Problem solved!

The IrDA (repeater) is not that luxury as the Xantech. I'm able to connect the transmitter with a connector on the Outlaw 950, but there is only one connector on the box.

So I checked the box by opening it.
There I saw 2 power LED's and 3 IrDA LED's.
I didn't know this and thought that the small IrDA LED was the only one and has to be connected on the (only) jack.

By removing this eye from the jack the 3 IrDA LED's are working and beaming all the info I need.

So I'm happy now.
Thanks for all the reply.
