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.

&$87,21

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.

&$87,21

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

Verify DaqBook’s power switch is in the “

” (

OFF

) position.

Connect the female-end of the supplied cable to DaqBook’s connector labeled, “

FROM PC PARALLEL PORT

.”

Connect the male-end of the cable to an available parallel port on the PC.

Connect the supplied AC-to-DC adapter’s jack-end to DaqBook’s

POWER IN

connector.

Connect the adapter’s plug to a standard AC outlet.
