A method for setting up and/or updating the programming of a second control unit of a transportation device includes operating a first control unit of the transportation device in a first functional scope for setting up and/or updating the programming of a second control unit of the transportation device, setting up or updating the programming of the second control unit by the first control unit, and setting up the first control unit for a second functional scope. A system by which the method of the invention may be implements is also described.

A system, method and control unit for determining an order of a plurality of stacked electronic devices randomly ordered in a stack, for taking inventory of the devices, and for programming the devices according to the determined order. Each of the electronic devices is assigned a unique serial number, and the electronic devices are configured to report their serial numbers to the control unit in sequence, either upward or downward, in the stack. The control unit is configured to determine an order of the plurality of electronic devices in the stack based on the sequence in which the identifiers are received, to compare the sequence numbers to a known list to determine if any devices are missing, and to program the devices according to the determined order.
