PAX2A MODBUS REGISTER TABLE
The below limits are shown as Integers or HEX < > values. Read and write functions can be performed in either Integers or Hex as long as the conversion was done
correctly. Negative numbers are represented by two’s complement.
Note 1: The PAX2A should not be powered down while parameters are being changed. Doing so may corrupt the non-volatile memory resulting in checksum errors.
