DaqBook/2000 Series and DaqBoard/2000 Series Configuration
No jumper configurations are required for the /2000 series devices.
Software Setup
The DBK80 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 DBK80 with that board you will have the same Type options,
since the DBK80 is always a constant gain of x1.
Note that there is no software control related to the excitation source. The selection of a +5 VDC or
+10 VDC source is determined by JP2.
