The RealSimGear GNS530 is simply a control interface for X-Plane. This is made possible by the ArdSimX platform that is made available free of charge for non-commercial use. The ArdSimX software makes it possible to configure buttons, knobs, switches etc to perform certain functions in X-Plane.
A recent version of X-Plane also made it possible to 'pop out' the included Garmin 530 screen and position this on a secondary monitor. The virtual bezel for this display can be removed, enabling a near perfect representation of the actual Garmin 530 when paired with the RealSimGear hardware bezel.
The RealSimGear GNS530 consists of a custom designed printed circuit board (PCB) that has been fitted with switches for the various function buttons and two high quality dual encoders with their own push buttons for the radio frequency adjust and GPS page/chapter/cursor select. A 5" LCD screen connects to your PC via HDMI.
This is all packaged in a custom design bezel which replicates the real product. The bezel is molded in plastic and has been printed with labels.
