Serial Device Server Introduction

This is a serial RS232, RS485 or RS422 to Ethernet server, used for data transparent transmission. It is a low-cost serial device server, whose function is to realize bidirectional transparent transmission between RS232, RS485 or RS422 and Ethernet. USR-TCP232-306 is internally integrated with TCP/IP protocol. User can apply it to device networking communication.

Serial Device Server Feature

  • Can work in LAN, also across the Internet by gateway, switchws, router
  • Restore factory defaults by hardware and software
  • In TCP Server mode, max 16 TCP Clients can connect with it
  • Work mode: TCP Server, TCP Client, UDP Client, UDP Server
  • Heartbeat packet, ensure connection reliable, can be defined
  • Register packet, check connection status and use as custom packet header
  • Support firmware upgrade via network
  • Query IP address through serial setting protocol
  • Global unique MAC address bought from IEEE, user can define MAC address
  • Support virtual serial port and provide corresponding software USR-VCOM
  • Provide PC TCP/IP socket programming example such as VB,C++,Delphi,Android and IOS
