•
If “Yes” is selected, the Driver488/DRV command line will be added to the beginning of your
AUTOEXEC.BAT file.
•
If “No” is selected, no changes will be made to the AUTOEXEC.BAT file.
•
If “Manually” is selected, you can choose where the Driver488/DRV command line is to be added
in your
AUTOEXEC.BAT file.
After modifying the AUTOEXEC.BAT file, the installation program automatically invokes the
configuration program: CONFIG . You may also run CONFIG from the command line at a later time to
modify your configuration as required. Note if any error messages display when you are trying to load
DRVR488.EXE in memory, If so, refer to “Section IV: Troubleshooting” in this manual.
Configuration Utility
The configuration utility permits you to specify the Driver488/DRV system configuration, add
interfaces, define external devices, etc. It does so by modifying the Driver488/DRV startup
configuration specified in a Windows-style initialization file named
DRVR488.INI . The first screen of
the CONFIG program is used to enter the configuration settings so the Driver488/DRV software can be
correctly modified to reflect the state of the hardware.
The driver can be reconfigured at any time by running the CONFIG program. Changes to the
configuration will not be recognized by the driver until the driver is unloaded and reloaded. Typically,
this is accomplished by rebooting your computer or using the utilities
MARKDRVR and REMDRVR . For
details on these utilities, refer to the “Utility Programs” Sub-Chapters found in Chapters 8 and 9 in this
manual.
To start the CONFIG program, type CONFIG within the directory in which the configuration utility
resides, typically C:\IEEE488 .
Interfaces
The minimum requirement for configuring your system is to make certain that your IEEE 488.2
interface board or module is selected under “Device Type.” The default settings in all of the other
fields match those of the interface as shipped from the factory. If you are unsure of a setting, it is
recommended that you leave it as is.
External Devices
The CONFIG program can configure both interfaces and external devices. Interfaces are IEEE interface
boards and serial ports. External devices are instruments or other devices attached to the IEEE 488 bus
or the MP488(CT) Counter/Timers and Digital I/O devices. For more details, refer to the topic
“Configuration of IEEE 488 External Devices” found later in this Sub-Chapter.
Opening the Configuration Utility
In general, all Driver488/DRV configuration utility screens have three main windows: the “name” of
the interfaces or devices on the left, the “configuration” window on the right, and the “instruction”
window at the bottom of the screen. Based on current cursor position, the valid keys for each window
will display in the Instructions box.
To begin the interface configuration, move the cursor in the name window to select an interface
description for modification. (Interfaces can be added or deleted using
and .) Notice
moving the cursor up and down the list of interfaces or devices in the left window changes the
parameters in the configuration window. The configuration fields always correspond with the currently
selected interface and device type.
Once all modifications have been made to the configuration screen, must be pressed to accept
the changes made or can be pressed to exit without making any change. Additional function keys
