Notes: * - User should not change these values because spectrometer performance can be affected. This
information is included just for completeness
& - These values are controlled by other command interfaces to the Flame (i.e., Set integration
time command).
Read Register Information
Reads the values from any of the registers above. This command is sent to End Point 1 Out and
the data is retrieved through End Point 1 In.

Read PCB Temperature
Reads the Printed Circuit Board temperature. The Flame contains a DS1721 temperature sensor
chip which is mounted to the underside of the PCB. This command is sent to End Point 1 Out
and the data is retrieved through End Point 1 In. The value returned is a signed 16-bit A/D
conversion value, which is equated to temperature by:
Temperature (
o
C) = .003906 * ADC Value
