JP1 - External Analog Expansion Power
If analog option cards (DBKs) are used, JP1 jumpers are set to provide
+15 and -15 VDC to the cards.
If using a DBK32A or DBK33 Power Supply Card, remove all jumpers from JP1.
If no cards are being used, the counter/timer CTR0 is available, and JP1 must be set as
shown in the right-side figure.

Placing the jumpers on -OCTOUT and -OCLKIN could damage the 8254 timer chip! If either a DBK32A Auxiliary Power
Supply or a DBK33 Triple-Output Power Supply Card is used, the JP1 shunt jumpers must be removed, otherwise timer chip
damage will occur. Refer to the DBK32A, DBK33, and Power Management sections of your user’s manual for more
information.
* Reference Notes: (1) DaqBook/260 is shipped with an additional instruction guide detailing the removal of its slide-out drawer and the
proper steps for installing internal cards. (2) DBK cards and modules are available for a variety of data acquisition functions. Specific DBK
information can be found in your Daq User’s Manual (CD, or hard-copy version). (3) Your CD contains power management, software, and
programming-related information.
JP2 - DAC Reference Voltage and SSH (Simultaneous Sample and Hold)
JP2 selects an Internal (default) or External reference voltage for the two separate analog outputs.
JP2 also selects SSH (default) for applications using one or more of the following:
DBK2, DBK4, DBK5, DBK7, DBK17, DBK50, or DBK51.
Leave these jumpers at the factory default. Consult the user’s manual prior to making changes.

Incorrect jumper placement can damage the DaqBook!
•
JP2 – If EXT DAC0 or EXT DAC1 are used, the SSH jumper must be removed! See users manual for details.
•
JP3 and JP4 - Placing JP3 [or JP4] jumpers horizontally can damage DaqBook!
JP3 - Bipolar or Unipolar A/D Operation
JP3 selects Bipolar (default) or Unipolar operation for the A/D converter.
•
If using DBK cards, leave these jumpers in the factory default positions.
• If you want 0-10V range [instead of –5 V to +5 V] and are not using DBK cards,
position JP3 jumpers to select Unipolar.
Note: For DaqBook/200, /216 and /260 a JP3 equivalent setting is made in software.
JP4 - Single-ended or Differential Analog Input Channels
JP4 selects the analog input lines as 16 Single-Ended channels (default);
or 8 pairs of Differential channels.
If using DBK cards, leave these jumpers in the factory default positions.
If you are not using DBK cards and you want differential channels, then position the jumpers for Differential.
Note: For DaqBook/200, /216 and /260 a JP4 equivalent setting is made in software.
(2) Connect PC
and
(3) Connect Power
1. Verify DaqBook’s power switch is in the “0” (OFF) position.
2. Connect the female-end of the supplied cable to DaqBook’s connector labeled, “FROM PC PARALLEL PORT.”
3. Connect the male-end of the cable to an available parallel port on the PC.
