Light Data/Light Action

I'm confused as to the selections under the above heading.  I'm using GF PMDG INTERFACE 1.0.42.0.  I,m trying to set up my T-8 for the light switches on the NGX.  I've got the taxi lights working by trial and error.  The landing lights have been giving me a problem.  I got the Switch Event to get them on and off, but I can't get the Light Data and Light Action right to have the light come on and off on the T-8.

I can see that configuring all the switches is going to take some time, cause there are so many choices to make and I don.'t know what 3/4 of them mean.  Is there a guide as to what all the selections mean and do?

Thanks Steve,

    Hi Gnacino,

    There are 4 events for the landing lights:

    The Fixed lights are:

    EVT_OH_LIGHTS_L_

    EVT_OH_LIGHTS_R_

     

    The Retractable lights are:

    EVT_OH_LIGHTS_L_RETRACT

    EVT_OH_LIGHTS_R_RETRACT

     

    The respective light data for the fixed lights are:

    DATA_BTMOH_LTS_SWITCH_LANDING_FIXED_LEFT

    DATA_BTMOH_LTS_SWITCH_LANDING_FIXED_RIGHT

    use a Light Action of "ON" and the Light Value of "1"

     

    and for the retractable lights:

    DATA_BTMOH_LTS_SWITCH_LANDING_RETRACTABLE_LEFT

    DATA_BTMOH_LTS_SWITCH_LANDING_RETRACTABLE_RIGHT

    use a Light Action of "ON_GREATER_THAN" and the Light Value of "0".

     

    Normally you just use Light Action of "ON" and "1", however the retractable lights have 3 positions and each position returns light data of 0, 1 and 2. Hence you need to test for the light data to be greater than zero.

    There isn't a guide as such. I have made some notes in the user guide which you should read, however most details are in the PMDG SDK. You can use notepad to look at the following file <flight sim directory>\PMDG\PMDG 737 NGX\SDK\PMDG_NGX_SDK.h. The file is programming code, but you should be able to see the lists of events and the comments next to them.

    Best wishes

    Steve
