## Summary description

The Kathrein ESU 56 is a robust grey metal unit designed for durability and performance. With its high-quality metal construction, it ensures long-lasting use in various environments. This model is ideal for professional applications, providing reliable functionality and ease of installation. Its sleek design not only enhances aesthetic appeal but also contributes to its overall efficiency.

## Long description

The Kathrein ESU 56 Grey Metal is a programmable single-cable outlet from the ESU 50 series designed to ensure interference-free reception in single-cable satellite systems. Its robust grey metal housing provides durable protection for the internal electronics while enabling convenient installation in professional and residential setups. The outlet contains a micro-controller that monitors signalling and enforces user ID checks so that only enabled user bands are forwarded from the end device to the multi-switch.
Advantages
The ESU 56 allows pre-programming of user bands and provides a controlled interface between end devices and the single-cable distribution. Configuration via the Kathrein ESU app together with the SWP 50 programming device lets installers lock or enable user bands and protect settings with a PIN. The unit’s metal construction offers mechanical stability and suitability for varied installation environments while the internal monitoring prevents cross-interference between outlets in multi-dwelling or multi-residence installations.
Suitable for
Single-cable (unicable/JESS) satellite systems in residential buildings
Multi-dwelling installations requiring controlled user band assignment
Professional installations where durable, metal-housed outlets are needed
Sites where interference prevention between outlets is critical
Key specifications

Series: ESU 50 programmable single-cable outlets

How to use

After programming, the outlet enforces user ID checks so that only the enabled bands are transmitted from the end device to the multi-switch, and other outlets remain unaffected by misconfigured or incompatible devices.
Usage recommendations
For reliable, interference-free operation across multiple residences, configure each ESU 56 with the Kathrein ESU app and protect outlet settings with a PIN; verify compatibility of end devices with single-cable systems before final commissioning.
