Internet function

1>The working mode can choose TCP Serve, TCP Client, UDP Client, UDP Server, Httpd Client.

2> The serial port baud rate can be set from 600bps to 256000Kbps.

3> Customize the heartbeat packet mechanism to ensure the authenticity and reliability of the connection and eliminate dead connections.

4> Customize the registration package mechanism to detect the connection status, and can also be used as a custom package header, and the MAC address can be used as the registration package. n

5>In TCP Server mode, the number of connected Clients can be set arbitrarily between 1 and 16, and the default is 4. The IPs of connected Clients can be displayed, and the data sent/received is calculated according to the connection.

6>In TCP Server mode, when the number of connections reaches the maximum value, it can be set whether the new connection kicks off the old connection.

7> Support TCP Client short connection function, short connection disconnection time customization. n

8> Support timeout restart (no data restart) function, restart time customization. n

9> Before the TCP connection is established, whether to clear the data cache can be set. n

10>DHCP function, can obtain IP automatically. n

11>The MAC address can be modified, the world's only MAC is programmed at the factory, and the custom MAC function is supported. n

12>DNS function, domain name resolution. n

13>DNS server address can be customized. n

14>Support bidirectional transparent transmission between serial port and Ethernet.

15>Support RS232, RS485 two kinds of serial port mutual transparent transmission.

16>Support (serial port) ModbusRTU to ModbusTCP (Ethernet)

Indicator Status Description

Power indicator light: red LED, it will stay on when the power supply is connected normally.

RS232 indicator light: Green LED, flashes when there is data transmission.

RS485 indicator light: Green LED, flashes when there is data transmission.

Network indicator: Green LED, fast flashing means connected to the network (about 1s), slow flashing (about 4s) means the network is not connected, and flashes when there is data transmission.
