10. Programming/ reading CVs
SERV PROG / OP PROG
The MXULFA not only is a module too update ZIMO decoders, but also to read-out and program CVs.
The MXULFA provides two ways of communication with the decoder:
-
PROG
ramming on the
SERV
ice track: the decoder connected to “Schiene” responds with motor pulses
to requests by the MXULFA. This method is slow, but in many cases effective.
-
OP
erational
PROG
ramming: more than one decoder can be connected to “Schiene”, but only the de-
coder selected by its address will respond to the MXULFA’s request. This method is also called PoM (Pro-
gramming on the Main).
To activate one of the programming modes, press and hold the
R-key
(3 sec) to open the menu, scroll to
“SERV PROG” or “OP PROG” and press the
R-key
to change to the programming method.

11. Read / program load code
The load code for sound projects is one of ZIMOs specialties, which originates in a number of sound pro-
viders. They produce sound projects for ZIMO sound decoders. To load these sound projects onto a de-
coder, you have to buy a “load code”. This not only depends on the sound project’s author, but also on the
identification number of the decoder.
It is a simple process:
- Read out the decoder ID: CV values #250, 251, 252 and 253.
- Buy a load code (ZIMO homepage, retailer, sound project’s author): 4 three-digit numbers.
Program these values into CVs #260, 261, 262 and 263.
- Load the sound project into the decoder (see chapter 6).
To read and program the necessary values, the MXULFA provides the possibilities already known from
chapter 9 “read and program CVs”: "PR SERV ID+LD" or "PROG OP ID+LD".
Entering one of the programming modes via the menu: press and hold the
R-key
(3 sec) and select
"SERV PR ID+LD" or "OP PR ID+LD" with the scrolling wheel.

OP PR ID+LD
OP PROG After selection by
R-key

Enter addr:
the R-key the ID is read out automatically.
Otherwise, this procedure is identical (but faster) to the mode “SERV PR ID+LD” (see previous chapter).
