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. The iBox contains the GPS engine (with antenna connection), the pitot/static sensors and Angle of Attack sensors. 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.

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 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.



Click on the DB-25 connectors above to see more information on those connectors.

The Power Connector (pigtail harness included with every iBox):
The iBox can be powered by 1 or 2 Power Sources (as in the case of a backup battery system). 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 Outside Air Temp sensor also connects to the Power connector.

The CAN Connector (pigtail harness included with every iBox):
The iBox features 2 CAN buses (CAN 1 and CAN 2). The system devices can be split up in any way on each of the CAN buses.

OAT Probe
Our aluminum OAT probe is included with every iBox

GPS Antenna
Our tuned GPS Antenna is included with every iBox (inside mount)

EFIS LAN coax
An RG-174 EFIS LAN coax cable is included with each system

Description

iEFIS MX1

Different from its iEFIS siblings, the iEFIS MX1 is  based on the latest developments in microcontroller technology. Microcontrollers have become very powerful indeed and are encroaching on the performance advantages of application processors. The MX1 is a manifestation of this. It packs most of the functionality of a traditional iEFIS system into a lower cost solution that requires fewer components resulting directly in potentially higher robustness and reliability in challenging environments.

The MX1 shines as a low cost single panel solution for many applications but can just as well be combined into an integrated multi-panel system with up to 8 panels very similar to a traditional, full function iEFIS system.

Simple installation and wiring up with built in, newly developed AHRS, altimeter to 40.000ft, dual airspeed sensors covering the range from just 20mph to mach 1 at sea level, built in AOA sensor, audio voice annunciation and sound generators for AOA and Vario, OAT sensor and built in WAAS GPS qualified to TSO-C199 SIL/SDA of 1/1. CAN bus and 4 internal RS232 ports (expandable to 8 ports). Support for all MGL devices and peripherals and several third party products. Analog and digital inputs and outputs with the iEFIS Expander.

Full iEFIS autopilot (up to three axis control), interfaces to transponders, COM and NAV radios as well as the MGL A16 intercom system.

Compatible with Custom User screens like previous iEFIS products

Operates in both portrait and landscape modes!
