Set Fields Command

Set Fields ('SF' = 0x5346)
Preamble Packet Type
0x5555 0x5346
This command allows the user to set the unit's current configuration (SF) fields immediately
which will then be lost on power down. NumFields is the number of words to be set. The field0,
field1, etc. are the field IDs that will be written with the field0Data, field1Data, etc., respectively.
This command can be used to set configuration fields. The unit will not set calibration or
algorithm fields. If at least one field is successfully set, the unit will respond with a set fields
response containing the field IDs of the successfully set fields. If any field is unable to be set, the
unit will respond with an error response. Note that both a set fields and an error response may be
received as a result of one set fields command. Attempts to set a field with an invalid value is one
way to generate an error response. A table of field IDs and valid field values is available in
Section 7.1.
