 Product Description

MX3220 serial device server (brief name: serial device server) is the independent development networking product of our company about RS-232/485/422 serial orifice terminal equipment.

The MX3220 series product adopts 32bit ARM MCU and combines efficiently embedded system and make equipment run more safe and stable

The MX3220 series serial device server none needs heavy investment to replace or upgrade.

It can let the original RS-232/485/422 serial industry control equipment immediately have a network to unite capability with each other, provide efficient, safe, stable data gateway for the serial orifice data information.

The MX3220 series product was applied to communication and control realm extensively, such as electric power supervision, engine room supervision, PLC, intelligence electric meter, gas meter and biological recognition device and reader...etc.,

It is the connectivity bridge between serial orifice equipment and TCP/IP Ether network.
