Install the switch and wire the ground wire (black in pics above) to ground.  The wire with the 10K resister is the 5V In (yellow in pics above), wire it to 5V Ref.  The other wire connected to the Driver 1 resister (white wire in pics above) goes to an RCP Analog Input.

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.

Wiring

DriverSelectorSwitchAnotated.jpg

  • Solder the resister for Driver 2 between switch position 1 and switch position 2, down low on the posts
  • Solder the resister for Driver 4 between switch position 3 and switch position 4, down low on the posts
  • Solder the resister for Driver 6 between switch position 5 and switch position 6, down low on the posts
  • Solder the resister for Driver 3 between switch position 2 and switch position 3, up high on the posts
  • Solder the resister for Driver 5 between switch position 4 and switch position 5, up high on the posts
  • Solder the resister for Driver 1 onto switch post position 1, sticking up
  • Solder a 2 wires to the other side of of the resister for Driver 1. One wire for 5V in (yellow in pic above), and one wire for RCP Analog input (white in pic above)
  • Solder the 10K resister inline with the 5V wire (yellow in pic above)
  • Solder ground wire to the center post
  • Use heat shrink tube to protect the wires

Install the switch and wire the ground wire (black in pics above) to ground. The wire with the 10K resister is the 5V In (yellow in pics above), wire it to 5V Ref. The other wire connected to the Driver 1 resister (white wire in pics above) goes to an RCP Analog Input.
