Mc-8 Set Parameter Value By Id - Lexicon MC-8 V1.0 - SERIAL COMMUNICATIONS PROTOCOL DEFINITION REV 1-4 Manual

MC-8 Serial Communications Protocol
values are packed LSB first(CurrentValue [0]) to MSB(CurrentValue [0+(num bytes-1)]). For
example: Setting a given signed 16 bit parameter to a value of -300 the data array would be
packed as follows:
Data[0] = 0xd4
Data[1] = 0xfe
Data[2 - 13] = don't care.
If a parameter's current value is a signed 16 bit parameter with a value of -3 the data array would
be packed as follows:
Data[0] = 0xfd
Data[1] = 0xff
Data[2 - 13] = don't care.
All signed values are in the 2's compliment format.
Max Value:
This is a 16 bit value representing the maximum value for a parameter. Parameter values
exceeding the maximum will be limited to the maximum. This may be a signed or unsigned value
depending on the Parameter Type.
Min Value:
This is a 16 bit value representing the minimum value for a parameter. Parameter values
exceeding the minimum will be limited to the minimum. . This may be a signed or unsigned value
depending on the Parameter Type.
Parameter Path:
This is a zero terminated ASCII character string describing the parameter's name and path in the
units parameter tree structure.
Read Only:
Data Type:
TRUE:
FALSE:

6.3.24 MC-8 Set Parameter Value by Id

MC-8 Set Parameter by Id command sets the parameter value equal to the value sent in the command packet and
then runs the appropriate functional changes associated with changing the given parameter.
