Chapter 2 Installation and Configuration
© National Instruments Corporation 2-7 PC-OPDIO-16 User Manual
With this option, you can create multiple configuration files for different NI-DAQ applications
or projects; simply use the appropriate path name when you want to create a new configuration
file or view an existing one. Be sure to enter only the path name; the file will automatically be
created as ATBRDS.CFG in the specified directory.
When you run an NI-DAQ DOS application, NI-DAQ will look for the configuration file in the
current directory first. If NI-DAQ cannot find ATBRDS.CFG, it will look in the root directory of
the current drive. NI-DAQ will also read the device configuration that was stored in the EISA
system configuration utility.
DAQCONF takes a long time to start up. If you are not planning to use switchless devices with
NI-DAQ, you can start DAQCONF with the -x command-line option. This will disable auto-
detection of switchless devices in your computer.
Device Configuration in DAQCONF
DAQCONF opens with the board configuration panel. Perform the following steps to configure
your board.
1. Select a Device Number for your device. Use the F5 and F6 keys to scroll through the
choices. If the device number selected has a device assigned to it, you will see the current
settings for that device. To add a device, select a number without any device assigned to it.
You will use the device number in your NI-DAQ function calls to identify which device you
want to use.
2. Use the down arrow key to highlight the Device selection. Use the F5 and F6 keys to find
the correct device type.
3. You need to select the correct I/O base address. Use the up/down arrow keys to highlight the
fields, and then use the F5 and F6 keys to select the settings you wish to use.
4. You must save the configuration for this device before advancing to the next device number.
Press F10 to save. DAQCONF will test the configuration parameters before saving. If the test
fails, DAQCONF will not save the settings. You can disable the automatic test feature by
using the -t option on the command line when you invoke DAQCONF as in the following
example:
DAQCONF -t
