8.4.2 CV programming (byte) 
Use the “CV-Prog bytew” menu to program DCC decoders with 
1024 configuration variables (CV). 
This type of programming is also known as “Direct Programming”. 
The process takes up to 5 seconds. 
The programming menu will show the following display: 
Input the number of the desired CV (1-1024) in the left-hand column 
and its value (0-255) in the right-hand column. 
Programming and reading procedure: follow what was described in 
section 8.4.1 about register programming. In this section, please 
take special notice of the highlighted paragraphs. 
8.4.3 CV bitwise programming and reading 
Use the “CV Prog bitw” menu to program DCC decoders with 1024 
configuration variables (CV). With this programming method you 
can easily read or write single bits in a CV. This is really useful 
when each bit in a configuration variable has a special meaning, 
usually controlling different decoder options. 
The programming menu will show the following display: 
The menu has three columns. The left is used to input the CV 
number (1-1024), the central one to input the desired bit number (0-
7) and the right-hand column to input the bit value (0 or 1). 
Bits are numbered 0 to 7. Some decoder’s manuals (e.g. Lenz) use 
numbers from 1 to 8. Don’t forget to convert these values before 
using this menu. 
Programming and reading procedures: follow what was described in 
section 8.4.1 about register programming, with the exception that 
the reading procedure is initiated from the central column. 
If the decoder cannot accept direct programming, the display will 
display “Error” to indicate that the decoder cannot be programmed 
using this method. 
Changing the desired bits can still be done in the “Bytewise CV-
Programming” menu. (see Appendix). 
8.4.4 Paged programming and reading 
Use the “Paged Prog.” menu to program DCC decoders with up to 
1024 configuration variables (CV) which are programmed in paged 
mode.
