2.6.3 RESETTING CONFIGUR ATION ON POWER UP
The PCI-COM board will power up with the mode set to RS485 and UART Clock Rate set to 1.8432 MHz. If you
change the UART Clock Rate or mode via the Device Manager Property Page, you must execute the ComSet32.exe
application to restore the settings after a reboot. The Device Manager configuration dialog writes the chosen settings
to the registry. The ComSet32.exe application reads the settings from the registry and restores the PCI-COM
hardware configuration.
During installation, the user has the option to install a shortcut to the ComSet32.exe in the Startup folder. If you
select this option, (see Figure 2-1) your PCI-COM422/485 hardware configuration is maintained across reboots. If
you select NO, at each reboot the PCI-COM422/485 board is restored to its default configuration.
Note: The default settings for the hardware are RS485 mode with rates up to 115.2 kbaud.
If you selected NO during installation, when prompted about installing the ComSet32.exe, then you can manually
create a shortcut and copy it to your Startup menu. The ComSet32.exe application is installed in the directory
specified during installation. The default installation directory is C:\cb. To create a shortcut do the following:
1. Start the “Windows Explorer” application and open the installation directory.
2. Right click on the “ComSet32.exe” entry.
3. Select the “Create Shortcut” option from the drop down menu.
4. Under Windows 95/98: Copy the shortcut to the Startup folder
(C:\Windows\Start Menu\Programs\Startup).
