MLX90601 Configuration Board
Introduction
The MLX90601 Configuration board is designed to support the MLX90313 based Infrared Thermometer
modules. For example the MLX90601C Infrared Thermometer Module can be configured using the
configuration board and software.
The hardware board acts as an interface between the RS-232 computer link and the module's SPI
interface. Also it supplies the supply voltages to the module.
The accompanying software will greatly simplify the configuration of the module. It allows the user to
change output options, use other temperature ranges, save and retrieve configuration settings to disk, set-
up the comparators and more. For all inside information of the MLX90313 programmable IR sensor
interface, please refer to the MLX90313 datasheet.

Page 6: How To Use The Software
User Manual MLX90601 Configuration Board How to use the software Overview The MLX90313 datasheet describes completely how to change the operation of the modules. However, most users will find it much more convenient to use the configuration board. The software package, in combination with the configuration board, allows you to change all internal settings without effort. - Page 7 User Manual MLX90601 Configuration Board Displaying measured temperature on the screen Let’s start simple.

- Page 11 Temperature range rescaling basics Applications may require temperature ranges that are different from the factory calibrated ranges. The demonstration and configuration software supplied with the MLX90601 configuration board contains a utility to rescale the temperature ranges of the modules. Both the ambient temperature measurement and object temperature measurement can be rescaled inwards, i.e.

- Page 14 User Manual MLX90601 Configuration Board Changing the current calibrated temperature ranges. The 90313 based modules have a certain calibrated range for both object and ambient temperature. The minimum output value corresponds with the lower calibrated temperature limit, and the maximum output value corresponds with the upper calibrated temperature limit. These minimal and maximal temperature limits are not stored in the eeprom, and can thus not be automatically set-up by the software package.
