 | 
| 
 | 
 | 
 | This value is the manufacturer ID of the decoder, | 
 | 
 | 
 | 
| 
 | 
 | 
 | (Atlas=127). Writing the decimal number “33” | 
 | 
 | 
 | 
| 
 | 
 | 
 | to this Register will reset all CVs in the | 
 | 
 | 
 | 
| 
 | 
 | 
 | decoder to their  |

 | 
 | 
| 
 | 
 | 
 | EXCEPT FOR the speed step settings in CV67 | 
 | 
 | 
 | 
| 
 | 
 | 
 | to CV94. |

 | 
 | 
 | The long (also called extended) address, if used, | 231 | 
 | 
 | 
| 
 | 
 | 
 | is contained in CV17 and CV18. |

 | ||
| 
 | 
 | Several decoder properties are set with CV29. Changes | 
 | 
 | 
 | |
| 
 | 
 | are easiest if done in binary mode, but can also be done | 
 | 
 | 
 | |
| 
 | 
 | by adding together the decimal values (shown in | 
 | 
 | 
 | |
| 
 | 
 | parenthesis) for all the desired features and writing the | 
 | 
 | 
 | |
| 
 | 
 | total into CV29. (For an example, see the section | 
 | 
 | 
 | |
| 
 | 
 | Converting Binary Values of Individual Bits within a | 
 | 
 | 
 | |
| 
 | 
 | Configuration Variable into the Equivalent Decimal Value | 
 | 
 | 
 | |
| 
 | 
 | of the Entire CV.) | 
 | 
 | 
 | |
| 
 | 
 | The definitions for the individual bits of CV29 are given | 
 |

 | 
 | 
 | 
 | 
| 
 | 
 | Bit 0 | Locomotive direction: | 0,1 | 0 | 
 | 
| 
 | 
 | 
 | This bit sets the direction that the locomotive will | 
 | (1) | 
 | 
| 
 | 
 | 
 | move when told to move forward in digital (DCC) | 
 | 
 | |
| 
 | 
 | 
 | mode. | 
 | 
 | 
 | 
| 
 | 
 | 
 | 0 = locomotive’s direction is normal | 
 | 
 | 
 | 
| 
 | 
 | 
 | 1 = locomotive’s direction is reversed |
