NOTES: 1- Full range is defined as "from negative full input angle to positive full input angle"

2 - Non-linearity is specified as deviation of output referenced to a best fit straight line, independent of misalignment.

3 - In default condition without averaging.

4- Default Baud Rate is 38400

5 - Not factory set - Operator depended EIA-485 or EIA-422
