CV Description Range Default
#211 DCC
basic
/DCC
ext
mapping for 1R, Signal 1
This CV can be used to set which signal aspect should be displayed after a DCCbasic swit-
ching command “1 Red” on signal 1.
255 = Specication in accordance with signal conguration
The DCC
basic
switching commands display the signal aspects as predened in the signal
conguration of the signal decoder selected via CV #41.
0 … 254 = Explicit specication through user
If you wish to avoid specications in the selected signal conguration, then you can enter
the DCC
ext
value here which accords with the required signal aspect. An explicit speci-
cation by the user may be expedient if, for example, the DCC system used does not yet
handle any DCC
ext
switching commands, and/or any switching sequences already available
for signals deviate substantially from those in the Z21 signal DECODER. In this case, the
Z21 signal DECODER can be adapted highly exibly to the existing system.
Example: CV #211 = 16 (“Clear to proceed”) … Signal 1 then displays, after a DCC
basic
switching command “1 Red” the signal aspect “Clear to proceed to”.
You can also nd the valid DCC
ext
value range as well as the predened assignment for the
DCC basic switching commands of your signal in Appendix A – Signal conguration “Uni-
versal” or under the link provided in Appendix B – Signal congurations.
For explanations on the DCC
basic
and DCC
ext
switching commands, see also the section
Operation on DCC control centres.

6.4 Resetting to factory status
If you want to set all settings back to the original status condition, keep the programming button held down until all LEDs are lit and
the blue LED is ashing. This means that all settings are reset and the reset has been initiated.
Alternatively, the value 8 can be written back to CV#8.
