I-CON X.3 is a development from the previous version (I-CON X.2) which is an innovation in data communication. By using I-CON X.3, indicators that have serial pin out (RS-232) can be connected with various types of additional devices such as external displays, printers etc. Through radio frequency. The difference between I-CON X.3 and the previous version is the use of radio frequency as a communication medium. With this technology, indicators can connect with additional devices over long distances. I-CON X.3 is the right solution in terms of distance, for the needs of a wider range.
