Driver Installation/Upgrade Procedure
Download the lastest Perle-Serial driver zip file from the Perle website for your 
operating system:   - for 32-bit Windows operating systems.   - for 64-bit Windows operating systems.  - for 64-bit Windows Itanium operating systems. 

Unzip the driver zip file to a local directory. 

Install the required Perle-Serial cards into the PC. When the PC boots, the OS 
will attempt to install drivers for the new hardware. Hit cancel when each of 
cards are found.

We recommend that you use the pserial-setup-<arch>.exe installation program, 
which will launch the installation wizard and create an installation 
sub-directory in the "Program Files" directory and then run the UpdateV2 
program which will install the driver for each card that was detected on bootup.

When adding new cards to a system with the driver already loaded, run the 
Update Driver program from the Start menu. Located at
"Start/All Programs/Perle/Perle-Serial/Update Driver".

To upgrade drivers for installed devices, install the new driver package.
This will update the files in the installation directory and then update all 
installed Perle-Serial type devices with the drivers found in this package. 


Known issues in this release :
* None

Driver Updates :
These drivers will be updated from time-to-time. Please visit the Perle
Web-Site at to ensure you have the latest release.
