How do I connect a start/stop button to the DL1?

The "start/stop" button gives the driver the option of starting/stopping logging on the DL1 without having to press the button on the unit itself.

The Race Technology lighted start stop switch has four connecting wires,

Step 1: Connect the wires on the start/stop button to the black, block connector that is on the end of the DL1 power cable. Once the block connector is plugged into the back of the DL1, the orange writing on the unit will tell you where to put the wires:

Green should be connected to "Stat",

Red should be connected to "5v",

Blue should be connected to "Trig",

and Yellow should be connected to "GND".

Step 2: Once the button is properly connected, test that it is working. A red LED should light up in the buttons' centre to show when the unit is logging.

If you would like to connect your own switch, use a momentary on switch between the "Trigger" and "Ground" circuits.

To add a logging indicator light, put a 12v light between the "Status" circuit and "12V" or to vehicle 12v.
