10. The MP2x will now respond at the new address.
If you have multiple MP2x units, you can repeat these steps turning them on (or connecting them to the
MP2) one at a time and change the address. After completion, you can remove address 247 from the
system if it is not going to be used.

6 Input Register Map

The MP2x inputs are universal meaning they can support Thermistors (10K Type III), 0-6VDC or 0-20 mA
transducers, Dry Contact closures or Wet Contact closures. To eliminate program requirements on the
MP2x, we provided 10 different registers for each input. Select the appropriate register to poll based on
the type of sensor connected to the input. The complete register map can be found in Appendix A –
Modbus Register Table.

6.1 Thermistor Inputs

Connect a 10K type III thermistor to the desired input and then define the input in the MP2. Reference
the Modbus map for temperature sensors and select the desired reading. The example below shows
defining a Modbus point in the MP2 to look at input 10 on the MP2x and display the data in Celsius using
the floating-point register.
