DriverID Selector Switch

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.

Parts Needed:

1 pole Selector Switch (chose one):

Resistors:

You can use any value resister you want, but they all need to be the same value. Recommend 1k-100K range. You need total number of drivers - 1 resisters. Ie if you have a 6 driver switch, you need 5 resistors (all same value). If you have 4 driver switch, you need 3 resistors, etc.

Wiring

Solder a resister between each post on the switch.
You will need to alternate soldering the resisters low on the posts and high on the posts in order for them to fit.
The resisters that attach to the end posts will have to be low on the posts, so that you can also solder a wire to those posts as well and cover it with shrink tube.
It is easier to solder all of the resisters that need to be low first, then solder the resisters that will be high on the posts.
Solder Ground wire to switch position 1 post (black wire in pics above).
Solder 5V Input wire to last switch position post (yellow wire in pics above)
Solder Voltage Out wire to the center post, this goes to RCP analog input (red or white wire in pics above).
Use heat shrink tube to protect the wires

Install the switch and wire the ground wire (black wire connected to the first post in pics above) to ground. The 5V In (yellow wire connected to the last post in pics above), wire it to 5V Ref on the RCP (see below). The other wire connected to the (white or red wire in pics above connected to center post) goes to an RCP Analog Input.

Race Capture Settings

Edit the Analog input channel that you wired the DriverID Switch to. Click the gear icon and change the name to DriverID, set Precision to 0, Min to 0, and Max to however many positions your switch has. Set the Sample Rate to 1Hz.

For Mode, select Mapped. 0V gets mapped to 1. 5V gets mapped to however many positions your switch has. It will interpolate in between so you can just use those values. Here is an example of a 4 position switch,

Write the config to Race Capture and test the switch with the dashboard.

If it does not work properly, go back to the settings, change Precision to 2 and change the Mode to Raw. Write the config, and test again. Write down the Voltage for each position on the switch. If any do not match up with what is in the table above, go back and input that value in the Race Capture mapping table in an appropriate cell location. To get an idea of what the mappings should be, take the number of resisters you used and divide 5V by that number to get the voltage spread between the positions on the switch. The first number should always be 0V and the last should always be 5V, Rinse and repeat until you get it working properly.
