XUSB In
General Information
While connecting a UPS to a USB interface at a PC, the information on the exis-
tence and the state of the UPS are communicated to the PC via a USB connec-
tion. The communication is established via a virtual COM interface provided by
the USB interface.
The electrical properties of the XUSB In interface correspond to the properties
of the standard USB interface.
The driver is part of the operating system of the panel PC or control
cabinet PC; therefore no additional driver installation is required.
