MTS Onboard Decoder
Programming functions
You can program numerous func-
tions of the onboard decoder to suit
your requirements. If you want to do
this, program the "function values"
in "registers" (CVs) using a PC and
the 55045 MTS PC Decoder Pro-
gramming Module. You can also pro-
gram the function values using a
55015 Universal Remote.
Hints:
- For normal operation, it is not nec-
essary to change the function val-
ues.
- If programming results in unsatis-
factory operation, you can repro-
gram the factory pre-set values of
most important CVs: Program reg-
ister CV55 to function value 55.
This also reprograms the loco
address to the factory pre-set
value.
To reprogram the factory pre-set
function values with the 55015,
select programming mode "P" (dis-
plays shows "P --"). Then input 6, 5,
and 5 and press the right arrow but-
ton. The display shows "P --" again:
Input 5, 5, and 5 and press the right
arrow button again.
