Hi fellow builders

I recovered a working bendix KX155 NAV/COM from a helicopter and I want to put it in my stampe to use on COM mode.

I wanted to bench test it but powering it doesn't even light the display. Does anyone know which pins have to be connected to even light the display? I attached a screenshot of the pins, note that the right plug is optional and not installed here.

I put +13.8V on 14+R and ground on 15+S. So what else?

Any help is appreciated.

Thanks
Simon
