    Making certain switches only work when others are made

    hi Alan and everyone, thanks so far for the great help with my Jaguar cockpit. What i`m trying to do now is to get the engine start selector to only work when the engine ignition is selected on and the APU is running, is there anyway I can do this with FS2phidget. I have already played with the expression editor but it doesn`t appear to make a difference.

    Thanks in advance again

    Chris

    Chris,

    If you are talking physical switches, you can maybe do some "physical logic" to cause this to happen.

    I have certain switches in my pit that only activate certain functions in the sim if a different switch is in the correct position first. This can be as simple as routing the physical wire that activates the actual function in the sim (keypress or whatever) through that second switch that must first be in the correct position (like maybe "start master set on") for the electrical pulse to reach the interface board.

    Use of multiple pole switches allows this to get more complex, like lighting an indicator for the position of the second switch in addition to allowing/blocking the keypress function, or having the second switch also "talk" directly to the in sim functions in ADDITION to controlling the pulse from the first switch AND lighting an indicator light.

    And so on.

    best,

    Chris,

    I was going to suggest simliar solution to John, but he beat me to the draw. Not often you see a Yankee do that to a Texan.
    John's suggestion frees up ports on the phidget card.

    Only thing is detecting whether APU is running. Is there an offset one can use? Don't think pmSystems supports Jag (yet), but it would be out of place for me to comment on behalf of Thomas.

    Assuming there is an offset. I would assign offset to a digital output and then run a wire in series from the output to the ignition switch and then to start switch.

    Regards,
    Alan.

    What can I say, this forum is the best and you guys are fantastic. When you think of the solutions logically they can turn out to be the easiest and most cost effective way of doing things. Thanks once again for all your help guys and i`ll let you know how it`s going.

    Regards Chris
