Steuerungs-und Diagnosezubehör


The ERT interface provides an easy and convenient system to control and diagnose motorized monitors, microphone lifts and other automated solutions by Arthur Holm.
The ERT integrates 2 AHnet ports (RS-422) to control up to 60 motorized units (ERT-30 with 1 AHnet port to control up to 30 units) with a USB service port interface for firmware upgrade. The One Touch Addressing System [OTAS] makes the addressing of Arthur Holm motorized products to be straightforward. The first unit to be activated on the cover plate of the monitor after installation will have address No. 1, the next one will have address No. 2 and so on. [OTAS] is available on the majority of Arthur Holm motorized products.

The ERT interface helps to reduce the installation costs in terms of both equipments and time. It is easy to install and set-up. It enables a quicker installation and eliminates the need of external relay boxes and extra power outlets. It is also possible to have Arthur Holm’s virtual support on site as long as there is an Internet connection available.

AHlink wireless control is also integrated in the ERT interface, giving an easy and direct access to the most common settings through an app and making the start-up and future interventions hassle free. This means there is no need to access physically the unit to set-up or diagnose its installation.
