    Re: Gables Audio Panel Wiring

    Too Bright......? Maybe thats why my face looks sunburn after I connected the 12V supply?

    Anyway, I appreciate the information and will look into reducing the voltage to see if still works.

    I also got the Pin configuration for the Gables Audio, but im not sure how to read it. Not sure if anyone has ( or knows) the standard pin layout but at least this is a starting point. I also referance 5V for the power supply.

    Re: Gables Audio Panel Wiring

    Take a pic of the connectors.
    Also you might find on them a catalog no for them and find
    the pin out.
    If it's the round connector which usually you can find on AC, then 1 is in the mid, then it's spirals out bound.
    Usually there is numbering of the the first pin with circle on the inner side and numbers on the outer side (where the wires connect).
    Hope I remember this correctly, as it's been over 20 year since the last time I work with those type of connectors.

    Re: Gables Audio Panel Wiring

    Hessel,

    I can read the numbers on your left set of pins;

    #1 is dead center, and you count in a clockwise fashion around the spirals.
    If you look, you will see there is a road, and occasional they even put a pin number down. I colored in the path in red to show.

    Unfortunately, the back of your audio has a slightly different pin arrangement than mine does but I will try and snap a photo and upload here for reference.

    My Progress: Even with the pin wiring/arrangement handed to me, I ended up bypassing the pins for the audio on/off switches and wired them myself. If you open up the panel, each pushbutton actually has 2 micro switches attached to it, and I just tied into the available ( un-used) microswitch.

    Re: Gables Audio Panel Wiring

    Hessel,

    here is what the back of my audio panel looks like.
    For My J1 pins, the number #1 pin is in the middle and you simply follow the path as you move in a clockwise direction and ends at pin #55.

    For the J2 Pins, you also start in the middle, but the path moves in a counter-clockwise fashion and ends with pin # 24.



    I had trouble getting the Audio On/Off switches to work using the pins because they are wired in series. To get around this, I noticed each switch actually is made up of 2 switches ( one being un-used). So I soldered my wires to pin 1 and pin 3 of the empty switch and BING ....it works. Plus I dont have to worry about voltage being sent to my I/O cards turning them into a smoky mess.

    Below is a photo showing how to get access to these switches , at least on the gables that I have.


    Hope this helps.......
