Hardware Setup
If using a DaqBook/200, DaqBook/216, DaqBoard/200A, or DaqBoard/216A that has a
serial number of 103350 or earlier, you must contact the factory for a hardware
upgrade (EO-1911) before using the DBK4.
Software calibration for each DBK4 requires a set of unique constants supplied on a
diskette identified by a serial number matching the DBK4 card. To install these
constants, follow instructions on the “readme” file included on the calibration disk.

Both hardware and software are used in configuration. This section focuses on the hardware. Jumpers and
switches are used to set:
current source (current level and source enable/disable) , filter bypass , signal
coupling , and channel addressing . It is best to remove power from the card to perform these selections.
The figure reveals the jumper and switch locations.
Note: The hardware jumper settings referenced in the following subsections are per-channel selections
unless otherwise specified.
