Decoder Tester Extension, for LokSound XL V4 & L V4

Details:

The ESU Profi Decoder Tester Extension is an advanced expansion module designed to work in combination with the ESU Profi Decoder Tester (53900). It significantly extends the testing capabilities of the base unit, making it possible to evaluate large-scale decoders such as LokSound L and LokSound XL models in a controlled workshop environment.

When connected to the main tester, the extension provides dedicated multi-pin interfaces for direct plug-on installation of ESU large-scale decoders. This allows modellers and professionals to quickly test functionality without the need for locomotive installation, wiring or temporary setups.

A key feature of the extension is its 12-LED monitoring system, which provides real-time visual feedback for all physical function outputs. This makes it easy to verify lighting, auxiliary functions and switching behaviour at a glance during decoder diagnostics.

The module also includes additional connection points for a second speaker, sensor inputs and up to four servos, enabling comprehensive testing of both audio and motion control systems. For LokSound L decoders, dedicated connections are also provided for smoke generator testing, further expanding diagnostic capabilities.

By combining the extension with the base Profi Decoder Tester, users gain a complete professional-grade test bench suitable for almost all ESU decoder types.

The Profi Decoder Tester Extension is designed for advanced users, workshops and professional installers who regularly work with large-scale ESU decoders. It streamlines diagnostics by eliminating the need for locomotive installation, allowing rapid testing, configuration and fault-finding.

Its modular design ensures seamless integration with the base tester, creating a fully-featured test station capable of handling complex decoder functions including sound, lighting, servo control and auxiliary outputs.
