You simply select the corresponding mode using one of the arrow buttons. These modes are
displayed as running text.

Confi rm with the Light / OK button. You will then be returned to the initial “MODE” level.
3.2. The “Programming” menu
All values of a decoder (NMRA / DCC) are stored in so-called confi guration variables, the CVs. You can
adjust these values to your needs using the “PROGRAMMING” menu.
Before a new value can be written, the current value is read from the decoder installed in
the locomotive and displayed. The read-out process can be interrupted by briefl y pressing
the Z21 Stop button. Decoders already installed in locomotives by ROCO are delivered with
practical settings. That is why you should check whether it is really necessary before doing
any programming.
Programming must be done on a separate programming track, unless only one digital loco-
motive or one turnout decoder is connected to the Z21 via the tracks or other wiring or the
multi
MAUS
is set to “POM” mode. If programming is carried out on the normal track and there
is more than one digital locomotive on the track (or also other turnout decoders than ROCO
items 42624 and 10775), a programming command changes the settings of all decoders in the
system. So, for instance, you could accidentally program all decoders to the same locomotive
address.
3.2.1.
“CHANGE CV”
Here you can read CVs (see above) or add new values. The fi rst image of the display shows
the term “CV” and a fl ashing insertion marker. You can now enter the number of the desired CV
using the function buttons.
•
Confi rm with the Light / OK button. The displayed value is read out and displayed by the
decoder. If you only want to read out, exit the menu item using STOP.
•
Now enter the new value and confi rm with the Light / OK button. The display briefl y jumps
to “PROG” before you return to the initial “CHANGE CV” level.
3.2.2.
“LONG ADDRESS”
Only locomotive addresses from 1–99 can be stored in CV1. All locomotive addresses from 100
must be programmed with this menu item. To do this, it is necessary to enable “long addresses”
in the locomotive decoder using CV29 (follow the decoder instructions!).
When you call up this menu item, “CV 17 / 18
” is briefl y displayed. The display then immediately
jumps to the address stored for the last locomotive used – with “L” in front and fl ashing value.
You can now enter the desired address using the function buttons. The digit(s) of the displayed
value disappears when the fi rst digit is entered.
•
Confi rm with the Light / OK button. The display briefl y jumps to “PROG” before you return to
the initial “LONG ADDRESS” level.
