PowerChute Business Edition not discovering Smart-UPS when using 940-0272A cable

Published date: 09 April 2020

Issue,
After connecting Smart-UPS to Windows OS using the 940-0272A cable PowerChute Business Edition does not discover the UPS.

Product Line:
PowerChute Business Edition

Environment:
All supported Windows OS
Smart-UPS

Cause:
To use the 940-0272A cable with PowerChute Business Edition the Prolific USB to Serial driver must be installed prior to installing PowerChute. 

Solution:
Download the latest Prolific PL2303 driver from http://www.prolific.com.tw/US/ShowProduct.aspx?p_id=225&pcid=41

For Windows Server Core/Hyper-V the Prolific USB/Serial driver must be downloaded from Windows Update Catalog onto the Windows Server Core/Hyper-V Server. The cab file must be extracted to local drive and pnputil -i -a ser2pl.inf must be run to install the driver. Windows systems with GUI need to have the Add New Device wizard check Window Update for the driver. Once the driver is installed, reboot the server so the COM port is registered in the OS.
