SG_ <Mnemonic> : <Start>|<Length>@<BOM><Sign> (<factor>,<offset>) [<min>|<max>] "[unit]" [Receivers]

• Mnemonic: unique mnemonic name identifier for the Signal
• Start: Which bit (inclusive) does this signal begin at?
• Length: Total length of bits this signal encompasses
• Sign: + = unsigned; - = signed
• BOM: 1 = little-endian, Intel; 0 = big-endian, Motorola
• factor: decimal number multiplied with signal value (default 1)
• offset: decimal number added to signal value (default 0)
• [<min>|<max>]: relative to factor and offset. See below.
• [unit]: string representation of this value's units (e.g. mph)
• [Receivers]: space-separated BoardUnit (BU_) consumer list.

• Must begin with a single whitespace indentation
• Immediately follows the Parent Message (BO_), or another signal (SG_).
  • No padding with blank lines between them

 SG_ BattVoltage : 0|8@1+ (.1,0) [0|25.5] "volts" Vector__XXX

0.1 (factor) x 255 -> 25.5

 SG_ EngineRPM : 8|12@1+ (0.125,0) [0|512] "" Vector__XXX

0.125 (factor) x 4095->511.875 ~ 512

 SG_ FuelLevel : 8|16@1+ (0.00625,0) [0|41] "liters" Vector__XXX

0.00625 (factor) x 65535->41 liters, or 16.5 gallons

 SG_ <Mnemonic> [M|m<M-ID>] : <Start>|<Length>@<BOM><Sign> (<factor>,<offset>) [<min>|<max>] "[unit]" [Receivers]

• M: If M than this signals contains a multiplexer identifier.
• M-ID: Signal definition is only used if the value of the multiplexer signal equals to this value.
