LUN1793 is determined for displaying telemetric data. It is intended for installation on the instrument panel by means of DZUS fasteners. Small size determines it for installation in constrained areas. LUN1793 receives information from other systems (for example GPS) via RS 422 and ARINC 429 interfaces. In current configuration, this information is displayed on three following screens.

Furthermore this device is capable to process received data and send them to other systems (for example to computer with navigation SW running on). RS 422 serial output interface is intended to serve for these purposes.
There are two buttons on the front panel determined for switching between the screens as well as for entering the setting menu. There is possible to adjust display brightness for suitable visibility in this menu. The brightness is automatically controlled by level of environment lighting as well.
Typical application
LUN1793 is successfuly installed on MIG21/MIG29, TU154, L39/L59 aircrafts. It is directly connected to various sources of GPS data, namely to Bendix/King KLN900, Garmin 155XL, GNS400, GNS420, GNS430 and many others
