Fichtelbahn OpenDCC BiDiB LightControl V1.3 Manual page 6

By every new start the appliance explains the following examination:
He looks in the user signature area whether already a serialnumber exists.
If no serialnumber is available here the serialnumber from the EEPROM is filed and the assembly begins
starts to work. If there is in the USERS signature area already a serialnumber available the new-struck up
serialnumber is rejected by the EEPROM and the already deposited serialnumber from the user signature
area is used.
The deposited serialnumber in the USER signature area is also preserved with a CHIP ERASE and can be
deleted only with a USER signature ERASE.
If you must change the serialnumber on a BiDiBus suited Device, it works only with a previous USER
signature ERASE.
However, this also entails that available calibration values get lost because these are also stored in this area.
This should not be done without a special reason.
I have deleted the printed serialnumber by mistake.
How can this be uploaded again?
1. You load a new serialnumber with the generator and upload this after deleting the USER signature area
to the BiDiBus Device.
Importantly: Now do not forget to replace the existing sticker by the new Unique-ID. Link to to the
generator: http://www.opendcc.de/elektronik/bidib/opendcc_bidib.html
2. You want to use the available (printed) Unique-ID again because it was already deposited in the rail
trackplans of my PC programms.
In this case contact Fichtelbahn-Support with the information of the printed Unique-ID number and
the accompanying hardware-serialnumber.
This works only with preequipped SMD kits! With independently loaded serialnumbers you must look in
the history of your loaded serialnumbers in the generator, for the suitable number.
