2.1.3 FILE DEFAULT LOCATION
InstaCal will place all appropriate files in "C:CB" If you change this default location remember
where the installed files are placed as you may need to access them later.

2.1.4 INSTALLATION QUESTIONS
At the end of the installation process the installation wizard will ask a series of questions regard-
ing updating your startup files. Unless you have knowledge to the contrary, simply accept the
default (YES) when prompted. You will also be asked if you would like to read an updated
README file. If possible, please choose yes and take a look at the information in the file. It will
include the latest information regarding the software you are installing.

2.1.5 INSTALLATION COMPLETION
After the installation of InstaCal is complete you should restart your computer to take advantage
of changes made to the system.

2.1.6 DOS and WINDOWS 3.x
Most users are now installing PCI Bus boards in systems with Windows operating systems (e.g.,
Windows 95, 98 or NT). If you are using Windows 3.x, the setup wizard will automatically
install the 16-bit version of the Universal Library and InstaCAL. These versions are compatible
with the DOS operating system.

If you need to install the software and do not have access to Windows, you will need to order the
special "DOS Only" version of the software. The part number for these products are
INSTACAL/DOS and Universal Library/DOS. Please contact the factory if you have any
questions regarding these special DOS only versions.

3.0 Insta

Cal

InstaCal is the Installation, Calibration and Test software supplied with all I/O
boards. After installing InstaCal you should re-start your computer to take advantage of changes
made to the AUTOEXEC and CONFIG files. The PCI-DAS1602/16 does not have to be installed
in order for InstaCal to run, but must be in order to test or calibrate the board.

3.1 System Requirements

Two versions of InstaCal are supplied with the PCI-DAS1602/16. The standard 32-bit version is
compatible with Windows 95, 98, NT and greater. For those using older operating systems, the
DOS based, 16-bit version is supplied and is compatible with DOS, Windows 3.x and Windows
95 (though we recommend Windows 95 users take advantage of the 32-bit version).
