Introduction for RS232 to Ethernet Converter

USR-TCP232-302 is a low-cost solution to add networking connectivity into any device with RS-232(DB9) capability. By connecting USR-TCP232-302 to a RS-232 equipment, user can easily offer Ethernet networking capability as a standard feature. So equipment can be accessed and controlled over the Internet.

USR-TCP232-302 embedded serial device server is a highly integrated RS232 to Ethernet converter in small size. It includes standard TCP IP protocol stack, an embedded web server, 10/100Mbps TX Ethernet port and Magnetic isolation for hardware protection. This easy to use networking serial to TCPIP server enables engineers spend little time to add networking function to products. Simple configuration via a standard web browser or USR software makes it work.

The built-in web server support webpage modification. This RS232 to Ethernet converter have 6 KByte sending buffer of network, 4 KByte receive buffer of network and 2 KByte receive buffer of serial, which makes the communication more stable and safe.

Features of the RS232 to TCPIP Device Server

  • Transparent Transmission, do not need data parser
  • HTTP Client: send data as HTTP format automatically
  • Support DHCP client: automatically obtain an IP address and query IP address
  • DNS address can be modified
  • User Defined MAC address
  • Synchronous and adaptive serial port baud rate
  • Registration packet: identified header can be added to packets to check connection status
  • Heartbeat packet: can be sent to serial or network periodic. To ensure connection is reliable, end the dead link

Working Modes of the RS232 Serial Device Server

Serial Device Server TCP232-302 can work as TCP Client, TCP Server, UDP Client, UDP Server Mode.

1) In TCP Client Mode: Client connects Server automatically. User should configure the TCP Server’s IP address and Port.

2) In TCP Server Mode: The Max Client number can be modified from 1 to 16. By default, Client number is 4.

3) In UDP Client Mode: serial data will be sent to a fix IP address/port which you appointed.

4) In UDP Server Mode: serial data will be sent to last source IP/Port.
