E810-DTU(1RS1E) Ethernet to RS232/RS485/RS422,single serial port server,support TCP Server, TCP Client, UDP Server, UDP Client four communication mechanisms.

[Interface]:Ethernet to RS232/RS485/RS422

[Feature]:Transparent transmission


[Product weight]:130±5g

[Introduction]:E810-DTU (1RS1E) is a single serial port server that transfers RS232 & RS485 & RS422 to ethernet. It realizes data transparent transmission between RJ45 and RS232 or RS485 or RS422. Equipped with M3 series 32-bit processor, it runs fast and has high efficiency. With adaptive network rate (up to 100M full duplex), TCP Server, TCP Client, UDP Server, UDP Client four communication mechanisms.
