6.3.3 CV list

CV Description
#1 First decoder address, lower 6 bits (bits 0 - 5)
Together with CV #9, this generates the first decoder address for outputs 1 to 4.
This CV can only be read. You can change the decoder addresses via the programming
button. See section
veniently using the Z21 per LINK.
INFORMATION: Please ensure that the decoder address is never confused with the re-
sulting signal addresses. The signal addresses and CV values can be calculated from the
decoder address, but the process is rather complicated and is described in more detail in
the RailCommunity standards RCN-213 and RCN-225.
#7 Manufacturer firmware version number
#8 Manufacturer identification
Writing the value 8 resets all CVs to the factory settings.
#9 Decoder address, upper 3 bits (bits 6 - 8)
Together with CV #1, this generates the decoder address.
This CV can only be read. You can change the decoder addresses via the programming
button, see section
niently using the Z21 per LINK.
#28 RailCom configuration
®
Bit 1 = enable RailCom
INFORMATION: RailCom
#29 Decoder configuration
Bit 3 = RailCom
0 = Deactivated (decimal value 0)
1 = Activated (decimal value 8)
INFORMATION: RailCom
Bit 7 = actuation type:
1 = Actuation as accessory decoder
(decimal value 128, cannot be changed)
#39 DCC addressing mode
Assignment of the signal addresses to decoder address and output.
0 = backwards-compatible with ROCO control centres
Z21, multiZENTRALEpro and multiMAUS with booster
1 = DCC addressing mode conforms to RCN-213

TIP: This setting is recommended when using control centres from other manufacturers.
#40 Number of signals
Determines the number of signals which can be connected to the signal decoder. See also
section Light signals.
Factory setting: 2 signals
#41 Signal-ID for signal 1
When this CV is written, one of the predefined signal configurations is selected.
You can find more information on the available signal configurations in
gnal configurations.
Factory setting: Signal-ID 71 (0x47) "Universal"
