Offset Variables~

Offset	Variable name	Max	Resolution	Unit	Comment
0-26	ASCII coded numbers	255	1	ASCII	Sequence of numbers. Examples: HMC310 25303763146288737718903, RC100.2 H 05704801002367738112973, MX300 25303394051798738806124
27-42	Product name ASCII coded	255	1	ASCII	Should be \0 terminated, but is not always. i.e. Heat Pump responds with 43 55 48 50 = "CUHP", but \0 is missing
43-69	More data	255	1	-	Some devices send more data after offset 43. Either a series of 00 or FF
