ZLSN3002 is a TTL level serial port to Ethernet module, its TTL level serial port is connected to the user's circuit board through the cable, so that the user can connect the original single-chip microcomputer serial port to the ZLSN3002 serial port without remaking the circuit board to realize networked data sending and receiving.

The ZLSN3002 is composed of 3002 base plate + ZLSN2002 module, and the user only needs to connect RXD, TXD, GND, VCC5V (the order of the lines is shown in the figure, from top to bottom: VCC5V, GND, TXD, RXD) to the user's PCB. The green LED of the network port indicates whether the network cable is well connected, and the yellow LED of the network port indicates whether the serial port has data transmission and reception. ZLSN3002 can be fixed through screw holes.

• Through the embedded web server, you can configure its network parameters, serial port parameters, login passwords, etc.
• The web server supports password login to prevent arbitrary modification.
• Cross-gateway support: It can connect the serial server to any host with a public IP address on the Internet.
• Support 1200~460800 baud rate.
• Support 9-bit data sending function: the 9th bit can be none, odd check, even check, 1, 0, five ways to distinguish data frames and address frames in 485 communication.
• The ZLVirCom configuration tool automatically finds a NETCOM device server on the network.
• Support virtual serial port.
• Data write protection is supported to prevent arbitrary tampering.
• Default configuration startup is supported.
• LINK pin connection indication.
• Hardware fluidic CTS/RTS.
• 1KV network surge protection.
