The latest Darts supports two forms of Driver ID input:

  1. (Default) DM RFID Reader: the reader plugs into the Molex connector and reads 125kHz RFID cards. There is an LED and buzzer built into the reader. Plug the reader into the plug and ensure the the 4 wire connector function in system parameters is set to DM RFID Reader. Note that this is different to the CAN RFID reader used on other products (G60, G100...)
  2. iButton Reader: the TTL Tx and Rx lines can be joined and connected to a Dallas iButton reader. This allows the system rail output to used for another purpose, such as LED in the reader - be sure to use a series resistor. Connect both Rx and Tx to the iButton reader's positive line. Connect ground to the iButton readers negative line. Ensure the the 4 wire connector function in system parameters is set to iButton. The 4 way Molex connector may need to be cut off if the iButton reader does not have a corresponding Molex connector.

Note: there was a small change on the Dart to accommodate the iButton readers. This was made in August 2016. It should be usable on Darts with serial numbers greater thanĀ 122000.

In the system parameters on the OEM Server, the following sections are important:

  1. Driver ID: this setups up:
    1. Buzz on no Driver ID: if a trip starts and a Driver ID tag has not been scanned, sound the buzzers. Buzzers may be external via the digital output or internal to the RFID reader.
    2. Immobilise: if Yes, immobilise via the digital output until a Driver ID tag is scanned.
    3. Expire on Trip End: immediately expired the Driver ID when a trip ends. Otherwise, use the expiry time.
    4. Test Against List: if Yes, ensure any scanned Driver ID tags are present in the Driver List. If set to No, allow any driver.
    5. Expiry Time: how long, in seconds, a Driver ID remains cached after scanning. If a trip starts while cached, it is kept until the end of the trip, or until another tag is scanned.
  2. 4 Wire Plug Function: specify if the RFID Reader or iButton is being used.
  3. Power: should the system rail output be turned off when the Dart goes to sleep.
  4. System Rail Output: what the system rail output wire is setup to do. If used with an RFID reader, ensure it is set to "system rail output". If used with an iButton reader, it can be used in different ways. For example set it to LED and connect it to an LED in the reader (don't forget the resistor in series).


The Dart has a 4 way Molex connector on its wire harness. This exposes 4 functions in the wires that are currently used for the 2 purposes described above, The wires are:

  1. System Rail Output on Purple: 4.7V output when connected to external power. Battery voltage output when running on the battery.
  2. Ground on Black
  3. TTL Tx on Brown.
  4. TTL Rx on Green.
