Our YD8116 can be controlled either via “normal” DCC turnout addresses or via the relatively new DCCext format.

Briefly summarized, the difference:

With multi-aspect signals, switching via “normal” DCC addresses can become complicated. Different DCC switching commands must be combined in a certain time and sequence. This, of course, also consumes several DCC addresses.

If the DCCext format is used, only one DCC address is needed to control the different signal aspects for multi-aspect signals.
control. To the DCC address simply a value from 0 to 255 is sent. A specific signal aspect can be individually assigned to each value.

What is the advantage of DCCext?

• No complicated DCC address combinations have to be switched!
• The use of DCCext saves normal turnout addresses!
• Thus, as an example, for a DB H/V exit signal with four aspects, only one single turnout address is required, whereas conventionally two or more DCC addresses are required.
• Up to 255 switching aspects can be freely assigned.

For more detailed information, please refer to the RCN-213 standard. Please note that the command station you are using must support the DCCext format.
