ZLSN3003S is an embedded TTL level serial port to Ethernet module with RJ45 network port, which can realize the transparent transmission of TTL level serial port data and TCP/IP/UDP data, and realize the user's MCU to connect to the network through the serial port. ZLSN3003S is a multi-functional embedded Ethernet serial port data conversion module, which integrates the TCP/IP protocol stack, users can easily complete the network functions of embedded devices, save manpower, material resources and development time, and make the product go to market faster.

Different from the cable connection method of ZLSN3003, it is ZLSN3003S welded installation method of pin header. The use of a single row seat to solder directly to the user's PCB is more convenient than the ZLSN3003 screw hole installation, and compared with the ZLSN2003S, the user design workload is less due to the ZLSN3003S with a network port. ZLSN3003S is designed to provide the most convenient embedded networking module.

ZLSN3003S provides two types of modules: 5V power supply and 3.3V power supply, please connect the PIN pin VCC5 for 5V power supply, and connect another PIN pin VCC3 for 3.3V power supply. The suffix H is a high-speed module, and the L is a low-speed module. The difference between the two is that the high-speed module has a higher temperature, but it can support a higher baud rate. For the ordinary 9600 serial port baud rate, you can choose to ZLSN3003SL this model.

• In terms of data stability ZLSN2003S it can support bidirectional transmission of large data at a baud rate of 115200bps without losing a single byte. It can work all year round and around the clock. Supports industrial-grade temperature range.
• Support online network upgrade firmware program, users can get software upgrade tools and upgrade firmware from ZLAN, and can upgrade to the highest version by themselves.
• Using the configured ZLVircom tool, you can search for ZLSN2003 modules within the management area network (cross-segment search is supported), and on the Internet. All parameters of the module can be configured at the touch of a button. It is very convenient to configure and manage the equipment.
• It supports the DHCP function, which can dynamically obtain the IP assigned by the DHCP server in the LAN.
• DNS is supported, and the destination domain name is automatically resolved as the IP, and the destination IP can be a dynamic domain name.
• As a TCP server, it supports a powerful connection capability of 100 connections.
• As a TCP client, you can connect to eight destination servers. As a TCP client, you can automatically reconnect after a disconnection. Implicit heartbeat technology is supported to ensure recovery after the network cable is disconnected.
• Supports UDP, UDP, multicast and other functions.
• The data bit supports 5~9 bits, the check digit can be None, Odd, Even, Mark, Space five modes, supports CTS/RTS, DSR/DTR, XON/XOFF flow control, 1~2 stop bits.
• Examples of host computer development include: VC, VB, Delphi, C++Builder, Java, and C# routines. It can also provide a DLL library and the source code of the call method of the function library, which can be downloaded from the ZLAN website.
