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. 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 (see chapter
3.3.
on page

). If programming is carried
out on the normal track and there is more than one digital locomotive on the track (or 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.
For programming on the separate programming track, either plug a track section electrically
isolated from the rest of the system to the track output of the Z21 or switch off the rest of the
track system with a switch before programming.
Note
: On the black Z21, the programming track output must be used (no reconnection
necessary).
Example
:
How to program locomotive address = CV1 to the value 4.
