This chapter describes how to configure the DT9820 Series Device
Driver.
To configure the device driver, perform the following steps:
1.
If you have not already done so, power up the host computer and
all peripherals.
2.
From the Control Panel, double-click the Open Layers Data
Acquisition Control Panel
icon.
The Open Layers dialog box appears.
3.
Click the DT9820 Series function module that you want to
configure, then click Advanced.
The DT9820 Configuration dialog box appears.
4.
It is recommended that you select the 10k Ohm Resistor
Terminations
checkbox for each analog input channel on the
module. This ensures that 10 k
Ω
of bias return termination
resistance is used for the analog input channels. (This is the
default configuration.) Bias return termination resistance is
particularly useful when your differential source is floating.
5.
Select whether the DT9820 Series module will be used in 60 Hz
operations (the default), or 50 Hz operations (used primarily in
Europe).
6.
To continuously power the analog and/or digital outputs, select
the Power Always On checkbox. The DT9820 Series module will
remain on even when you exit from the applications that use the
module.
If you want to shut down power to the module, you must
uncheck this checkbox and close the control panel. Once all
applications that use this module are exited, the module will
power down. The module will remain off until you either run an
application that uses the module or click the Advanced button
from the Open Layers Data Acquisition Control Panel.
7.
Click OK.
