7 Interfaces and Communication
7.1 Computer Interface RS232
For the control of the UPS and convenient reading of status
messages and measured values, various interfaces are
available. The interface protocol is designed for operation with
the "CompuWatch" shutdown and UPS management software
from AEG. Use the supplied RS232 communication cable to
connect your PC. Plug the cable into a corresponding serial port
on your PC.
RS232 interface: The RS232 is connected via the 9-pin Sub-D
socket strip on the back of the unit (no. 8, p. 27/28). Pin
assignment: 2 = TxD; 3 = RxD; 5 = GND.
7.2 Communication Slot
On the back of the UPS, there is a cover (see p. 27/2828, no.
7). When this is removed, additional, optionally available
communication components can be installed there, e.g.:
AS/400 board: Slot board with status messages, realised via
potential-free relay contacts
USB board: Slot board for communication via USB
SNMP board: Slot board 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 in preparation.

Using 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.
In conjunction with the “intelligent” UPS, this guarantees the
availability of the EDP components as well as the data security.
