Communication

A USB and an RS-232 port are available to enable the
communication between the UPS and a remote computer/
station. Only one communication port can be active at a time
and the priority is given to the USB port.
Once the communication cable is installed, the power
management software can exchange information with the
UPS. The software collects information from the UPS and
indicates the status of the device, the power quality of the
mains and the battery autonomy of the units.
In case of a power failure and a predicted shutdown of the
UPS due to low battery autonomies, the monitoring system
is capable of saving the data in the load and of initiating the
shutdown of the equipment connected to the UPS..

5.1 RS-232 port

The UPS has an RS-232 port for UPS monitoring, control
and firmware updates. To establish communication between
the UPS and a computer, connect one end of the serial
communication cable to the RS-232 port on the UPS and the
other end to the RS-232 port of a computer.
The cable pins for the RS-232 communication port are
described in Figure 39 and in Table 9.

5.2 USB port

The UPS can communicate with USB-compliant computers
that run power management software. To establish
communication between the UPS and a computer, connect
the USB cable to the USB port on the UPS. Connect the
other end of the cable to the USB port on a computer.
