General Details

Introduction of Serial RS232 RS485 RS422 Ethernet converter

Serial RS232 RS485 RS422 Ethernet converter: USR-TCP232-306 is a multi serial port ethernet converter,which can realize bi-directional transparent transmission between RS232/RS485/RS422 and Ethernet. User can directly process data interaction through network and device to realize remote data acquisition, remote control and management.

Features of Serial RS232 RS485 RS422 Ethernet converter

  • Auto-MDI/MDIX, RJ45 port with 10/100Mbps
  • Work mode: TCP Server, TCP Client, UDP Client, UDP Server, HTTPD Client
  • Baud rate of serial port can be configured from 600 bps to 230.4 Kbps, supports check bit of none, odd, even, mark and space
  • Heartbeat package mechanism to ensure connection is reliable, put an end to dead link
  • User-defined registration package mechanism, check connection status and use as custom packet header
  • Supports RS232/RS485/RS422 port ( Can’t be used at one time)
  • Under TCP Server Mode, the connection number with client can be randomly set from 1 to 16, default number is 4. IP has been connected can be shown according to connectiong with calculating send / recceive dat.
  • When connection number reaches a maximun, the new connection is kicked off the old one can be configured by user
  • Parameters can be configured by built-in webpage, AT command, serial port procotol and network procotol. Setting procotol is avaliable to integrate into user’s software.
  • Supports TCP client short connection function, user-defined the disconnected time.
  • Device restart if no data transmission or timeout. User-defined the restart time.
  • If data buffer needs to clear configuration before TCP connection establishment
  • Supports DHCP, automatically obtain an IP address and query IP address via serial setting protocol.
  • The global unique MAC address, user-defined MAC address
  • DNS function
  • DNS server addres can be defined
  • Firmware can be upgraded by network
  • Provide Virtual com software
  • Restore factory setting through software or hardware
  • Running across the gateway, switches or routers.
  • Can work in LAN, also can work in the Internet
