6.2 Conguration via POM
The Z21 switch DECODER can be congured for your applications on the main track via POMprogramming commands and CVs. “POM”
stands for “programming on the main” and “CV” stands for “conguration variable”, which are described in detail in the section CV
list. No programming track is required.
If the DCC control centre and the Z21 control centres have a RailCom
®
receiver, these CVs can not only be written to, but also read.
When using the Z21 Single or Dual BOOSTER (10806, 10807) and the CAN-Bus, POM reading is also possible in the booster section.
INFORMATION: Before POM programming with control centres from other manufacturers, set the turnout addressing of the
Z21 switch DECODER to “RCN-213”! To set the turnout addressing, see section Option 3 – Set addressing mode.
When programming on the main track, a distinction must be made between POM programming commands for accessory decoders and
for loco decoders.
6.2.1 Conguration via POM programming commands for accessory decoders
When using POM programming commands for accessory decoders, the Z21 switch DECODER can be congured using the Z21-Mainte-
nance Tool at any time even when installed.
