The MGL iEFIS Challenger 10.4" is a color EFIS touch panel capable of operating as a "Full" iEFIS system when paired with an iBOX and sensors.
These are full feature systems and require an iBOX unit which is the central hub and sensor interface. AHRS, radios, engine monitors, and all other equipment connect to the iBOX and a simple coax connection is used for communication with the EFIS panel. Only power, iEFIS LAN coax, and video connections are available on the full iEFIS panels.
Up to 8 panels can be connected to 1 or 2 iBOX units and assigned priority (active vs passive panels). A second redundant iBOX is optional.
For iEFIS panels with some interfaces not requiring an iBOX unit, see our iEFIS G4 "Lite" offerings.
See Rob Holland's MGL panel showcased below. RIP RH
