Measurement Computing DBK Part 2 - Manual (Page 138)

Tip: Label each transducer with its associated channel/sub-channel information.
2.
For a single DBK65 module, connect one end of the P1 cable to the module’s male DB37 output
connector.
For DaqBook applications - use a CA-37-1, or a CA-255-xT cable.

•
For DaqBoard/2000 Series applications - use a CA-37-1 with a DBK200 Series adapter.
For DaqBoard [ISA type] boards - use a CA-131-1 cable.
3.
Connect the free end of the cable to the P1 port of the LogBook or Daq device. For multiple DBK65
modules, use a CA-37-x, CA-131-x, or a CA-255-xT cable to daisy-chain several modules or an
expansion module. For example, three DBK65s could be connected to a LogBook or a Daq device
with via a CA-37-3 cable.
Connecting to a BNC Connector (Used with WaveBooks and ZonicBooks)
To connect a BNC connector to a DBK65 channel as signal input we make use of the two-wire scenario.
The positive wire comes from the BNC central pin and connects to a DBK65 channel SIG+ terminal. The
negative wire connects the negative of the pin hub to a DBK65 channel SIG- terminal. A “BNC to Male
Binding Post” connector is convenient for making such two-wire connections.

Software Setup
The DBK65 has no special software settings. The software controls are equivalent to those for a direct
connection; e.g., for a DaqBoard/2000 Series board there are Type selections of x1 to x64, representing the
internal gain of that board. When using the DBK65 with that board you will have the same Type options,
since the DBK65 is always a constant gain of x1.
LogView does not include the means to directly select a DBK65. To use a DBK65
with LogBook: First select DBK80 in LogView. This will recognize the DBK65, but
will identify it as a DBK80 (which has eight additional channels). Next do one of the
following as applicable:
(a) If the DBK65 is set to the L sub-address, use channels 0 through 7; and ignore
the displayed unused channels (8 through 15)
.
(b) If the DBK65 is set to the H sub-address, use channels 8 through 15; and
ignore the displayed unused channels (0 through 7)
.
