E810-DTU(1RS1E) Ethernet to RS232/RS485/RS422

[Interface]:Ethernet to RS232/RS485/RS422


[Feature]:Transparent transmission

[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.

1Supply voltage
8V~36V,8V ~ 36V, more than 36V may burn, 12V or 24V power supply is recommended
