Programming the Decoder
Numerous functions on the decoder can be programmed
individually. To do this, function values are programmed in
registers (Configuration Variables - CVs). You also can pro-
gram the function values with the 55015 Universal Remote
Controller.
• For normal operation, it is not necessary to change the
function values.
• If programming results in unsatisfactory operation,
you can reprogram the factory pre-set values of most
important CVs: Program register CV 55 to function value
55. To reprogram the factory pre-set function values with
the 55015, select programming mode "P" (displays shows
"P --"). Then input 6, 5, and 5 and press the right arrow
button. The display shows "P --" again: Input 5, 5, and 5
and press the right arrow button again.
