This RS-232 to RS-422/485 data extender with digital isolation can transform single-end RS232 signals to 4-way 2-wire RS-485 or 2-way 4-wire RS-422/485 form, and its industrial-class design can prevent it from surge, lightning strike and common-ground interface. C57 RS-485 can automatically control the data stream and monitor the rate, and transmission rate can reach 230kbps, which can ensure stable point-to-point or point-to-multi-point connections and realize the networking between some intelligent devices like PCs, PC and MCU, PLCs, etc.
