NMRA CV 27 - Decoder Automatic Stopping Configuration

This CV is used to configure which conditions on the rails will cause the decoder to automatically stop.

Bit Option Value Default
0 Set to Enable Auto Stop in the presence of an asymmetrical DCC signal which is more positive on the right rail 1 OFF
1 Set to Enable Auto Stop in the presence of an asymmetrical DCC signal which is more positive on the left rail 2 OFF
2 Set to Enable Auto Stop in the presence of an Signal Controlled Influence cutout signal 4 OFF
3 [Reserved/Not Used] N/A
4 Set to Enable Auto Stop in the presence of reverse polarity DC 16 OFF
5 Set to Enable Auto Stop in the presence forward polarity DC 32 OFF
6 [Reserved/Not Used] N/A
7 [Reserved/Not Used] N/A

Note If the decoder does not support a feature contained in this table, the decoder shall not allow the corresponding bit to be set improperly (i.e. the bit should always contain it’s default value).
