1 Revision History

The revision history describes the changes that were implemented in the document. The changes are
listed by revision, starting with the most current publication.

1.1 Revision 1.0

Revision 1.0 was published in May 2018. It was the first publication of this document.

2 Software Installation and Validation

The following section describes how to install and validate the software for the LX3301A/LX3302A
device.

1. Connect the dongle to the computer.

2. Connect the sensor PCB to the dongle.

3. Place your target at a desired air gap.

The first three steps are shown in the following image.

Figure 1 • System Setup

4. Set up your bench system to take measurements.

5. Launch Integrated Programming and Calibration Environment (IPCE), as shown.

Figure 2 • Launch IPCE

6. Verify that the port has opened, as shown.

Figure 3 • Verify Port Has Opened

Note: If it cannot recognize the dongle, then install the driver provided using device manager, then
unplug and replug the USB cable.

7. Read EEPROM from the chip (choose AOUT 11 for LX3301A or IO3 11 for LX3302A), as shown.

Figure 4 • Read EEPROM from Chip

If the result is the same as default parameters or previously programmed ones, then communication has
been done correctly.

If the result is as shown in the following three images, then communication has not been done correctly.

Note: Place the target with proper air gap distance if it won't read EEPROM correctly. Then, try to read
again. Adjust the target until it reads correctly.

The following image shows an example of a communication error. The sensor board is not connected or
AOUT/IO3 is stuck high. All data is FFFF.

The following image shows an example in which the IC detects fault or AOUT/IO3 is stuck at 0 V. The
sensor board is not connected or AOUT/IO3 is stuck high. All data is 0000.

Place the target in the proper position or fix AOUT/IO3 shorted GND.

Figure 6 • Example of IC Detects Fault or AOUT/IO3 Stuck at 0 V

The following image shows an example of IC unpowered (VIN). VIN is not connected. Data is garbled.

8. Use the default EEPROM data and write this default EEPROM data to the chip, as shown in the
following image.
