DriverID Selector Switch allows you to easily select which driver is driving so that you can quickly and easily see who was driving in the data later by looking at the DriverID channel. Just assign each driver a number, and tell them to turn the switch to their number when they get in.

Resistors (1ea): For switches with 2-6 positions:

DriverID Resister Voltage
1 2.4K (2.2K will work) 1.0V (0.9V if 2.2K used)
2 3K 1.75V
3 4.7K 2.5V
4 8.2K 3.25V
5 22K 4.0V
6 150K 4.75V
10K required for 5V voltage divider

For switches with 7-11 Positions:

DriverID Resister Voltage
1 1K 0.45V
2 1.5K 1.0V
3 1.8K 1.5V
4 2.2K 1.97V
5 3.3K 2.48V
6 5.1K 3.0V
7 8.06K 3.48V
8 16.9K 4.0V
9 51K 4.5V
10 1M 4.95V
11 16 Ohm 0.0V (If you need an 11th driver move this to Driver1 and all others down one position)
10K required for 5V voltage divider

You can get these resisters from Digi-Key.com and search by resistance. Try to get as close as possible.

If you get different resisters than ones above, you can use this link to figure out what the output voltage will be. Set Vs to 5V, R1 to 10K. For R2, take the resister you have and add all of the resisters before it, to get the total resistance. It will calculate Vout for you. Use this to map your sensor inputs in Race Capture App.
