Find your desired address in the range of addresses in the table. Note the CV17 value in the adjoining column.

To calculate CV18, simply subtract your desired address from the first number in the range that your desired address falls in.  The value of CV18 will be in a range from 0 to 255 and can be 0 or 255.

 

YOU MUST ALSO SET CV29 TO 34 OR 38 TO ENABLE THE EXTENDED (4-DIGIT) ADDRESS!

A value of 34 = DCC operation only

A value of 38 = DC & DCC operation


Examples:

Desired address: 1234

Range: 1024 to 1279

CV17: 196

CV18: Desired address(1234). First number in range that your desired address falls in (1024). Subtract 1024 from 1234 to get CV18 = 210

 

Desired address: 6492

Range: 6400 to 6655

CV17: 217

CV18: 6492-6400= 92

 

Desired address: 9267

Range: 9216 to 9471

CV17: 228

CV18: 9267-9216= 51
