Introduction & Product Description
Chapter Objective
This chapter contains a description of the major hardware components of
the Multi-Communications Adapter board. It is not intended to be an all
encompassing technical description of each hardware component. This
chapter provides information to aid service personnel in:
S Identifing the MCA board.
S Understanding the hardware content of the board.
S Understanding the hardware requirements necessary to interface this
board with external devices.
General Board Description
The MCA board contains the hardware necessary to connect the
Drive to Allen-Bradley’s RIO or DH+ communication links. Once
connected, these links can be used to control, diagnose, and setup
the Drive. Figure 2–1 shows the major hardware components
located on this board. Refer to Figure 2–1 when attempting to identify
the various hardware components.
The MCA board contains a small interface board, referred to as
the Interface Plug, which contains the hardware necessary to
communicate to Allen-Bradley PLC controllers via RIO and\or DH+,
or to other devices via DH+. Refer to the installation section of this
manual for further details.
DIP switches U5 and U6 are used to select communication type,
baud rate, and rack or station number for channel A. Switches U14
and U15 perform the same function for channel B.
