PowerChute Business Edition not recording lost comms in a serial-to-USB configuration

Issue:
PowerChute Business Edition not recording lost comms in a serial-to-USB configuration

Product:
PowerChute Business Edition

Environment:
All supported Windows OS

Cause:
When you have the following configuration:
* the 940-0272A cable ,
* connecting a serial port on the Smart-UPS SC 1500 to a USB port on a server ,
* and running with the PL2303 driver from the Prolific company,
and the cable is disconnected, accidentally or otherwise, then PCBE is unable to report it as a lost communications event.
(This happens because when the cable is disconnected, the Prolific driver is disabled).

Solution:

If this happens you must reconnect the USB plug to the CORRECT USB port on your server and restart the APC UPS Windows service: "APC PBE Agent".

We strongly recommend, if possible , that you use a serial-to-serial connection to avoid this situation from arising.

NOTE: If issue is connecting Smart-UPS SC to Windows OS using the 940-0272A cable PowerChute Business Edition does not discover the UPS please see Kbase FA283834
