[Introduction]:E810 (4RS1E) is a four serial port server of RS422 & RS485 & RS232 to Ethernet, which realizes transparent data transmission between RJ45 network port and RS422, RS485, RS232. The device is equipped with M3 series 32-bit processor, which runs fast and has high efficiency, with adaptive network rate. TCP Server, TCP Client, UDP Server, UDP Client four communication mechanisms.
