TTL & Ethernet Bidirectional Transparent Transmission

This is a serial TTL to Ethernet module,used for data transparent transmission.USR-TCP232-T is a data transparent transmission equipment for converting TCP or UDP socket data to serial UART.

Product Features of  ethernet serial module

  • 10/100M auto detect interface;
  • support AUTO MDI/MDIX, Can use a crossover cable or parallel cable connection;
  • Work mode TCP Server, TCP Client, UDP, UDP Server;
  • Working model related parameters can be set via a serial port or network;
  • 3.3 V TTL level (module products);
  • Virtual serial port supported;
  • Unique heartbeat package mechanism to ensure that the connection is reliable, put an end to connect feign death;
  • Under UDP mode, Packet Broadcast is prohibited, with stronger anti-interference ability;
