Serial RS232/RS485/RS422 to TCP/IP Ethernet Device Server If you are trying to connect a serial device that is not close to a local computer, here is a rugged powered serial to ethernet device server for you to remotely access, control, and manage serial port device over TCP/IP network easily, regardless of the distance between the server and client computer. Computer networking serial server supports RS-232 and RS-485 working Independently at the same time, e.g. RS232 and RS485, or RS232 and RS422. (can’t do RS422 and RS485 at the same time) Dual Serial port server is well constructed with compact and protective solid steel enclosure for tabletop, wall mount or DIN rail mounting Important: pls make sure the IP of computer and our device server is in the same network segment, so it can work. RS-232, RS-485/422 3 in 1 serial port to 10/100 Base self-adaptive Ethernet interface (compatible with 802.3 protocol) full duplex RS422 and half duplex RS485 data communication Built-in Ethernet media transport layer (MAC) and physical layer (PHY) Support IPV4, not for IPV6 Baud rate: 300 - 921600 bps Modbus Gateway: Bi-directional Modbus RTU to Modbus TCP TCP Server, UDP Server, TCP Client, UDP Client working modes DHCP (Dynamic Host Configuration Protocol) Automatically obtain IP address, Dynamic DNS domain name access Power Option: external power adapter AC to DC, or PoE (power over Ethernet, pin 4/5 and 7/8) Electrostatic protection ESD: ±5kV wide voltage input range 12V?70V, output 1000mA Appliances ATM terminals, Credit card and check verification system, Data collection, Gas pump, Industrial and medical remote monitoring system, Point-of-sale terminal, Remote diagnostic, Remote metering, Security system, Ticketing/Vending/gaming machine, ...
