1 Introduction The purpose of this document is to give guidelines for use and integration of the TeraRanger Evo 60m and TeraRanger Evo 600Hz distance sensors with (a) UART/I2C backboard, and/or (b) USB backboard using these standard communication interfaces. 2 Mechanical integration The mechanical design of the main sensor module (black) allows easy assembly to its backboard (yellow) using a simple ‘clip-in’ technique.
2.1 Mechanical design 2.2 Sensor handling during system assembly During assembly and integration, please observe all common ESD precautions. All optical surfaces (sensor front) should be kept clean and free from contact with chemicals. 3 USB backboard use The USB backboard comes with a standard Micro-USB connector. 3.1 Graphical User Interface (version 1.0.2) A free Graphical User Interface (GUI) is available, providing an easy way to visualize the data from your TeraRanger Evo.
checking some of the basic parameters of the sensor. It also provides a way to easily upgrade the firmware running on the device. The GUI is available for download here: GUI Download. (See “Download” section of the TeraRanger Evo product page). Please ensure you are using GUI version 1.0.2 or later. If you need to identify which TeraRanger Evo sensor is currently connected, in the GUI select, Help > About. 3.1.
3.1.3 Firmware Upgrade The current firmware version on your TeraRanger Evo can be found by selecting Help > About in the graphical user interface. It is possible to upgrade the firmware running on your device if a new firmware version is made available on the Terabee website. Please note the Upgrade Firmware feature is only supported on Windows 7, 8 and 10. Please carefully follow the steps outlined below to avoid permanently disabling your device.
3.2 Connecting the TeraRanger Evo to a Host Computer TeraRanger Evo can interact as a virtual COM port using the following configuration: 115200 bit/s, 8 data bits, no parity bit and one stop bit. In Windows you can also use any terminal emulation software of your choosing, however we suggest you use HTerm (http://www.der-hammer.info/terminal/). Extract the downloaded zip file to the folder of your choice, open it and double click on the “HTerm.exe” document.
4 I2C/UART backboard use 4.2 I2C/UART interface The TeraRanger Evo can be controlled through I2C or UART interfaces. It uses a single 9 pin Hirose DF13 connector for interfacing to the host system. The mating connector is a Hirose DF13-9S-1.25C with crimping contacts DF13-2630SCF (tin) or DF13-2630SCFA (gold).
4.2.1 Backboard LEDs Five LEDs are mounted to give visual feedback on the sensor. Table 2 lists the functionality of each LED: LED Description PWR (orange) Power indicator, on when 5V connected Rx/Tx (red/green) UART receive and transmit indicators LED 0 / LED 1 For internal use only 4.2.2 Electrical characteristics DC electrical characteristics Parameter Minimum Typical* Maximum Power supply Voltage input (V) Current consumption (mA) 4.75 130 5 *180 5.
The TeraRanger Evo is ‘free running’. This means that it will restart a new measurement as soon as the last one is finished. The displayed data via I2C protocol is always updated at the end of a measurement. Nevertheless, it can always be read at any time.
CHANGE_BASE_ADDR[1] 0xA2 Write this value followed by the new address to set [2] , eg. send 0x42 if you want the Evo’s base address to change to 0x42, ignore Read/Write bits. Wait at least 1 second for the TeraRanger Evo to rejoin the I2C bus with the new address. 1] This command assigns a base address that will be memorised by the TerRanger Evo ie. power cycling the Evo will not restore the default I2C address. [2] Valid addresses accepted by the TeraRanger Evo are in the range 0x02 to 0x7F.
