Introduction

Not all DCC System can programming or/and reading DCC:

Roco system: can programming decoders but can't read CV. Can't programming in PoM (Programming on Main) mode.
Lenz system SET-100 or SET-90: can both read and write CV. Can programming in PoM mode.
Before first read or write CV you must connect with DCC Systems.

Tab 'Parameters'

On this tab you should:

DCC System: select DCC System which will be used to programming.

Programming mode: select programming mode:
- Direct mode - most often used method
- Paged mode - older method used if previous failed
- PoM - newest method used without stopping trains (but can't read CV)

Engine - you can select one of defined engine or 'Other engine'. If you select one of defined engine than all reading and writing values will be remembered with engine. If you select 'Other engine' and PoM method then you must type in decoder address.
