5. Computer and Alarm Connections

At the rear of the UPS is an interface that allows direct communication with a computer

system (see figure 2). There is a RS232 serial data interface, a USB data interface, and

an emergency power off switch. The RS232 port and the USB interface cannot be used

simultaneously.

In addition there is an optional interface slot that allows for the installation of

communications cards. It may be used in parallel with either the RS232 or USB ports.

An SNMP/WEB card is available for the optional interface slot that allows for the

RemotEye II to manage and monitor the system over a network or over the internet.

RS-232 Standard Interface Port

Only the communication cable provided with the UPS may be used to connect the UPS

to a computer when using the RS232 port of the UPS. Ensure that the operating system

of the computer supports RS232 communications. Other advanced power protection

solutions, such as SNMP, are available from your dealer.

The RS-232 interface uses a 9-pin D-sub connector. The names and functions of the port

pins are listed in the following table.
