Configure the NI-488.2 Software
You can use
wibconf
to view or change the configuration of the NI-488.2
driver. If you installed more than one GPIB-1284CT, or if your single
GPIB-1284CT is not connected to
lpt1
, you must configure the NI-488.2
software with
wibconf
.
To run
wibconf
, complete the following steps:
1.
In the GPIB group of Program Manager, double-click on the
wibconf icon.
2.
Type the drive, path, and name of the GPIB configuration file, usually
c:\windows\gpib.ini
.
3.
Click on the OK button.
4.
Use the cursor keys to select different fields and view corresponding
help information.
5.
(Optional) Configure the NI-488.2 driver.
If you know the type of your parallel port, set the Type of parallel port
field to the correct type—UNIDIR, BIDIR, or EPP. All parallel port
types support the unidirectional protocol, UNIDIR.
Note
If you have a PS/2 computer, set the Type of parallel port field in
wibconf
to
BIDIR.
Note
The NI-488.2 driver does not safely detect an EPP parallel port at I/O address
0x3BC. If the parallel port is at I/O address 0x3BC and the Type of parallel port field is
set to AUTO, the driver detects a unidirectional port.
6.
To save your changes and exit
wibconf
, press <Esc> or <F9>. For the
changes to take effect, you must restart all of your Windows GPIB
applications.
After you install and configure the software, continue to Chapter 4,
