The NDT series displays and its accessories were designed with consideration of their usage in simple applications with a single display, or in large-scale systems with several displays. The versatility of the solution allows creating a required final system by gradual extension, not just in terms of the number of connected displays, but also in terms of their control. Good readability in different light conditions is ensured by ability to adjust display brightness (day/night mode).

In the simplest setup, all that is required is a single display and one IR remote control. This setup is suitable for small churches, where the maximum direct distance between display and the operator does not exceed 20 m.

In larger churches and cathedrals, where the distance for controlling display is longer, it is possible to take advantage of wireless RF transmission by using a control mini display NDT 38/3 with RF module. Mini control display is controlled with an IR remote control, while ensuring a long data transmission via RF (see figures with possible connection diagrams in a leaflet). This solution simplifies and shortens installation of displays.

Displays can be also interconnected with a 2-wire communication line RS485, while any of displays is able to receive control commands from IR remote control. All other displays will show the same information automatically.
