Hardware

Settings

Opens the Configure System Hardware window that lets you tell the software how the

hardware is set up. Setup sections include: Analog I/O Option Cards (DBKs), Digital

Option Cards, A/D Input Polarity, A/D Signal Reference, and D/A External Reference.

Options that do not apply to a particular device will be grayed-out when applicable.

Make sure the Configure Systems Hardware window is kept updated

according to the actual hardware being used.

Configure System Hardware

The Analog I/O Option Cards section lets you assign DBK expansion cards to the

16 analog input channels. If no expansion cards are added, leave the default value

(Direct Signal Connection) on all 16 channels. As expansion cards are added, this

window must be updated.

Selecting a DBK expansion board will add channels in the main window’s Analog &

Scanned Digital Inputs spreadsheet. Channels associated with DBK expansion

boards will also have their own gains or modes to choose from in the analog input

spreadsheet. If needed, a dialog box will appear and allow you to set sub-channel

addresses or other parameters.

If using the DaqBook/100, DaqBook/112, or DaqBook/120, set the radio buttons for

Single-Ended or Differential and Bipolar or Unipolar to match the settings of the

corresponding hardware jumpers (the default hardware settings are Single-Ended

and Bipolar). When Differential is selected, only 8 analog inputs are available.

When analog expansion boards are connected, set the Daq for Single-Ended.

If using the DaqBook/100, DaqBook/200, DaqBook/260, DaqBoard/100A,

DaqBoard/200A, a DaqBoard/2000 Series or a DaqBook/2000 Series device, the

Digital Option Cards section lets you configure the digital I/O hardware. If no

DBK20 digital expansion boards are connected, three 8-bit I/O ports are accessible

from the main window. Six additional 8-bit ports are made available in the main

window for each DBK20 added.

Depending on your primary data acquisition device, if you are using a DBK12,

DBK13, DBK15, DBK19, DBK52, DBK53, or DBK54 you may be prompted to

select an internal clock speed of 100 kHz.
