Command Descriptions
A detailed description of all Flame commands follows. The {} indicates a data value which is
interpreted as either ASCII or binary (default). The default value indicates the value of the
parameter upon power up.
Add Scans
Sets the number of discrete spectra to be summed together. Since the Flame has the ability to
return 32 bit values, overflow of the raw 16-bit ADC value is not a concern.
Command Syntax: A{
DATA WORD
}
Response: ACK or NAK
Range: 1-5000
Default value: 1
Pixel Boxcar Width
Sets the number of pixels to be averaged together. A value of
n
specifies the averaging of
n
pixels to the right and
n
pixels to the left. This routine uses 32-bit integers so that intermediate
overflow will not occur; however, the result is truncated to a 16-bit integer prior to transmission
of the data. This math is performed just prior to each pixel value being transmitted out. Values
greater than ~3 will exceed the idle time between values and slow down the overall transfer
process.
Command Syntax: B{
DATA WORD
}
Response: ACK or NAK
Range: 0-15
Default value: 0
Set Data Compression
Specifies whether the data transmitted from the Flame should be compressed to speed data
transfer rates. For more information on Flame Data Compression, see Technical Note 1.
Command Syntax: G{
DATA WORD
}
Response: ACK or NAK
Range:
0
– Compression off
!0
– Compression on
Default value: 0
Integration Time (16 Bit)
Sets the Flame’s integration time, in milliseconds, to the value specified. This command accepts
just a 16-bit value and is expressed in ms for backward compatibility with the USB2000. Use the
“i” command for full 32-bit functionality.
