UPS MONITORING CONFIGURATIONS

All models except A300 provide a UPS monitoring capability which will allow direct interface with many different computer operating systems. This capability permits an unattended, orderly shutdown of the computer system when commercial power is lost for a long period. Some configurations also provide for a shut down of the UPS after the computer has been shut down, thereby conserving UPS battery capability.

Para Systems also offers its own software package, which functions with Novell, Unix-based, OS/2, Windows and Macintosh operating systems. This package offers many advantages over existing UPS monitoring packages.

Finally, for systems which do not have UPS interface capabilities, user software can be written to read UPS status and provide for system shut down. Software specialists should contact Para Systems, Inc. for more information. The standard UPS DB9 PIN out is provided below for your information.

COMMUNICATIONS PORT

The communications port on the back of the UPS (DB9 Female Connector labeled "Signal") can be connected by a cable to a computer to provide the UPS monitoring capability described above. Following are the pin connections of this connector.

 

UPS DB9 PIN OUT

PIN 1

N.C.

PIN 2

UPS simulates a relay closing (open collector transistor) between Pins 2 and 4

 

when it switches to Inverter mode.

PIN 3

Not used

PIN 4

Common ground return (for Pins 2, 5, 6 and 8).

PIN 5

UPS simulates a relay closing (open collector transistor) between Pins 5 and 4

 

at low battery warning.

PIN 6

User sends a RS232 high level (9-12VDC) to turn off the UPS (works only

 

during Inverter operation). UPS returns to AC mode when commercial power is

 

restored.

PIN 7

Common with Pin 4.

PIN 8

A500 and larger units: When this pin is shorted to ground, UPS output turns off.

 

Output returns when commercial power is available and the short is removed.

 

On units smaller than the A500, this pin has no connection.

PIN 9

Reserved.
