NavWorx Shield Grounds

For those of you who have installed the NavWorx box, where / how did you attach shield grounds to the 'funky' shell that ships with the unit? I've got a gaggle of shield grounds from the encoder, GRT display, maintenance serial port and ARINC to my 430s and unlike the G3 connector there is no where I can see to attach the shield grounds.

Thanks..

Generally speaking the shields shouldn't be connected at all at the far end. Connect them to a common ground at some point behind the panel. This requires that the "return" line be inside the shielded cable.

I just grounded them to a mounting screw of the box

You can use a solder sleeve to add a wire to extend the shield to be connected outside the d connecter. Like bob mentioned only connect one end. All my shields are terminated at the panel end. It's consistent and easy to remember.
