FM2 uses FM4 data protocol as well as configuration protocol. Remote firmware
update protocol is same for FM2 and FM4 (see FM4 Protocols document for more details),
remote configuration protocol is also same, but note, that FM2 uses only one profile and all
parameters must be changed only in profile1.
Full list of FM2 parameters is listed below.
