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.
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
Set FPGA Register Value
Sets the appropriate register within the FPGA. The list of register setting is in the USB command
set information. This command requires two data values, one to specify the register and the
next to specify the value.
Command Syntax: W{
DATA WORD 1
}{
DATA WORD 2
}
Value:
Data Word 1
– FPGA Register address
Data Word 2
– FPGA Register Value
Response: ACK or NAK
Default value: N/A
ASCII Data Mode
Sets the mode in which data values are interpreted to be ASCII. Only unsigned integer values
(0 – 65535) are allowed in this mode and the data values are terminated with a carriage return
(ASCII 13) or linefeed (ASCII 10). In this mode the Flame “echoes” the command and data
values back out the RS-232 port.
Command Syntax: aA
Response: ACK or NAK
Default value N/A
