Channel Filter Jumper Settings for DBK50 and DBK51
The low-pass filters have a default corner frequency of 3.5 Hz when the jumpers are in the LPF-selected
positions. This frequency may be readily changed by installing a different value of SIP resistor network in
the 6-pin SIP socket of each filter section. Each channel has its own SIP located next to the channel filter
bypass jumper and labeled RN(1-8)01A. The table lists values of common networks and their corner
frequencies.

DaqBook/100 Series & /200 Series and DaqBoard [ISA type] Configuration
Several setup steps in DaqBook/100 Series & /200 Series devices and DaqBoards [ISA type] are required
to use a DBK50 or DBK51 module in a system.
1. If not using auxiliary power, set the JP1 jumper [in the DaqBook/100 Series & /200 Series
devices or ISA-Type DaqBoard] to the Analog Option Card Use, also referred to as the
expanded analog mode.
