
