Hey there,Hi everybody, I have a Joying 6.2 inch in my car and a SWC wired controller on left side of steering wheel, connected at KEY 1 wire. Today I bought another SWC control, wireless with receiver and placed on console, and I've installed on KEY 2 wire. To be fully functional for me, I want to set both SWC controls to adjust Vol+ and Vol-, but I can only set one of them with SWC settings app.
There is some way to set resistive parameters manually inside any .txt or .conf file?
Thanks in advance!
I also recently installed a second SWC to my unit. I installed it on KEY1 however. I'm not 100% sure on this (i'm making an assumption now) but i do believe that these buttons have the same resistance for what they do.
In case you didn't know, a set of SWC buttons are just completing a circuit with a resistor value per button so it's perfectly fine to have multiple SWC' on KEY1
So, long story short: Connect your secondary SWC to KEY1 instead, even if another one is already connected to it. The resistor values should be the same if in your case you want the buttons to do the same anyway.
If this method does make both SWC's work but you find that you can only program one of your SWC's at a time and loses the setting for the first. Then you will need to get a set of resistors and a multimeter. Take both SWC's out of your car and onto the bench. Connect one of them to your multimeter and measure each resistance value of the buttons on the first SWC and do the same for the second one. If these values are not identical then you will have to make sure they are by changing the resistance values of each button so both units have the same resistor value for each button.
You will have to do this by wiring in, or taking out (hopefully not) resistors. I recommend you use blue resistors (https://www.google.com/search?q=blue+resistors) because they have a tolerance of 1 to 2% whereas the beige ones around 5%
PS: make sure you connect your SWC to the ground of your unit directly.
