Hardware Description
General
Chapter 2 contains a general description of the major hardware components
of the Digital Reference Adapter Board. It is not intended to be an all
encompassing technical description of each hardware component. This
chapter provides basic information to help you:
S Identify the Digital Reference Board input configuration.
S Understand the hardware requirements necessary to interface the Digital
Reference Board with peripheral devices.
The Digital Reference Adapter Board connects directly to the Main Control
Board using either Port A or Port B of the Microbus Interface (Figure 2.1).
This interface supplies the Adapter Board with all logic voltages and
communication capabilities. All user connections to the board are made at
Terminal Block TB-3 located at the bottom of the 1395 Drive. The Digital
Reference Adapter Board is shown mounted in the standard position in Port
A (left port) of a 1395 Drive in Figure 2.1.
