DBK32A Power Supply Card

The DBK32A provides added power in configurations where the number of expansion cards exceeds the
power available from a LogBook, DaqBook, or DaqBoard. For power, the DBK cards rely on voltages
supplied via the P1 connection. The DBK32A supplies ±15 V @ 500 mA via the P1 bus and is compatible
with all analog DBK cards.

The DBK32A does not provide +5 V. If +5 V is required by the DBKs in use, you should use the
DBK33 Triple-Output Power Supply. Refer to the DBK33 Document Module for additional
information.

Configuring the Primary Device for use with a DBK32A

Configuration for:

DaqBook/100 Series
DaqBook/200 Series
DaqBoard/100 Series
DaqBoard/200 Series [ISA-type boards]

CAUTION

You must configure the DaqBook/100 Series & /200 Series devices or DaqBoard
[ISA type] before connecting the DBK32A. Do not connect the P1 cable without
first removing the shunt jumpers from JP1 inside the DaqBook/100 Series & /200
Series device or DaqBoard [ISA type]. Failure to remove these jumpers can result
in damage to the DBK32A and the DaqBook/100 Series, DaqBook/200 Series or
DaqBoard [ISA type].

CAUTION

Using a DBK32A requires you to entirely remove the shunt jumpers from header JP1 inside the
DaqBook /100 Series & /200 Series or DaqBoard [ISA type], as shown in the figure. DaqBooks/100
Series & /200 Series and DaqBoards [ISA type] are shipped with these shunts positioned to deliver
analog power to P1.

Do not place jumpers on the -OCTOUT and -OCKLIN pins.
If configured such, damage to the 8254 timer chip will result.

JP1 default position will not work with a DBK32A. Shunt jumpers must be removed
before connecting DBK32A. See previous Cautions.

Configuration for:

DaqBook/260
DaqBook/2000 Series

No hardware configuration is performed in regard to using the
DBK32A with these devices.

DaqBoard/2000 Series
DBK60
LogBook/300
LogBook/360

Configuration for:

DBK41

When a DBK32A is installed in a DBK41, the DBK41 should have its JP1
jumper in the “ENABLE +5 VDC” position. Refer to the DBK41 section
of the manual for additional information.
