This program is used to perform configuration of a Technologic Systems Modbus device. On older Modbuc devices these settings (Slave address, Communications bit rate and data format, termination) would have been performed via DIP switches. This configuration information is stored in non-volatile memory on the device. This utility is designed to operate on devices confired as factory degault, 9600, N81, address 0cf7. Windows USB connections are not currently supported, so the devie should be connected via a TS-142 ISB to Serial Modbus adapter is required.
