Software Setup For Standard Software
Applications
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 4.3.1-4. 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 (see sections 12.2 and 12.3).

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.

USB port
Connecting the UPS to your computer is accomplished through the USB port on the
back of your computer.
USB compliant hardware and operating system will be necessary including
installation of a USB driver.
The serial port cannot be used when using the USB port.
The USB cable is standard and must be bought separately.
