The iEFIS Extender is used mainly to add additional capabilities to an iEFIS Lite system.
It provides 8 analog/digital inputs, 5 digital outputs, OAT sensor input, 5 RS232 serial ports (for a total of 6 usable ports on the “Lite”) as well as a AOA (angle of attack) sensor
The Extender can also be used with regular iEFIS systems where it will provide additional analog/digital inputs and digital outputs.
Primary extenders should be connected on serial port 2 of iEFIS G3 and "classic" G4 Lite systems.
Primary extenders should be connected on serial port 4 of iEFIS "native" G4 Lite, MX2, and MX1 systems.
Secondary extenders for Lite, MX2, and MX1 systems can connect via CAN bus to add 8 analog or digital inputs and 4 digital outputs.
For extenders on Full systems with iBOX, use CAN bus 1. RS232 ports, CAN bus 2, OAT sensor and AOA sensor are not used.
