Hardwiring ring gen2 keypad from existing wiring

Hi everyone,

I’m running into an issue that hopefully someone can help out with. I’m trying to use my existing hard wiring from my old alarm keypad to power the ring one. I’ve purchased one of the adapters on amazon (https://www.amazon.com/gp/product/B07RDGR9GF/ref=ppx_yo_dt_b_asin_title_o09_s01?ie=UTF8&psc=1) but I must be doing something wrong. My existing cable has four wires - red, black, green, and white. The youtube video (https://m.youtube.com/watch?v=3NA7jktxp9M) instructions had existing wiring of red, black, green and yellow rather than white. In the video the guy just capped the green/yellow together, and connected red to red and black to black, which is what I tried, and I capped the green/white together. I attached a picture of how I tried setting it up but I’m getting no power out of the end of the micro usb.

In my previous alarm, both the red and black were screwed into the keypad into a slot that was labeled 14VDC [+] (2) and both the green and white were screwed into a slot labeled 14VDC [-] (2) if that helps for extra context.

What am I doing wrong with the green and white wires? Thanks in advance!

Well, if what that panel said is true both red & black are positive, so you may need to use red & white. But before you hook that up you should test with a voltmeter. If you get 12 volts across the pair you should be good.
