How to change FCU Alt increment (100 or 1000)?

I can't find anywhere an offset or keyboard command to change the Airbus FCU Altitude selection to increment in 100s or 1000s.

Can anybody help?

Thanks,

I think you will need:

540A MCP/FCU Altitude Set (Write).

How you change tha alt setting in this window will depend on your hardware interface software.

I use fsbus. The value of the alt window is copied to a accumulator. When I turn the rotary cw or ccw 100 feet is added/subtracted from that value. The new value of the accumulator is send to the display and also to the sim.

Thanks, Norbert.

My rotaries are connected to the FDT boards so I think I will give them an email.
