Changing the dimming port signal

Post by bkc6868 »

I have the RA star. Do I have to open the head unit to change the Jumpers? I need 0-5 own.

I see analog printed on board along with the channels but nothing about pwm and I don't see any jumper pieces

0-5V is right on the left side of where you saw analog.

You are correct. They are not populated.
Not everyone changes signal types and you are the first one that mentioned it.
I'll instruct my contract manufacturer to install them on my next build.
You can get them on any electronic store or pull them from old motherboards.

So should I jump every one of the 0-5v pins for pwm 0-5 volts?

Something happened and I'm no longer getting 5 volts from pins 1&2 and 5&6. 3&4 and 7&8 still work fine. I've checked and rechecked the Jumpers and settings on everything.

There are only 4 channels and not 8. Which channels are you talking about?

Yes that's how I know they aren't putting out the 5 volts but the others are

I'm assuming that the screen is showing 100% on those dimming channels on the RA* screen, right?
If so, The channels may have gotten damaged.
Can you check the voltages on these pads?
