Note: Experimental Aircraft Only The Aithre Shield EX 3.0-S is the first behind-the-panel device that puts carbon monoxide readings, pilot SPO2 from your Aithre Illyrian, and portable oxygen bottle PSI from your Aithre Altus Meso directly on EFIS using RS-232 output, as opposed to the voltage outputs of the sibling Shield EX 3.0. The EX 3.0-S works out-of-the-box with the current version of Advanced Flight Systems Avionics firmware. Check with your avionics manufacturer to verify support of the Aithre RS-232 protocol, which is published on our website on the Instructions & Resources page. Otherwise, see the sibling Shield EX 3.0 with its standard voltage outputs that are compatible with Garmin, Dynon, and other avionics manufacturers. Features simple wiring installation, a small lightweight footprint, iOS integration, and 10 years without recalibration for the CO ppm. Dimensions: 3X4X6
