Introduction
The EVB90614 is designed to support MLX90614 infrared thermometer modules. The communication between PC and the evaluation board is accomplished by USB. The Demonstration Kit contains the following items:
1. FS USB demonstration board, pre-programmed with USB
bootloader and demonstration firmware.
2. A standard USB cable for use in communicating with the board.
3. 2 pcs. MLX90614AAA (single zone 5V)
4. 2 pcs. MLX90614BAA (single zone 3V)
5. CD-ROM, containing the USB HID driver and EVB90614 software
The EVB90614 is designed to allow OEMs to configure the MLX 90614 IR thermometer for virtually any application quickly. OEMs can quickly experiment with temperature ranges, optics, etc. to find the best IR configuration to meet the application needs. Once the best configuration is established, low volume OEMs can easily configure IR modules for their own use. For high volume OEMs, Melexis can supply special configured modules, ready to install into the customer’s application. Please contact IR Sales at Melexis for quotations.
The EVB90614 allows engineers to customize the MLX90614 for high accuracy IR measurements in an R&D or Laboratory setting.

Host computer requirements
To communicate with and program the EVB90614 evaluation board, the following hardware and software requirements must be met:
• PC-compatible system
• An available USB port
• CD-ROM drive (for use with the accompanying CD)
• Microsoft Windows 98, Second Edition (98SE), Windows 2000 Desktop or Windows XP
Note1: EVB90614 is HID USB device and will require no drivers on PCs that support HID class USB devices (except Microsoft Windows 98, Second Edition (98SE)). Check www.melexis.com for most recent release of the software.
3
Installing the software
As an USB device, the demonstration board requires very little effort to install. Most of the work is done by the operating system. The software is installed simply by running the file “setup.exe”. The software will be installed in a separate Melexis directory and can be accessed from Start/Programs/Melexis/ Mlx90614 Configurator.
Note2: If your version of Windows does not support the HID USB devices you might need to install USB driver (check
www.melexis.com
for such driver).

Fig.4.1
Top view of evaluation board is shown on Fig.4.1.The main elements include:
1. Extension connector (70553-0003 from www.molex.com) allowing additional
MLX90614 modules to be connected to SMBus.
Connector pin description: pin1 - SCL/Vz (pin 1 is marked on the plastic body of the connector) pin2 - PWM/SDA
pin3 - Vdd
pin4 - Vss
2. ZIF socket for MLX90614
3. Button “next”
4. Button “start”
5. Button “reset”
6. RGB status LED
7. USB "B" Receptacles
The EVB90614 board receives its power supply only from the USB cable (Bus-Powered Device). External power supply source is not needed.

4.2 Connecting the EVB90614 evaluation board
To connect the evaluation board:
1. Unbox and unwrap the board, and set it on a non-conductive surface near the
host system.
2. Connect the USB cable (supplied in the kit) to an open USB port on the host system or a USB hub connected to the host system, and to the USB connector on the board. The LED will shine in BLUE.
3. EVB90614 evaluation board is HID compliant device so a special USB device driver is not needed (except when using Window 98 & 98SE).
4. Check the board connection. This can be done from Start/Settings/Control Panel/ System/Hardware/Device Manager (Fig.4.2).

Getting started with MLX90614 Configurator
5.1 MLX90614 Configurator overview
The MLX90614 Configurator is a Windows-based software application designed to be used with the EVB90614 evaluation board for evaluating Melexis MLX90614 infrared thermometers. Using this software, features and performance of MLX90614 infrared thermometers can be evaluated. All basic configurations of MLX90614 are also supported in user-friendly format. Configuration is written in EEPROM of each MLX90614 and will be the POR default afterwards. This way the MLX90614 can be further used without EVB in target applications.
5.2 Working with MLX90614 Configurator
Insert a MLX90614 thermometer in the ZIF socket (see Fig.4.1). Make sure that module benchmark coincides with the mark on the PCB. The software can be launched from Start/Programs/Melexis/ MLX90614 Configurator.

The Configurator automatically recognizes the module type, address and voltage supply (Fig.5.1). The status LED is shinning GREEN.
Fig.5.1
If there is no thermometer module inserted on the EVB or the module is not a MLX90614, the user will be notified (Fig.5.2). Click the button OK. The main panel looks as shown in Fig.5.3.

Fig.5.3
Note that the buttons Power off and Refresh are alternating. The MLX90614 Configurator gives the opportunity to connect a few MLX90614 modules in a network (Fig.5.4). Note that if in a network both 3V (MLX90614Bxx) and 5V (MLX90614Axx) modules are present, currently only the 3V modules will be available.
