The system devices can be split up in any way on each of the CAN buses.
The iBox features 2 CAN buses (CAN 1 and CAN 2). The CAN Connector (pigtail harness included with every iBox): The Outside Air Temp sensor also connects to the Power connector. It also has a Keep Alive Power input that maintains date and time and some non-volatile memory items without using the CR2032 battery, which can result in up to 10 years of life on the CR2032 eliminating the need to change this battery every year. The iBox can be powered by 1 or 2 Power Sources (as in the case of a backup battery system). The Power Connector (pigtail harness included with every iBox): The 2nd iBox acts as a ‘hot standby’ and is ready to take over all iBox tasks automatically when necessary, or on command by the pilot.Ĭlick on the DB-25 connectors above to see more information on those connectors. One iBox is necessary in every iEFIS system, and in cases where maximum redundancy is required, a 2nd iBox can be added to the system. The iBox is the hub of communication for all the system devices (AHRS, RDAC, Autopilot Servos) and is also the hub of communication with all third party devices (radios, transponders, ADS-B, VP-X) via its RS-232 and ARINC interfaces. Most importantly, Tellabs Optical LAN delivers ultimate security in conjunction inherently more secure fiber cabling, centralized.
It simplifies the design, build and operations of local area networks that continue to grow more complex. The iBox contains the GPS engine (with antenna connection), the pitot/static sensors and Angle of Attack sensors. Tellabs Optical LAN (OLAN) is a simple, scalable, stable and secure fiber-based enterprise network solution. Firmware Updates - Michigan Avionics The iBox is the heart of the iEFIS system, and the conductor in the symphony of communication between all system devices and the iEFIS screens.
