PAL composite video out from the TAU core The video standard and other video related settings can be configured with FLIR TAU GUI see chapter 2 1 1 3 USB Interface for Memory Stick This is a USB host interface which is intended to be used with a small USB memory stick It is able to power common memory sticks but not USB hard drives ThermalCapture stores the captured images on the memory connected to this interface 1 1 4 Trigger and Serial Connector The trigger and serial connector has the following pin definition Trigger IN GND Serial IN NC Reserved RW DN gt Image capture is triggered when the Trigger IN pin is pulled to ground It is connected to 3 3V internally via resistor You can apply a switch or a transistor between 1 Trigger IN and 2 GND It 4 16 ThermalCapture User manual is also possible to connect a digital signal 0 5V to the trigger input Images are captured as long as Trigger IN is at ground level It is not possible to connect the trigger input permanently to GND because in this case there would be no way to switch ThermalCapture off or release the memory stick without potentially damaging its file system Serial IN is a UART interface It supports inverted and not inverted signals 0 5V The data received at this pin is continuously stored in an internal buffer This buffer is added to any stored image So it is possible to connect a GPS receiver or an I

5. the complete process from power up through data recording to power down is described 3 1 Power On You can power on with or without a connected memory stick ThermalCapture begins to boot immediately when 5V is supplied to the MINI USB connector During boot up the LED on the back side glows red This will take one or two seconds After boot up ThermalCapture waits for the USB Memory stick and the LED glows green When the stick was found and ThermalCapture is ready to work this LED will start blinking green 3 2 Data Recording When the trigger input is pulled to ground images from the TAU core are captured and stored to the USB stick The LED on the back side will flicker red and the letters REC are shown in the analog video output Do not power off ThermalCapture or release the USB stick when the red LED is flickering The file system of the USB stick may get damaged If an error occurred while writing the data to the USB stick the LED will blink green and red alternately This will even happen if the USB stick is full 3 3 Power Off Every time the LED does not flicker red it is safe to remove the USB stick or to power off ThermalCapture Power off can only be done by turning off the power supply which is connected to the MINI USB connector 11 16 ThermalCapture User manual 4 Post Processing with ThermoViewer Software ThermoViewer is the post processing software provided by TeAx Technology to process RAW data cap

MU to ThermalCapture Since the data is only stored but not processed at ThermalCapture any UART based protocol can be used as long the sensor begins with data output on its own Interface settings baud rate etc can be done with the serial configuration tool see chapter 2 5 16 ThermalCapture User manual 2 Configuration Before ThermalCapture can be used in a specific setup it is necessary to configure the TAU core correctly Configuration of ThermalCapture is only needed if the serial input see chapter 1 1 4 is used to connect to a GPS receiver or a similar device 2 1 Configuration of the TAU Core TAU core configuration is only necessary if you have mounted ThermalCapture to a TAU core on your own or if you want to change some core related settings If this is not the case please proceed with chapter 2 2 2 1 1 Driver Install ThermalCapture uses the FTDI232RL USB serial converter IC to connect the TAU core to the Mini USB interface To get access to the TAU core with your PC you may need to download and install the FTDI VCP driver from http www ftdichip com Drivers VCP htm After installation the TAU core is connected to a virtual serial interface COMX Please open the device manager and look which COM interface it has got i a Datei Aktion Ansicht e EH sz 4 iO marku s winZvrm gt 4g Akkus a Anschl sse COM amp LPT LIE j Druckeranschluss LPT1
