Gear up/down

[CABACO 0]

First of all I want to thank you for your help and ask for forgiveness for my English (I am Spanish)

My problem is the following. I made the landing gear myself for my 737 PMDG home cabin. I used several imternet tutorials and the electronic part was made with two switches.

They are connected to a master card in their respective inputs and it is to a USB Y card to the PC.

I have checked everything with sioc monitor and mark the entries well.

I have also tried the train with FSX the iFly737 and everything works fine.

The problem comes when loading the 737 PMDG. It does not work .... When raising the lever the red lights are lit for a second and return to the green and the train does not act.

I have tested with PMDG on FSX and P3D v4 and they do not work.

The script is taken from the opencockpit page.

I would appreciate your help ....

What may be happening?

Do you need something special to operate a simple switch with PMDG?

Thanks in advance and I hope your help ....
