User manual:
To get the most out of your Z21 system, please carefully
read the safety instructions and the user manual before
starting up the device.
We are continually improving and expanding our products.
A printed manual would therefore quickly become obsolete
and would then be an unnecessary burden on the environ-
ment. www.z21.eu/en/products/z21-signal-decoder

Quick guide
The Z21 signal DECODER is a universal DCC decoder for 2 to 4 complex light signals with a common plus. Depending on the
complexity of the light signals used, 2 to 4 different signals can be connected flexibly.
• 2 signals: 8 outputs can be used per signal.
• 3 signals: 1 signal with 8 outputs can be used. Two additional signals with 4 outputs can be used additionally.
• 4 signals: 4 outputs can be used per signal.
In addition to an all-purpose default configuration, numerous other predefined signal configurations from different countries
are available in the Z21 signal DECODER.
How to select those signal configurations and how to connect your signals, can be found in the manual at www.z21.eu/en/
products/z21-signal-decoder.
