The Dart, Dart2, G62 LTE & LoRaWAN and G100/G120 models all have 200mA fuses installed on the PCB for external power inputs. Digital inputs (including ignition) and switched
ground outputs do not have integrated fuses, and are not specically required by design, but may be installed to protect against external wiring faults.
The Fuses are self-resetting and do so when the fuse cools down. If the fault that is causing the fuse to trip is still present, it will require the device to be removed from power sources.
This means that the installer does not have to set up their own fuses for the device..

Wiring Harness
Pin # Colour Function Notes
1 Red Voltage Input 8-36 Volts DC External power
2 Black Ground Main Ground
3 White Ignition 0-50 Volts DC, permanent internal pull down
4 Blue Digital Input 1 0-50 Volts DC, congurable pull down
5 Yellow Digital Input 2 0-50 Volts DC, congurable pull down
6 Brown iButton iButton input
7 Green Switched Ground Output Low side Switch. Use with a relay, LED or buzzer
Default Parameter Settings
The G62 will operate with default settings out of the box. These can be changed using the OEM Admin interface. The defaults include:
Hourly Heartbeats: the device will log a heartbeat record, connect to the server, and refresh its GPS data every 60 minutes.
Wired AND Emulated Ignition: by default, the G62 will track a trip if either the ignition wire is pulled high or movement is detected. The setting can be changed to do one or the
other, or continue to use both.
Inputs: inputs are pulled up internally and are active low. This means you can connect pull to ground switches or contacts. The bias can be set to pull up, down or neither. They
can be set too active high or low and the debounce can be changed.
Output: the output is not used by default
Default I/O Mappings
Digital inputs, analogue inputs, and various 'statuses' (e.g. GPS interference detected) can be mapped to device Digital inputs
The G62 has the following digital inputs mapped by default, it is important to keep these in mind when mapping inputs to avoid clashes.
Digital Inputs
DI Number Meaning Comment
0 Ignition
1 Digital Input 1 Physical digital input 1 is mapped here by default, but
it can be remapped elsewhere.
2 Digital Input 2 Physical digital input 2 is mapped here by default, but
it can be remapped elsewhere.
5 GPS Interference GPS Interference indicator is mapped here by default,
but it can be remapped elsewhere
6 GPS Jamming GPS Jamming indicator (signal lost) is mapped here by
default, but can be remapped
Driver ID Options
The G62 can use the Dallas iButton readers as well as MiFare, EM4001 125kHz and HID cards. See here for more Driver ID options.
