4. Communications Interface
The communication port on the rear panel of the UPS allows for connection to a host computer.
When used with UPSMON communication software you will have access to important operating
information. From your computer screen, you can monitor input/output voltage, AC frequency,
battery voltage, etc., and analyze power problems. UPSMON will also initiate automatic graceful
shutdowns during extended power failures.
If UPSMON and a communication cable are not included in your UPS package purchase it
from your local dealer.
The following are some of the parameters you can monitor:
Input Voltage
Indicates the actual input voltage to the UPS when AC power is present
Output Voltage
Indicates the actual output voltage of the UPS
Input Frequency
Indicates the actual Input frequency of the UPS
Output Frequency
Indicates the actual output frequency of the UPS
Battery Voltage
Indicates the actual output DC voltage of the UPS battery
Load Percent
Indicates the percentage of UPS Voltage-Ampere(VA) capacity being
utilized by your equipment
The Imperial Series also supports software which relies on basic "contact closure signals" such as the
built in UPS Service in Windows NT (you will need to purchase a special cable for this type of
application). The major functions of this type of software normally include the following:
* To broadcast a warning when power fails.
* To close any open files before the battery rescues are exhausted.
* To turn off the UPS.
Note: You can connect your computer to your UPS without also connecting to the communication
port. In this case, your UPS warns you of a power failure by beeping, but you have to
manually shut down your UPS and computer.
