Why?
In order to reduce construction time by a FREMO-meeting, the setup of the DCC hardware has to be simple and easy to operate. Therefore it is an advantage if locomotives not has to be reprogrammed on meetings, specifically to ensure that the two locomotives has the same address at the event. Therefore, it is obvious to agree on a system where all long addresses uniquely assigned to a vehicle.
Scale Size?
Stock with different shell, which of course does not run on the same modular construction during an event, may of principle have the same addresses, so that addresses in the different scale´s are distributed independently.
Which long addresses do we distribute?
| Address Area | Application |
|---|---|
short addresses | Used exclusively only when a decoder with a long address can not be used. An allocation plan exists so far only for H0-Europe |
| 0000..0199 | Is not used, since it only create confusion with short addresses in the range 0...127 and since the protocol used for LocoNet, can not distinguish short and long addresses. |
| 0200..0299 | Is reserved for technical play. However, it is not 100% in clear, whether we should use it, but sometime in the future equipment can be developed, which can only use certain addresses. Since this equipment is likely to be used by several groups, the addresses are reserved for all groups. Distributed worldwide addresses:
|
| 0300..9979 | Available for loco dekoder, distribution managed by each scale group. Currently there are nine groups who independently allocate long addresses:
|
| 9980..10239 | Not used because they can not be selected from a DT100. |
