Command Syntax:
S
Response:
If successful, STX followed by data
If unsuccessful, ETX
The format of returned spectra includes a header to indicate scan number, channel number,
pixel mode, etc. The format is as follows:
WORD 0xFFFF – start of spectrum
WORD Data size flag (0Data is WORD’s, 1Data is DWORD’s)
WORD Number of Scans Accumulated
WORD Integration time in milliseconds
WORD FPGA Established Baseline value (MSW)
WORD FPGA Established Baseline value (LSW)
WORD pixel mode
WORDs if pixel mode not 0, indicates parameters passed to the Pixel Mode command (P)
(D)WORDs spectral data depending on Data size flag
WORD 0xFFFD – end of spectrum
Trigger Mode
Sets the Flame’s external trigger mode to the value specified.
Command Syntax:
T{DATA WORD}
Value:
0 = Normal (Free running) Mode
1 = Software Trigger Mode
2 = External Hardware Level Trigger Mode
3 = External Synchronization Trigger Mode
4 = External Hardware Edge Trigger Mode
Response:
ACK or NAK
Default value:
0
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
