Configuring the DT9850 Series Device Driver
Note: In Windows 7, Windows 8, and Vista, you must have administrator privileges to run
the Open Layers Control Panel. When you double-click the Open Layers Control Panel icon,
you may see the Program Compatibility Assistant. If you do, select
Open the control panel
using recommended settings . You may also see a Windows message asking you if you want
to run the Open Layers Control Panel as a "legacy CPL elevated." If you get this message,
click
Yes
.
If you do not get this message and have trouble making changes in the Open Layers Control
Panel, right click the DTOLCPL.CPL file and select
Run as administrator . By default, this file
is installed in the following location:
Windows 7, Windows 8, and Vista (32-bit)
C:\Windows\System32\Dtolcpl.cpl
Windows 7, Windows 8, and Vista (64-bit)
C:\Windows\SysWOW64\Dtolcpl.cpl
To configure the device driver for the DT9850 Series module, do the following:
1. If you have not already done so, power up the host computer and all peripherals.
2. From the Windows Start menu, select Settings|Control Panel .
3. From the Control Panel, double-click Open Layers Control Panel .
The Data Acquisition Control Panel dialog box appears.
4. Click the DT9850 Series module that you want to configure, and then click Advanced .
5. Click the Digital Input Mask tab to select the digital input lines that you want to enable
for interrupt-on-change detection, where bit 0 corresponds to digital input line 0, bit 1
corresponds to digital input line 1, and so on. When any of the enabled digital lines
changes state, the module reads the digital input value and generates an interrupt to alert
your application about the change of state. Refer to
page 60 for more information on
interrupt-on-change operations.
6. By default, power is continuously applied to the module even when applications that use
the module are terminated; this ensures that all outputs remain constant. However, if you
need to conserve power (especially when using a laptop), you may want to turn off power
to the module when an application terminates its connection to it. Note, that in this case,
the output values will float when the application terminates.
To turn power off to the module when an application terminates its connection to it, click
the
High Power tab, and click the Power Off on termination checkbox. High-power
circuitry on the module will be powered down when you exit from applications that use
the module. The module will remain off until you either run an application that uses the
module or uncheck the
Power Off On Termination checkbox.
7. Click OK .
