Abstract
ARINC 818 is defined as a point-to-point video link that is used to drive cockpit displays both in military and commercial aerospace applications. In addition to the ARINC 818 video link to a display, a command and control link such as MIL-STD-1553 is often needed to carry bezel button or other configuration and control data. Although ARINC 818 was envisioned as a video link, its high speed, low latency and high reliability make it ideal to carry both video and data. A bi-directional implementation of ARINC 818 provides ample bandwidth and messaging capability to eliminate the MIL-STD-1553 or ARINC 429 data interface with a single fiber or fiber pair. This paper examines the architecture and messaging structure required to include an ARINC 818 return path so that a separate data path is eliminated. A bi-directional ARINC 818 architecture is developed that maintains the 100% quality of service required for the video path and includes sufficient bandwidth to replace the low speed, copper data interface. Details are provided to on how to utilize networking capabilities inherent in ARINC 818 to easily enable bi-directional command and control.
