Cabinet PC to XCOM1
General Information
While connecting a UPS to a RS232 interface at a PC, the information on the ex-
istence and the state of the UPS are communicated to the PC via a serial inter-
face.
The electrical features of the XCOM1 interface correspond to the features of a
standard RS232 interface.
The driver is part of the operating system of the panel PC or control
cabinet PC; therefore no additional driver installation is required.
