Modifying Modbus Registers
The setup parameters of the H
2
sensor can also be modified by adjusting the Modbus registers.
A list of all Modbus registers can be found in “Appendix 1: Modbus Register Map”. To make
modifications, you must connect the sensor to a computer that uses SSI’s “Configurator”
software. When communicating with Configurator, use a straight-through serial extension
cable connecting the computer to the sensor. Set the baud rate in Configurator to 9600. On the
sensor, set DIP Switch #4 to Off for Modbus communication, and be sure that the jumpers are
on pins 2 and 3.
