Please clarify this, because i find it confusing.... i looked at a L5512RVF today whilst visiting a mate who is about to do a c-bus job with v3 for first time. i thought ok lets try programming from the database, even thought the unit was not connected at this time.. There is a 'field' to manually enter the bar code/serial number from the side of the box..... on the unit he had there were 13 digits on the barcode 9 311554 336899. the field only allows 12 digits. Ok i thought, maybe the 9 at the beginning is redundant... so i deleted it, to my surprise, the program accepted it but then automatically formatted the serial number by dropping the last 9 in the sequence , then adding a 0 at the beginning of the sequence. i started with 9 311554 336899 ended up with 0311554 33689. is there something i am missing or mis-interpreting ( quite possible on both counts).
