7 Interfaces and communication

7.1Computer 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.

7.2Communication 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.
