The Aeroflex IFR Marconi T1200B is an ARINC 429 Control Display Unit engineered for real-time monitoring and control of avionics databus systems. It delivers dual low-speed and high-speed transceiver ports, enabling simultaneous transmission and reception across multiple ARINC 429 channels. The integrated 12.2-inch resistive touch-screen display provides intuitive operator control and system visibility. Purpose-built for avionics integration testing, the T1200B supports rapid prototyping, certification, and validation workflows across navigation, communication, and flight management systems.
