1Getting StartedAll Gecko models have a 2-pin power port, 6-pin alarm/communications port, and a coaxialGPS aerial connection. From mid 2019 Gecko Blast & SMA models also have a 4-pin port foran external sensor channel. Gecko Compact & Rugged have a 19-pin sensor connection.Setting up your recorderThe two-pin connector is the power input to the Gecko. The default Gecko operating voltagerange is 11.5 and 24 Volts DC (useful for 12V DC battery over-discharge protection), but itcan be factory switched to extend the range to 7V to 30V DC at no cost. If the power isremoved then restored, the Gecko will restart using the saved settings.The Gecko only takes a few seconds to initialise the operating system after power is applied.If an SD card is installed, the recorder will start storing continuous data to the SD cardwithin seconds.The small gold coaxial socket is the connection for the GPS aerial. The GPS is crucial inmaintaining accurate absolute time to synchronise recordings from various instruments andmonitoring locations, but it also provides global position information. Simply screw the GPScable plug onto the threaded GPS socket until finger-tight.The Gecko Compact and Rugged is supplied with a sensor plug which you can attach to yoursensor cable. You can find the wiring diagram at the end of this manual. Align the keyedplug with the socket and push it on, locking it in place with the bayonet-style collar.At this point you now have a fully functioning recorder, but you will need to modify somesettings to suit your application. Setting a unique station code is an essential starting point.
