FAQ:Addressing Conflicts between DCC Systems

|DCC Categories||DCC, Command Station|
There can be conflicts between address modes and DCC systems.
A common one is a restricted range: Lenz restricted their Primary Address range to 99. Some low cost, basic DCC starter sets limit the total addresses to ten or less. Which is perfectly acceptable, providing that limitation is clearly identified on the package and in the instructions.
Another is how the manufacturer interpreted the Extended Address range: Most use 128 as the beginning of the Extended Address range and their software works according. NCE allows values between 1 and 127 to be used as Extended Addresses, whereas most other manufacturers do not.
Digitrax's implementation of Extended Addresses ends at 9985, many other DCC systems allow addresses up to 10,240.
Conflicts usually occur in the Primary Address space, either caused by the limited range or the use of those addresses as an extended address.
