It's been too long... I need some assistance here (probably very easy)
I am connecting power plugs (wall warts) to the switched power outputs on my amplifiers so my HA system (HomeVision Pro) can tell when various amplifiers are on or off.
My digital inputs accept +/- 30V DC. All of my plugs work fine except one... when it is turned on, it gives my 8.4 VDC, but when I check my log - my HVPro is sensing very rapid switching from a signal to 0 (so it thinks it's turning on and off about 10 times per second) (HVPro detects anything less than 1.1V as a 0, and anything above 1.3 as a 1 (on)).
I have checked the plug straight off a wall outlet (to make sure the amp outlet wasn't bad) and it gave me the same result. I also checked it into another input on HVPro (to ensure the input wasn't bad). If I check the signal with a DC voltmeter - it's a nice steady 8.4 VDC.
Can I mount a capacitor in series to smooth this signal out? If so, any suggestions on the size of it? Any other ideas? I know... I could go buy another wall plug and be fine... but now I want to know why this one isn't working and how to fix it!
thanks!
