Hi Kurt,
I've got the buttons connected and am able to scan, and actually find, the other modules.
I'm still a bit confused about the function of the buttons and the structure of the menu. But I'm sure you (or Zenta) can clarify it for me

The 4 buttons are marked X, Y, Y and Z. If I got it right the layout is:
bit 0 = W = esc
bit 1 = X = enter
bit 2 = Y = down
bit 3 = Z = up
Here come my noob questions:
If I'm in the home screen and push the down button I loop trough the following entries
home -> Cal Joystics Move Full Ranges -> Current My: 0000 -> Current DL: 0003 THEX New: -> Select By Name -> Right: 128 128 ->home
homeHome screen showing normal values
Cal Joystics Move Full RangesHow does this work? I can move all joysticks, buttons but nothing happens. Only if I hit X (enter) I get *** Error ***s
Current My: 0000This screen is a bit mixed up. I've got a lot of non-ASCII chars in there. No idea why. Maybe it is reading something for memory which is corrupted?
Current DL: 0003 THEX New:This shows the current selected XBEE module. Can it do something else? What's the "New:" for?
Select by nameThis is where I can scan for modules and select the XBEE module
A - Scan modules
D - Delete
RJoy - scroll found XBEE modules
Enter - Select XBEE module
Right 128 128What does this menu item do? It seems to show the left or right joystick values. Both my left and right joysticks are not totally stable in the home position so this screen keeps jumping between left and right.
Thanks! Xan
