6. When prompted for a destination directory, enter the desired installation directory.
By default this directory is c:\lonworks, unless previous LONWORKS
products
have been installed and registered a different path in the Windows Registry. The
path may be modified using the Browse button; however, if a directory other than
c:\lonworks is chosen, the PCLTA-20 images path will have to be specified to
enable use of the PCLTA-20 card. This is accomplished during PCLTA-20
Configuration. See Chapter 3, Configuring and Testing the PCLTA-20 Adapter.
7. There is a limit of six (6) PCLTA-20 cards in a single PC.
8. The installation software for the Windows NT and Windows 2000 versions will issue
a prompt to add a DOS virtual-mode device driver file to the DOS CONFIG.NT file to
support DOS applications calling LON1. This will allow DOS applications to be used
in a Windows NT or 2000 DOS shell/window. For more information see Virtual-
Mode DOS Driver later in this chapter. The following line is added to the
CONFIG.NT file:
DEVICE=%SYSTEMROOT%\SYSTEM32\PCLTDOS.SYS /D1
The argument /D1 names this DOS device as LON1.
9. Software installation is complete. At the prompt to restart the computer, remove
the PCLTA-20 installation diskette, turn off power, install the PCLTA-20 card, and
then reboot the computer.
