Single Serial Port Module (optional)
To establish communication between the UPS and a computer, connect your computer to the
UPS communication port using the supplied communication cable.
When the communication cable is installed, power management software can exchange data
with the UPS. The software polls the UPS for detailed information on the status of the power
environment. If a power emergency occurs, the software initiates the saving of all data and an
orderly shutdown of the equipment.
Modbus/Jbus Module (optional)
The Modbus module provides monitoring and integration to the Building Management
Software (BMS) such as Wonderware. It features continuous and reliable communication
through isolated DB9 ports (RS48/RS232) or a terminal strip (RS48).
