Z21 interface configuration

This page describes how to configure a Z21 command station in Traintastic.

Tip

The Z21 can be added using the setup wizard, which guides you through the process step by step. See Quick start: Connect to your command station for details.

Supported connection types

Z21 command stations can only be connected to Traintastic over the network. All Z21 variants — z21 start, z21 white, and Z21 black — use the same configuration.

Connection settings

  • Hostname – IP address or hostname of the Z21 command station (e.g., 192.168.0.111).
  • Port – UDP port number. Default is 21105 and normally should not be changed.

Z21 settings

Additional options:

Debugging

  • Debug log RX/TX – Log all Z21 traffic (hex + description).
