Operation On Control Centres From Other Manufacturers - roco Z21 signal DECODER Bedienungsanleitung

5.3. Operation on control centres from other manufacturers

INFORMATION: When using control centres from other manufacturers, set the addressing mode of the Z21 signal DECODER
to "RCN-213"! To configure the addressing mode, see section
addressing mode.
The addressing mode defines the method used to calculate the turnout numbers from the accessory decoder address: Each DCC
accessory decoder address is assigned precisely 4 turnout numbers in accordance with the DCC standard. The 10837 Z21 signal DE-
CODER even assigns up to four consecutive accessory decoder addresses for the DCCbasic switching commands internally, depending
on the configuration (2,3,4 signals), and thus up to 4*4=16 turnout numbers.
Most user interfaces only display the turnout numbers and not the actual accessory decoder address. This accessory decoder address
is still only used in the background for communication between the DCC control centre and the signal decoder. For this to function
without problems, however, both sides, control centre and decoder, must use the same type of addressing mode. Unfortunately, due to
a weak spot in the older DCC specifications, different methods for calculating the turnout numbers from the accessory decoder address
have arisen over time. Only the RailCommunity standard RCN-213 ("DCC protocol operating commands for accessory decoders")
has defined since 2014 the calculation of the turnout numbers from the decoder address in an unique manner.
To be backwards-compatible with existing systems, as well as conformant with the RCN-213 standard, the Z21 signal DECODER offers
an adjustable addressing mode:
• Addressing mode "ROCO" for the purpose of backwards compatibility with Z21, multiZENTRALEpro and multiMAUS with boos-
ter. This is the factory setting.
TIP: Visual inspection on the 10837: The green "Data" LED is switched off in normal operation and only lights up briefly whilst
the signal decoder is receiving data or commands.
• Addressing mode "RCN-213" for the purpose of better compatibility with the current RCN-213 standard and with control centres
from other manufacturers.
TIP: Visual inspection on the 10837: The green "Data" LED is inverted, meaning that it remains switched on in normal opera-
tion, and only goes off briefly whilst the signal decoder is receiving data or commands.
TIP: This setting even functions with the Z21 if it has also been set to "RCN-213" in advance using the "Z21 Maintenance Tool"
(PC) or WLANMAUS.
The setting of the addressing mode relates primarily to ...
• ... switching commands: correct and consistent assignment of the signal addresses to the internal accessory decoder address.
• ... POM configuration commands: the POM programming commands only function correctly for accessory decoders with control
centres from other manufacturers when the "RCN-213" setting is used.
