Introduction  (RS232 to Ethernet Converter)
USR TCP232-302 is Serial RS232 to Ethernet TCP/IP Converter for bidirectional data transparent transmission. It is based on ARM processor and internally integrated with TCP/IP protocol.

Function (RS232 to Ethernet Converter)

  • Built in Web Server/Webpage for configuration.
  • User can modify the webpage.
  • 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.Can work in LAN, also can work in the Internet (external network)
  • Provide PC TCP/IP socket programming example such as VB,C++,Delphi,Android and IOS
  • 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, put an end to dead link.
  • The Max Client number can be modified, from 1 to 16.

Software
1) Parameter configuration software.
2) Virtual serial port software(VCOM), Windows 2000 or higher (32 bit/64 bit)
Factory Setting:
1) Hardware reset: Pull down Reload for 5 -15 seconds , then release it.
2) Software reset: Enter AT command mode, use AT command AT+RELD.
Firmware upgrade via network by Setup Software ( Manual P25)

Work Mode
Serial Device Server RS232 to TCP/IP Converter 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.
