Note that the demo program will imply fields aside from the command (STX, LRC, and ETX)
D2 - Preamble
D3 - Postamble
To review the postamble using the demo, type 52d3 (not case-sensitive and spaces are optional (52 d3 is treated the same)) and click Send Command
The results will have
CMD: Command with STX, ETX, and LRC having been implied
OUT: 0602d3010003d3, where:
06 - ACK (an unsupported or wrong syntax command should give 0x15 or NACK)
02 - STX
d3 - Function ID for Postamble
01 - Length of setting
00 - Current setting (this means the device is outputting a null value for this field
03 - ETX
d3 - LRC by Exclusive OR
To set a single byte length field (these are most-typical), use a length of 0x01 followed by the setting (53140101)
To set an optionally and/or multi-byte field, give the length of the entire setting, plus length of the settings, such as:
[stx]53 D3 03 02 09 0D [etx] [lrc]- This will give a Tab followed by a Carriage Return
Other Common Settings
