DCC-EX interface configuration

This page describes how to configure a DCC-EX command station in Traintastic.

Tip

The DCC-EX command stations 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

DCC-EX command stations can be connected to Traintastic in two ways:

  • Serial (RS-232/USB) – Direct cable connection, typically via USB or a USB-to-Serial adapter.
  • Network (TCP/IP) – Connection over Ethernet or Wi-Fi using the DCC-EX network protocol.

Connection settings

Depending on the connection type, the following options are available:

Serial connections

  • Device – Path to the serial device (e.g., COM3 on Windows or /dev/ttyUSB0 on Linux).
  • Baudrate – Communication speed, must match the DCC-EX configuration.

Network connections

  • Hostname – IP address or hostname of the DCC-EX.
  • Port – TCP port number, must match the DCC-EX configuration. (default: 2560)

DCC-EX settings

Additional options for fine-tuning behavior:

Locomotive control

  • Speed steps – Number of DCC speed steps to use for all locomotives.
    Options: 28 or 128 (default: 128).

Advanced

  • Startup delay – Delay (in milliseconds) between establishing the connection and sending the first command.
    Default: 2500 ms (2.5 seconds).

Debugging

  • Debug log RX/TX – Log all DCC-EX communication (ascii + description) for debugging purposes.
