Data Logger Layout
•Charging port –A micro USB connector to charge the devices battery, any 5v USB charging
device can be used to recharge this logger. Charge time is dependent on charger but maximum
charge rate is 500 milliamps, at this rate the unit will take just under 4 hours to fully charge.
•Spare Ethernet Port –This port is currently unused.
•Debug port –Micro USB Used to program and debug the data logger
•ON/Off Switch –turns the device power from battery on and off
•Charging Complete –This LED indicates that the battery is fully charged when on.
•Power On –This blue LED indicates the power is on when on.
•Battery Low –This LED indicates that the unit needs charging when on.
•GPS Status (not shown) –A solid red light means that the GPS receive is on but does NOT
have a lock, a blinking red light indicates a GPS lock.
•Unit Mode Select –The user presses and holds this button to select functionality
o1 Second Press (acknowledged with 1 audio beep) = Start new log, if one is already
running a new one will be started in a new file
o2 Second Press (acknowledged with 2 audio beeps) = Stop Logging
o3 second press (acknowledged with 3 audio beeps) = This requests that the unit sync
itself to GPS time when it is receiving the correct GPS data, even if the GPS light is
flashing it may take a while for this to happen. A long beep will occur when the unit is
sync’d.
•Unit Status –When a green LED is flashing the unit is logging, when a yellow LED is on it means
there is no Micro SD card detected.
•Micro SD Port –This is where the Micro SD card is inserted, the Micro SD card is where the
logger data is recorded to, it needs to be FAT32 and smaller than 32GB and have a ‘unit.cfg’file
created by the configuration GUI on it.
•GPS Antenna Connector –This is where the GPS antenna connect to the device.
