Set Integration Time
Sets the Flame integration time in microseconds. The value is a 32-bit value whose acceptable
range is 1,000µs – 65,535,000µs. If the value is outside this range the value is unchanged. For
integration times less than 655,000us, the integration counter has a resolution of 10us. For
integration times greater than this the integration counter has a resolution of 1ms.

Set Shutdown Mode
Sets the Flame shutdown mode. When shutdown, the internal FX2 microcontroller is
continuously running however all other functionality is disabled. In this power down mode the
current consumption is reduced to 250mA (operating current for the FX2 microcontroller). When
shutdown is active (active low), the external 5V signal (V5_Switched pin 3) is disabled in
addition to all other signals except I

C lines.
Data Byte = 0  Shutdown everything but the FX2
Data Byte = !0  Power up entire Spectrometer
