Seemless Integration

Our ARINC 429 interface allows seemless connection of real aircraft parts to your flight simulator. Using the point-and-click Cereal Bytes Interface, OEM parts such as radio communication panels, transponders and more can be connected to Microsoft Flight Simulator (FSX), Prepar3d (P3D) or X-Plane in a matter of minutes.

I/O Breakout Board

This board contains an 8-port Ethernet jack, which breaks out the pins to 8 corresponding rows of screw connectors. This makes it easy to break out ARINC, discrete, and analog inputs on your remote and/or OEM modules, giving them plug-n-play convenience. This also provides very convenient access to pins that need to cross-talks between modules.


The Cereal Bytes ARINC 429 Interface is expected to debut this summer at the 2019 Flight Sim Expo. To receive product development and availability updates, please contact us at and we will add you to the distribution.
