Appendix D: Status Field Reference
D.1 Valid 16-Bit Positions
The positions used by the RMC are stored in a 16-bit number. This limits the range of positions to
65536 positions. However, by using the Scale and Offset parameters, the user can shift where
this 65,536-position range is located.
If Scale is positive, then Offset holds the lowest position value. Any positions displayed below this
value are not valid. They overflowed the absolute maximum supported position of 65,535.
If Scale is negative, then Offset holds the highest position value. Any positions displayed above
this value are not valid. They overflowed the absolute minimum supported position of -65,535.
Example 1:
Scale: 30,300
Offset: 0
Position Range: 0 to 65,535
Discussion: Because Scale is positive, the positions range from Offset to Offset + 65,535.
Example 2:
Scale: 25,604
Offset: -1000
Position Range: -1000 to 64,535
Discussion: Because Scale is positive, the positions range from Offset to Offset + 65,535.
Example 3:
Scale: 32,050
Offset: 1000
Position Range: 1000 to 65,535
Discussion: Because Scale is positive, the positions range from Offset to Offset + 65,535.
However, because the upper limit would be greater than 65,535 (66,535), it is truncated at 65,535.
Notice that positions less than the Offset (1000) are not valid. They were beyond 65,535 and
therefore wrapped back down to 0-999.
Example 4:
Scale: -30,300
