micro FIKO Data Exchange (uFDEX) is a serial protocol and data transfer system used as mini-LAN in vehicles and aviation systems. uFDEX uses embedded microcontroller technologies and may link into multiple RS-232, RS-422, RS-485 ports via one single antry point.

In todays world of communication, most people knows LAN systems used in PC's but few people knows that it's also possible to build small LAN systems that in fact are based on RS (Recommended Standard) protocols like RS-232 or RS-485 where RS-232 links between equipment are normally limited to 16 meters or 50 feet while RS-485 are limited to 1,200 meters or 4,000 feet. uFDEX may also link to BlueTooth, Wi-FI or VHF for wireless communication.

Because RS-232 is normally a point-to-point communication, uFDEX enables having several RS-232 connections to one and same RS-232 port by utilising a protocol structure via microcontroller to handle all I/O port data and in this way enables adding several RS-232 devices to one single port that may connect to i.e. embedded PC. This entry point can also be USB port by using USB to RS-232 converter.

As uFDEX is based on Star Network several branches of the star can be cascaded and in this way makes it possible to use different form of standards like one Star Network for RS-232, another for RS-485, one for BlueTooth another for Wi-FI and so on and at the end they can all connect to one single RS-232 or USB port making it the most flexible LAN system for i.e. vehicles, lab's, hospitals, home and office automation etc. that combines short, long and wireless communication into one single protocol structure that can also communicate with the CAN-bus used in vehicles.

uFDEX uses ID structure similar to what USB uses and each user must obtain such ID or use the prototype ID which is 270F in HEX or 9999 in DEC.
