6.2 UPS communication connection
To exchange data with the UPS, there is a convenient communication inter-
face.
Only one communication port can be active at any one time. The USB port
takes priority over the RS232 port.
The software can exchange data with the UPS if a communication cable is
connected. The software gathers detailed information about the status of the
energy supply from the UPS. In the event of a supply emergency, the software
ensures that all data is saved and that the devices are powered down correctly.
