Wi-Fi Serial Server
Serial to WiFi: Serial to WiFi converters can wirelessly enable dumb RS232, RS422 or RS485 devices. They can be used in two different fundamental modes of operation: Ad-hoc mode: A pair of serial to WiFi converters are configured to directly address each other: What goes in one end comes out of the other much like a pair of radio modems. Serial media converters provide conversion between serial networks and other media. They can transparently convert RS-232 signals to RS-422/485 signals, as well as convert RS-422/485 to RS-232 signals without changing the PC's hardware or software. The serial media converter lets you easily build an industrial grade, long distance communication system with standard PC hardware.
