DESCRIPTION
The ETH-SER-EE9 is a rugged industrial-grade power efficient (less than 1.4 Watts) serial device server which will convert from RS232, RS485 or RS422 serial to Ethernet or vice versa. The ETH-SER-EE9 serial device server will also make serial devices internet ready supporting TCP, UDP, ARP, ICMP, DHCP and Windows Native COM, LLF protocols. The ETH-SER-EE9 provides one serial port (RS232: DB9, RS485/RS422: 5 position terminal block) and one 10/100 Ethernet port in order to convert from serial devices to IP-based Ethernet and vice versa.
The ETH-SER-EE9 can be configured with a VSP Management Software and an online browser-based configuration tool or through AT commands. The software user interface is robust in functionality enabling the experienced Engineer to do complex configuration tasks while simple enough for a novice to use. All configurations can be performed by the Ethernet network (supporting communication across gateways and routers) or by the serial port, making the ETH-SER-EE9 convenient and user-friendly.
The ETH-SER-EE9 is designed with ESD protection as well as voltage surge protection and is specifically designed to function reliably in hazardous environments. It can be used as a stand-alone unit, wall or panel mounted or DIN rail mounted with optional DIN rail mounts. The unit is enclosed in a heavy duty steel housing for rugged applications. This converter operates 10/100 Ethernet and from 0 to 115,200 baud serial.
