Wireless M-Bus - Manufacturer ID calculation
The generic ID can be derived from the manufacturers ID list maintained by DLMS User Association. This list can be found here: https://www.dlms.com/flag-id/flag-id-list
Calculation of the 16-bit manufacturer ID used in EN 13757-4 based on those three letter codes is like this:
32 x 32 x <A> + 32 x <B> + <C>
Whereas, <A>, <B> and <C> correspond to the number of the character within the alphabet.
The three letter code for manufacturer STACKFORCE is STF.
The character number within the alphabet for the single letters are: S=19, T=20 and F=6.
This leads to:
32 x 32 x 19 + 32 x 20 + 6 = 20102 = 0x4E86
