Phoenix Gold Phorum

Does anyone know if the new RMD will plug in to the old white ZX amps? Just looking at monitoring and thought this would be an easy fix.

this should have to help you out..... you have to make a new connector.....

the zx series don't have a standard rmd out .......

I can also show you how to do it with a relay if you do not want to hack up the cables.

That would be great, whats a relay by the way!?

Hey love that camera rail you made and the slow looks nice and moody

Cliff notes - Its an electronic switch that are used all over cars. If you break it down to its componants its a fairly simple device. There is an electro magnet that produces a field when energized, and when it does it pulls the switch open/closed depending on what contacts on the switch you use. If you look on the bottom of the relay you will see 4-5 pins depending on what style its is, but generally 5 pins. If you look on the plastic that the pins stick out of you will see small numbers designating which pin is what. I don't know why they picked the numbers they did but they are as follows
pins 85 and 86 go to the coil/magnet. Energize these two wires(doesn't matter which is +/-) and you will hear the relay click as the coil pulls the switch
pins 30/87/87a are all related too the switch. When the coil/magnet is not energized pins 30 and 87a are common/connected and when it is powered then pins 30/87 are common/connected.

So for you, you need to connect a wire to a +12v switched wire(behind the radio is a good place) and connect that to either pin 85/86. Again it doesn't matter what ever other pin you do not use will then go to a ground source. Now run a pair of wires from where you will put the relay, back to where the amp is and connect them to the ground/power connections on the amp or find the +12v/ground on the rddp wires. Connect one of these wires to pin 87 on the relay(Doesn't really matter if its the +/- but lets connect the + wire). Now from your rmd with the +/- connections on it, connect the + side to pin 30 on the relay, and then the - from the rmd to the remaining - wire in the pair that you ran from the amp to the relay location. With this set up you will read the amplifiers voltage as long a the key is on no matter if the radio is on or not. It will turn off with the key.
