Note
This command requires that the string “aA” be sent without any CR or LF. This is
an attempt to ensure that this mode is not entered inadvertently. A legible
response to the version number query (v command) indicates the Flame is in the
ASCII data mode.
Binary Data Mode
Sets the mode in which data values are interpreted to be binary. Only 16 bit unsigned integer
values (0 – 65535) are allowed in this mode with the MSB followed by the LSB.
Command Syntax:
bB
Response:
ACK or NAK
Default value
Default at power up – not changed by Q command
Note
The command requires that the string “bB” be sent without any CR or LF. This is
an attempt to insure that this mode is not entered inadvertently.
Checksum Mode
Specifies whether the Flame will generate and transmit a 16-bit checksum of the spectral data.
This checksum can be used to test the validity of the spectral data, and its use is recommended
when reliable data scans are required. See Technical Note 2 for more information on checksum
calculation.
Command Syntax:
k{DATA WORD}
Value:
0 = Do not transmit checksum value
!0 = transmit checksum value at end of scan
Response:
ACK or NAK
Default value:
0
Version Number Query
Returns the version number of the code running on the microcontroller. A returned value of
1000 is interpreted as 1.00.0.
Command Syntax:
v
Response:
ACK followed by {DATA WORD}
Default value
N/A
