All data is sent in the units shown and is independent of the units selected.
Data is sent 9600 baud 8n1. Sensors that are not functioning or are out of range will return 'EE' as the measurement. The last byte in each group is a checksum of that group. It is calculated by performing an unsigned add of all the bytes in the group, including the group number but not the checksum byte. The checksum is the lo-order byte of the sum.
