Remote monitoring
The UPS unit is fitted as standard with an RS 232 signal output. This signal output is designed as a RS232-
interface (SUB-D, 9-pin), and there is optionally the possibility of using an additional USB interface.
Concerning these two interfaces there is the limitation that only one or the other, that is the RS232 or the
USB interface, can be used at one time. There is also the option of using the additional rack at the rear. This
rack can be fitted with two different cards, one with an SNMP adapter, which allows monitoring of the UPS
via the network or the internet, or an AS/400 card with voltage-free contacts.
The RS 232 and USB interfaces serve to allow data transmission between a computer and the UPS unit.
The UPS unit can be monitored and checked by a computer through the use of special software. Switching
off of the UPS unit in the case of power failure is possible.
9.1
Connecting the UPS to the computer
The communication between the UPS and computer is delivered as a complete package including the
communication cable and management software. It is absolutely essential to use the communication cable
delivered since it was directly configured for the RS 232 interface. Ensure that your operating system is
compatible with the management software. Instructions for the management software will aid you in installing
the software properly.
9.2
Assignment of the RS232 interface
The RS 232 interface uses a 9-pin SUB-D connector (jack). Assignment of the SUB-D connector is as
described in the table below.
