Introduction

The MPACt 1500 controller has three types of
communications connections: an RS-485 serial port, an
ethernet port, and a USB port.
Use Ethernet or serial connections to connect the
transfer switch to a personal computer for system
monitoring and control using Kohlerr Monitor III
software or other Modbus applications.
The controller uses Modbusr TCP/IP communication
protocol over the Ethernet port. The controller uses
Modbusr RTU communication protocol over the serial
ports. The Modbus registers are available in the
Modbus Protocol manual.
Materials.
Note: Modbusr applications other than Monitor III
software require a Modbus software driver
written by a trained and qualified systems
programmer.
The USB port is used for file transfer between the
controller and a memory device. The USB port is a
standard 4-pin USB connector. The USB Access screen
appears when a device is connected to the USB port.
See Section 6.4 for instructions to transfer files through
the USB port.
