Driver ID

Driver ID 1 and Driver ID 2 are used for various functions depending on configuration. Either:

  • Driver ID 1 and 2 can be used to connect a Digital Matter RFID reader (plugs in via the 4 way molex connector)
  • Driver ID 1 can be used as the iButton Data Line, and Driver ID 2 can be used as a 3rd Digital Input. This can be independently or simultaneously.
  • Driver ID 1 and 2 can be used to connect Wiegand Driver ID readers

Molex Connector:

PIN 3,4,9 and 10 goes to to the 4 way Molex connector.

The four way Molex connector comes as part of the 12 way harness, with pins 3, 4, 9 and 10 from the main harness going to the connector. This can then be used for a plug and play connection to the DM RFID reader.

Connector Details:

Some partners may choose to build their own harnesses, or fit a suitable mating part to the 4 way molex connector to their own RFID readers to simplify installations.

To assist with this, part numbers of the connectors on the Dart3 wiring harness are shown below.

Plug and Play Connection Options:

We also have an OBD harness or a Cigarette Lighter harness options available. 

Please note that you will not be able to get an ignition trip if you are using either of these harnesses, since a dedicated ignition wire is only available in the 12-wire harness. The device will work out trips based on movement or change in voltage.
