6. Computer and Alarm connections
At the back of the UPS is an interface allowing direct communication with your computer
system, the location of which can be found in figure 2. There is a RS232 serial data interface,
one USB data interface and an emergency power off switch supplied. However, the RS232
port cannot be used when the USB interface is in use.
In addition there is an optional interface slot that allows you to install different
communications cards. It can be used parallel with either the RS232 or USB ports.
Currently there are two cards available for the optional interface slot. An SNMP/WEB card
allows management and monitoring over a network or internet, and the AS/400 card allows
voltage free relay contacts. Your local dealer will have more information about these option
cards.
Connecting the UPS to a Computer
The communication device for the UPS and PC comes as a complete package with power
management software. Only the communication cable provided with UPS may be used to
connect to your computer, which is accomplished through the UPS RS232 port. Also ensure
that the operating system on your computer is supported. Instructions provided in the power
management software will help with this installation.
Other advanced power protection solutions such as SNMP are provided by your dealer.
RS-232 Standard Interface port
The RS-232 interface uses a 9-pin female D-sub connector. This information consists of data
about utility, load and the UPS. The interface port pins and their functions are identified in
the following table.
Pin # Signal name Direction (re UPS) Functions
2 TxD Output TxD Output
3 RxD Input RxD / Inverter Off Input
5 Common Common
6 CTS Output Ac Fail Output
8 DCD Output Low Battery Output
9 RI Output +8-24 VDC Power
Caution! Max rated values 24Vdc/50mA
