Quick Start Guide

For DaqBoard/100A, /112A, /200A, and 216A

This document does not apply to DaqBoard/2000.

Reference Notes: (1) Consult your PC owner’s manual as needed. (2) Be sure to read about the DBK cards and modules
applicable to your acquisition system. Specific DBK information can be found in your Daq User’s Manual (included on your
install CD-ROM). (3) The user’s manual contains power management, hardware, software, and program-related information.

&$87,21

Turn off power to the host PC and externally connected equipment prior to removing the PC’s cover and
installing a DaqBoard. Electric shock or damage to equipment can result even under low-voltage
conditions.

Take ESD precautions (packaging, proper handling, grounded wrist strap, etc.)

Use care to avoid touching board surfaces and onboard components. Only handle boards by their edges (or
ORBs, if applicable). Ensure boards do not come into contact with foreign elements such as oils, water, and
industrial particulate.

JP1 -

External Analog Expansion Power

&$87,21

Placing the jumpers on JP1’s 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.

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 figure.

JP2 -

DAC Reference Voltage and SSH (Simultaneous Sample and Hold)

&$87,21

In regard to JP2, the SSH jumper must be removed if you are using EXT DAC0 or EXT DAC1.
See users manual for details.

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 the JP2 jumpers at their factory default settings.
Consult the user’s manual prior to making changes.
