A DCC word has 8 binary bits or 255 different values in a data word. The NMRA RPs are written using the binary representation. Now just to confuse you a little more there are two common methods for numbering the bits in binary. Consider the Decimal number 3 which is represented by 00000011 in binary. Lenz counts the bits from 1 to 8.
Translation is easy.
Just add one to the NMRA bit positions to achieve the Lenz notation or subtract one from the Lenz bit numbers to achieve the NMRA notation. English Some systems use buttons, sliders, knobs, or menus to enter values. The positions of these buttons, sliders, or knobs are converted by the command station into the proper binary representation. To program other decoders on these systems it is best to understand what these various buttons, sliders, or Knobs actually do. The System One family as well as most computer based programmers use menus to help guide the user in selecting the appropriate value.
