V. DESCRIPTION OF DATA :
For the following Bit Pattern. The LSB is always bit 0. Bit numbers are always counted from
right to left, with the rightmost digit being bit 0, and the next to the left would be bit 1.
1. INPUT RANGE:
This is one byte data (2 characters). This byte will specify input range and other input
configurations of each model. Bit pattern for different models :
