8 Interfaces and Communication

8.1RS232 and USB computer interfaces

There are several different interfaces available to control the UPS and conveniently read out status messages and measurements. The interface log is designed to be used with “CompuWatch”, the shutdown and UPS management software from AEG. Use the RS232 or USB communication cable that comes with the device to connect your UPS to a PC.

The USB and the RS232 communication interface

rule each another out, i.e. either USB or RS232.

Pin allocation of the RS232 Sub-D9 jack:

2 = TxD; 3 = RxD; 5 = GND

SNMP card: Plug-in card for the direct integration of the UPS

 

 

into the Ethernet network via RJ45 (TCP/IP)

 

SNMP PRO card: As above, but with the additional option of

 

connecting and managing an external sensor system

 

For details, please refer to the descriptions that come with each

 

option. Additional cards are in preparation.

The communication slot can be used in parallel to

 

the RS232 or USB interface.
