System Example

A DaqBoard/3000 Series system example which includes both a PDQ30 and a DBK215 is illustrated on
page 2-4. For convenience, it has been repeated below. In regard to the PDQ30 aspect:

1)

Connection from PDQ30 to DaqBoard/3000 is made via a CA-266-3 (or CA-266-6) HDMI cable.

2)

PDQ30’s analog input lines connect via removable screw-terminal blocks (TB1 through TB6).

3)

A pinout for PDQ30 follows shortly.

4)

Users of DBK215 should refer to Appendix A.

5)

Instead of connecting a DBK215 to the DaqBoard/3000 series 68-pin SCSI connector, a TB-100
terminal board option can be connected. The TB-100 option is discussed on page 2-3.

DaqBoard/3000 Connected to a PDQ30 and to a DBK215*

*Note

: The DBK215 offers screw terminal connections and BNC connections in an enclosure. If BNC connectors and an

enclosure are not needed, a TB-100 Terminal Connector option can be connected to the 68-pin SCSI connector instead
of the DBK215. See page 2-3 for TB-100 information. Refer to Appendix A for DBK215
information.
