gps on can port not working

Hello,

has anyone experiance with conecting a here2 gps via the can port?
I use a pixhawk 2.1 with an orange cube on copter 4.0
but when i conect the gps with the switch set to can the cube doesnt reconize it.
is there a parameter that i need to adjust to make it work?

kind regards

Also remember that the Mag will be listed after the internal ones with CAN so you shoud used the mask to disable any internal ones first.

There is a video on this on YouTube I put up on Here 2 Can.
