Using ALP Radio Mute and Control Functions

[ApexOnYou]

Well as it's a DC power sys. source,"Impedance" isn't the issue & checking for that won't tell you much.In your situation,actual "resistance" is the cause from poor bonding between the common ground connections is.

Correct. I used the wrong terminology in my post but if you caught that then you know what I meant. I will post resistance to ground measurements tomorrow.

For those curious of what the unit is doing:

Off:
Green: 16.3kΩ / 0v
Blue: 1mΩ / 0v

Standby:
Green: 105kΩ / 0.11v
Blue: OL / 4.67v

Alert:
Green: OL / 5.13v
Blue: 105kΩ / 0.11v

No change on any of the outputs when I did a short press of menu for "fog light" activation. I assumed one of them would be switching 5v? I was hoping to power my radar detectors off of this eventually.

But you can run relays off of either one using a few different methods. I am curious to see what BRD has been doing for this but for the time being my solution would be a 5v relay with a "relay driver" to buffer the circuit (without knowing what the ALP ouput can handle). You could also do something with a transistor switching a 12v circuit but I would just be copying off google since I haven't built one of those yet.

Apex , get this and you wiill be fine ,it works on 12 volts :

The 5v version of that should work. I'm not running anything off a relay, I was just curious to learn what the unit is doing and thought I'd share my findings.

My ver2 hardware bought in May/15
Using ApexOnYou Post #22 as a reference
Standby:
Green: 0v
Blue: 4.65v

Alert: (3sec LID)
Green:0v
Blue: 0v

15 sec after Alert! (great for a radio mute)
Standby:
Green: 0v
Blue: 4.65v


Conclusions:
1. Blue radio mute wire gave a signal when it saw an alert, green did not
2. Blue wire signal lasted 15sec
3. Problem Definition: Why did Green wire do nothing, yet my manual says "Green relay wire in the Rev2 ALP control box can be connected to the coil of an automotive relay which is then pulled to the +12v car battery. By using this relay it is possible to switch off/on other vehicle circuits during an alert from ALP. The relay wire pulls to the ground when active the same as the mute wire."
4. Diff topic, my 3sec alert keeps saying "...interference detection ONLY"...yet my 4sec LID timeout gives a nice machine gun sound, of course I am in blue mode.

Relay wire is a Ground not a positive trigger, Its used only to trip a relay for external options. For example some dealers install seat vibrators when alerts go off to get drivers attention.

Careful w/ that recommendation...we don't want women getting out-of-control & causing an orgasmic accident !

That would be interesting press article : '' i save my mariage thanks to laser alerts '' !

Why not?

Why not?

...b/c it might stain the car seat ?
