ZLSN4000 is a versatile RS232 to Ethernet embedded networking module. The ZLSN4000 consists of a ZLSN4000 base plate and a ZLSN2000 core plate. It is characterized by the smaller size (43mm×53mm) among the RS232 to TCP/IP modules. It has flexible power supply mode: it supports 5V or 9V~24V voltage power supply, and supports serial port power supply, 2pin pin header power supply, network port power supply and other power supply modes.

The software features are the same as those of the ZLSN2000, please refer to theZLSN2000 User Manualfor the software features.

• 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 1200bps~460800bps (1M or 1.5M baud rate can be customized) 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.
