2. INSTALLATION
2.1 SOFTWARE INSTAL LATION
Insert the PCI-COM CD into your CD drive. If your systems auto-run feature is enabled the PCI-COM
installation wizard will automatically launch.

Explorer and double clicking on it. Assuming your CD drive is the E: drive, SETUP.EXE will be in E:\
Follow the wizard’s instructions and accept the default settings if possible. An option is provided during
installation to copy an application that will restore the user settings after a reboot. This option should be
installed if the board will be operated in a mode other than the factory default configuration shown below.
2.2 FACTORY DEFAULT PORT CONFIGURATION:
Mode RS485
Transmit Control Auto Enabled
Max Baud Rate 115.2K
If the PCI-COM422/485 board will be operated at either a higher baud rate or in RS422 mode then the
configuration settings should be restored after reboot. This will prevent the end user from having to
manually reconfigure the hardware after each reboot (Figure 2-1).
Figure 2-1. Installation Option
Selecting yes to the above option during installation will cause the board settings to be stored in the
registry. When the computer is started the ComSet32.exe application will execute and restore the PCI-
COM422/485 hardware settings to their pre-shutdown state.
