PowerChute does not discover Easy UPS On-Line (SRV/SRVL) during installation

Issue:
After connecting Easy UPS On-Line to Windows OS using the USB cable PowerChute Serial Shutdown (that has replaced PowerChute Business Edition) does not discover the UPS.

Product Line:
PowerChute Serial Shutdown v1.0 and above
PowerChute Business Edition version 10.0.5 and above

Environment:
All supported Windows OS
Easy UPS On-Line (SRV, SRVL)

Cause:
For the Easy UPS On-Line to be discovered and be able to communicate with PowerChute Serial Shutdown, USB to Serial driver must be installed prior to installing PowerChute.

Solution:
Download and install the driver attached to the FAQ. "Install_srv_driver"

Steps to Install the USB to Serial driver:
A Powershell script is provided to ease the process of installation.
Prerequisites
- PowerShell version 3.0 or later installed on your system.
- .NET Framework version 4.5.0 or later installed on your system.

If your system does not meet the above requirements, then the script will be unsuccessful. In this case you can try a manual installation of the drivers.

How to run the script

Change directory to the temporary folder where you unzipped the driver installation script.
