The LMxxEVAL kit includes the SensorEval software, which is provided by National Semiconductor to
communicate with the LMxx Evaluation Board by way of the USB cable (not provided) from the
controlling computer. The SensorEval software is used to control the writing and reading of the digital
registers in the LMxx for doing the initial register setup, reading the local and remote temperatures,
establishing certain temperature limit setpoints.
For the installation procedure for the SensorEval software see the readme.txt file on the SensorEval
software CD. For detailed use of the LMxx software used with the LMxx Evaluation Board, please
refer to the SensorEval software user’s guide on the CD. The LMxx datasheet is available at
www.national.com.

2.2 Optional Equipment
Optional pieces of equipment are as follows:
2.3 Test Setup - Software
First, see the readme.txt file on the SensorEval CD for the latest installation instructions. Follow the
installation procedures to load the software on the computer and, if desired, to verify the operation of
the LMxx Evaluation Board.
The SensorEval icon will be on the desktop window after the software installation.
For use with the LMxx Evaluation Board disconnect the USB cable from the board and proceed to the
next section for the hardware setup.
If it is desired to run the software, without the LMxx Evaluation Board, please proceed to the next
section for the hardware setup.
