Description
M1
M1 is the legacy data format used in the WMA-4 (previous model to the WMA-5).
Note: this format is NOT comma delimited.
An example is:
M1100012801131900968115025000000000000000000000099700<CR>
The format is as follows:
M1: Determines what data format is being displayed. In this case, M1 is WMA-4
format. (position 0,1)
WMA ID: 0-9. (Identifier for WMA-5 when multiple units are used). (position 2)
Record #: 1-9999. (position 3-6)
Day: 1-31. (position 7,8)
Month: 1-12 (January - December). (position 9,10)
Hour: 1-24 (based on 24 hour clock). (position 11,12)
Minutes: 0-59. (position 13,14)
