Dart - Getting Started

The Dart is a compact 2G or 3G tracking device. It is designed to provide extremely cost effective tracking with all the quality and support of a Digital Matter product. It includes the latest GPS and cellular technology to give excellent performance at an entry level price. 

In the Box

You'll get a compact box containing the Dart and a 12 wire harness. Note that OBDII and Cigarette Lighter harnesses will be options in future

Installing the Sim Card

The Dart uses a Standard SIM card–form factor 2FF.The SIM holder is on the top of the PCB. When handling the Dart be careful not to touch the GPS antenna, to minimise the risk of damaging the sensitive GPS amplifiers with static discharge.

  • Unlock the SIM holder by sliding it towards the harness end of the device. Tilt the holder up on its hinge.
  • Insert the SIM with the contacts down and the keyed corner pointing away from the harness end of the device
  • Put the holder back down on the PCB and slide it away from the harness end of the device to lock it in place.

To easily get up and running:

  • The SIM should not have a PIN on it, unless you use the device specific PIN.
  • The SIM should have credit or airtime
  • The SIM should use one of the APN's built into the firmware. Otherwise contact DM about APN setup. It is possible to set APN's by SMS

Connect the Battery

The Dart comes with a 400mAh battery

  • Leave the battery in the position it is stuck down, away from the antennas
  • Plug the battery into the socket shown in the image
  • The LED should start to flash.


Getting Online

Once the battery is connected, the internal LED will come on and flash blue and the device will do the following:

1. Connect to the server: If the SIM card works, the device will connect to the OEM Server. It will attempt to download any firmware and parameter updates and fetch fresh GPS aiding data.
2. Get a GPS Fix: the device will attempt to get a GPS fix. Speed this up by moving to an area with good GPS signal.
3. Reconnect to the server: The device will attempt to connect again to upload the result of the GPS Fix.
4. Stop flashing: once complete, the LED will stop flashing. If the device does not complete these steps in 10 minutes, it will go to sleep and try again on the next heartbeat or the next trip start.
5. If the battery is too low, use the harness to provide external power.

Go to www.oemserver.com/installer to search for the serial number. Here you can confirm that it has connected recently.
If the LED flashes but the Dart does not connect, check the SIM is in the holder correctly and check that the SIM is working.


Opening and Closing the House

The housing closes with clips and does not need screws

To close the housing, line up the top and bottom parts. Push the housing together firmly.

To open the housing, insert a flat screw driver into the opening highlighted below. Carefully lever the two halves apart.

Default Settings

The Dart 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 Dart 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
  • Driver ID: The Dart RFID reader is enabled by default.

Driver ID settings

The Dart can read RFID tags using the Dart Driver ID reader. This is different to the CAN RFID reader. The Digital Matter RFID reader is enabled by default.

Dallas iButton readers can be used with the Dart. Configuration setting should be changed on the OEM Server
