6. Configuration

The Z21 signal DECODER can be configured in three different ways:
1. Via the programming button in configuration mode
2. Via the zLink interface using the Z21 per LINK (recommended method).
3. Via POM programming commands
In the interest of ongoing development, we reserve the right to improve and expand the settings and features.

6.1 Configuration via the programming button

If you do not have a Z21 per Link, the most important Z21 signal DECODER settings can also be set via the programming button in the
so-called configuration mode.
To access this configuration mode, the button must be pressed for at least 3 seconds until the white "Program" LED begins to flash.
Then release the button again.
The "Program" LED then displays the currently selected option:
Press and hold the button again for at least 3 seconds to accept the setting and jump to the next option. This is indicated by the blue
LED lighting up. After accepting the last option, configuration mode is exited and all settings are saved.
6.1.1 Option 1 – Program address
This option is used exclusively to program the first signal address and therefore also the internal decoder address.
1. Keep the programming button held down for at least 3 seconds until the white "Program" LED begins to flash. Then release
the programming button.
2. The white "Program" LED will then flash normally once (short, pause; short, pause; etc.), and the green LED will light up con-
tinuously. The signal decoder is then in "Configuration mode, Option 1".
3. Now switch a magnet accessory or signal of your choice. The magnet accessory or signal can be switched via the Z21
App or another input terminal, such as the multiMAUS. As soon as the switching command has been interpreted by the signal
decoder, the new address is applied and the configuration mode is exited automatically. The white LED goes out and the blue
LED indicates normal mode.
The addresses are programmed together for all signals, always in ascending groups of four. Each group of four consists of exactly four
consecutive turnout numbers, beginning with 1 to 4, 5 to 8, 9 to 12, 13 to 16 etc. The last programmable group of four ranges from
2037 to 2040.
