3.3V voltage levels, you need to use a voltage level translator. An I2C adapter for reliable
voltageleveltranslation is available from our website at:
http://www.teraranger.com/product/terarangeri2cadapter/.
In addition you have the option to purchase the TeraRanger Hub. This accessory board
allows you to connect up to eight TeraRanger One sensors and read the data from the
sensors via a single serial or USB link. See more at:

1.7 USB Interface
If you have purchased the TeraRanger One USB adapter, you can directly connect the
TeraRanger One to your PC without the need of any additional power supply. In most
modern operating systems, a driver for this interface is already present and the interface will  
appear as an FTDI virtual COM port to which you can connect using the settings that were
previouslymentionedintheUARTDataInterfacesection.
In case your computer asks you to provide a driver, please download the driver for your
operating system from http://www.ftdichip.com/Drivers/VCP.htm and follow the installer. After
successful installation, unplug the interface for a moment and plug it back in. The virtual  
COMportshouldnowbeavailableonyourPC.
Note: Do not plug/unplug the TeraRanger One from the USB adapter while the device is
powered,disconnecttheUSBplugfromthePCfirst!
1.8 Details on Supply Voltage
TeraRanger One works with clean, spike and interruption free voltages ranging from 10V to
20V and has an internal voltage regulator for optimal performance. However, to minimise
unnecessary heating, we advise the use of a preregulator down to 12V, and ideally 10V. For
optimal efficiency, this should be a switching regulator (either buck or boost, depending on
thesupplyvoltageavailableonyoursystem)withalargeoutputcapacitorandgoodfiltering.
TeraRanger One is equipped with a safety shutdown to prevent damage from excessive
currents or board temperatures arising from eventual internal failures due to incorrect
mounting, misuse or externally provoked shortcircuits. In case of shutdown triggering, the
sensor resets automatically after reaching normal working conditions and a power cycle of
theexternalpowersupply.
