Attached is the manual for the iEFIS Extender that can be used with the iEFIS (Discovery, Explorer and Challenger) and iEFIS Lite (Discovery-Lite, Explorer-Lite and Challenger-Lite) to add additional analog inputs and outputs as well as adding additional RS-232 serial ports. The available harness schematic is also attached.

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.
