The Z21 is a ROCO and Fleischmann innovation.
6.3.2 Conguration via POM programming commands for loco decoders
Most control devices, such as the multiMAUS, only provide POM programming commands for loco decoders. So that the Z21 signal
DECODER can also be congured using these types of control devices, the following option is available here: In the so-called “Con-
guration mode” (and only then!) the Z21 signal DECODER will, as an exception, also respond to POM programming commands for
loco decoders if these are directed to the “loco address” 9837.
TIP: Memory aid: Article number 10837  Pseudo “loco address” 9837
The conguration mode can only be activated via the Programming button on the Z21 signal DECODER. This excludes the risk of the
signal decoder being incorrectly adjusted accidentally, if in future an actual loco should be programmed to that address via POM. (On
the other hand, if a loco is to be assigned precisely this address, but you want to program the signal decoder, then please remove this
loco temporarily from the track if necessary, until you have nished conguring the signal decoder. This will ensure that nothing can
go wrong.)
To then congure the Z21 signal DECODER using POM programming commands for loco decoders as well, proceed as follows.
1. Put the Z21 signal DECODER in conguration mode by holding down the programming button for at least 3 seconds until
the white “Program” LED begins ashing. Release the programming button again. The white “Program” LED will then ash
regularly for a brief time. The signal decoder is then in “Conguration mode”. Incidentally, it does not matter for the POM
programming whether option 1, 2 or 3 is active.
2. You can now congure the signal decoder by using a WLANMAUS, multiMAUS or another input device of your choice to write
a CV variable via POM on the pseudo “loco address” 9837.
TIP: For multiMAUS and WLANMAUS, rst select the loco address 9837 before the POM programming, as well as the POM
programming mode:
If applicable: SHIFT+MENU  LOCO  MODE  ADDRESS  OK  STOP
SHIFT+OK  numbers 9 8 3 7  OK
SHIFT+MENU  PROGRAMMING  MODE  POM  OK  STOP
TIP: In the current Z21 APP (2020), you can nd the POM programming for loco decoder under “CV programming”  “Man-
ual”  “Program On Main”.
3. As soon as the POM write command has been interpreted by the signal decoder on a valid CV, the new value is applied and the
conguration mode is exited automatically. The white LED goes out and the blue LED indicates normal mode.
