    Gables Audio Panel Wiring

    I know this subject has been brought up before ,so I will apologize in advance ( couldn't find it using the search function) but............

    I just purchased a gables Audio panel ( 10$ on ebay!), and would like know what voltage is needed to activate the backlighting and which pins do I use?
    Also, for the other buttons, would it be easier to tear out the wiring and re wire it myself or use the pre-existing pins? The problem is that I dont have any wiring diagrams so I dont know how to tap into the current pin configuration on the back of the unit.

    Any advise?

    Thanks,

    Polmer

    The person who was our resident expert in this department doesn't seem to visit us as much as he used to.

    If anyone else knows the pins for connection please let us know i'd be interested myself.

    You might try for a service manual at www.gableseng.com/audio.asp sometimes manuals can be had by downloading a pdf file.

    Re: Gables Audio Panel Wiring

    Have nearly the same.

    Already tried the backlighting: 5 V DC.

    Re: Gables Audio Panel Wiring

    Progress:

    last night I have uncovered the pin combination to get the following Microphone switches to work:

    PTT
    Voice Only
    VHF-1
    VHF-2
    VHF-3
    HF-1
    HF-2
    INT
    PA

    I really need to get the volume (on/off) switches to work( have the arrow on them), and of course the backlighting would be nice too.

    I have tried the Gables site and have request access to documentation and will see where that takes me.


    will keep you posted.

    Re: Gables Audio Panel Wiring

    Polmer, how did you manage to find the right pins for what you have found there Must have taken a lot of work ... theres hundreds of possible combinations for each component right? And if you get one wrong it could damage the internal components anyway.

    Bravo to you for working so hard in finding the pins for what you listed.

    Re: Gables Audio Panel Wiring

    Well, yes it did take me several hours to accomplish this much.
    I didnt bother to put voltage through any pins since I didn't want to short anything out.

    This unit has 2 cable connections;
    J1= has 55 pins
    j2= 24 pins

    I turned on the switches then tested pins for a short.
    Once I got a short, I had to turn off each switch to find out which switch caused the short.

    Not sure how far I will get decoding the wiring, but will be glad to share what what I uncover when im done.

    Further Progress:


    I finally got the gables backlighting to work ( Thanks Udo).

    It takes 12 volts, and I bypassed the pins on the back, opened up the case and found several light posts with 2 poles. Connecting to anyone of these lights up the whole circuit and the backlighting comes to life. Polarity didn't seem to matter.

    I will get some pictures posted shortly.

    Gables Audio Panel Progress Continued

    As mentioned in the previous post, Udo helped me to get this panel backlight working.



    If you look carefully in the 1st photo, you will see the yellow arrows pointing to the points were you can connect a power 12v power source. There are several of these (nodes) available once you take off the case and look inside.



    I just soldered two wires to the 2 connections, then feed them off my PC 12V power & ground. The results show how it looks with the lights. Yes, the switches light up when selected as well........

    Re: Gables Audio Panel Wiring

    They look way to bright.. i can tell you this, in an aircraft (airliner)it is either 5Vdc 5Vac or 28Vac or 28Vdc NEVER 12Vdc.. The pnl i had that looked identical to yours was 5V and looked a very soft yellowish warm glow. Not im about to blow bright white. )
