7 Interfaces and communication
7.1 Computer interfaces RS232
The UPS offers various interfaces to manage the system and
to comfortable readout state information and important
parameters. The communication protocol is optimized for
operation with the shutdown and UPS management software
“CompuWatch” from AEG. To connect the UPS to your
computer use the provided RS232 communication cable by
attaching them to a free port of your pc.
RS232 interface: The interface is connected via a 9 pole
Sub-D connector on the back of the unit (pos. 4 p. 26). PINs:
2 = RxD; 3 = TxD; 5 = GND.
7.2 Communication Slot
If the cover on the rear of the UPS is removed (pos. 8 p. 26),
additional optionally available communication components
can be installed there.
AS/400 board: Slot card with status messages, realised via
potential-free relay contacts
USB board: Slot card for external USB connection
SNMP board: Slot card for direct connection of the UPS to
the Ethernet network with RJ 45 (TCP/IP)
Details can be found in the description enclosed with the
particular optional component. Other boards are in
preparation.

The usage of the communication slot deactivates
the RS232 interface from chapter 7.1.
7.3 Shutdown and UPS management software
The "CompuWatch" software specially developed for these
purposes by AEG continuously checks the mains supply and
the UPS status.
