The Functions of serial to WiFi converter products are serial port to Wi-Fi, serial port to Ethernet, Ethernet to Wi-Fi, convert serial port data into TPC/IP network data, and achieve bidirectional data transmission. This article is to introduce the difference between USRIOT’s serial to WIFI converters.
Differences among series
Number of interface types: independent RS232 or 485, RJ45 interfaces
Wi-Fi band capacity: as the AP mode, it can carry different number of terminals
