How Do DBKs Connect to the Data Acquisition Device?
Each DBK connects to the primary data acquisition device; e.g., a DaqBook, DaqBoard, or LogBook,
through one of three 37-pin ports, which are designated as follows:
Depending on the primary data acquisition device, connectivity issues differ slightly. This will be made
clear by the figures and accompanying text that follow.
For DaqBooks, ISA-Type DaqBoards, and LogBooks, DBK connections are not made directly to the port,
but through a CA-37-x ribbon cable, where "x" indicates the number of expansion devices that can be
connected. For example, in addition to providing a DB37 connector to interface with the primary data
acquisition device, a CA-37-3 cable includes three additional DB37 connectors. These provide a means of
adding three DBKs to one port. Use of a CA-37-16 cable will allow up to 16 DBKs to be added. The
CA-37-x cable system is excellent for DaqBooks, LogBooks, and ISA-type DaqBoards.
The above figure applies to LogBooks, DaqBooks, and ISA-type DaqBoards. As will be seen elsewhere in
the documentation, some models do not include all three connectors (P1, P2, and P3).
