The ZLSN2003S is an embedded module that connects Ethernet (TCP/IP) via a serial port (TTL level UART). It can do transparent conversion between serial port data and TCP/UDP data. It uses the newest generation of ZLAN1003 single-chip solution of Shanghai ZLAN, makes the product with “ultra-small” volume (16.3 × 19.1mm), and have a high degree of integration, with multiple functions: 100 TCP connections, DNS, DHCP, Web page custom download, and so on. It is the important epoch-making products of the serial to Ethernet network products to the miniaturization, integration of the demand.

ZLSN2003S internally operates ZLAN protocol stack with independent intellectual property rights, to ensure the stability of the operation of the product. In the hardware, it’s with industrial grade operating temperature range of minus 40 degrees to 85 degrees. ZLSN2003S internally has the remote network program installation function of ZLAN1003 chip, it can install a variety of customized applications on the firmware, to facilitate the realization of personalized design.

The high integration, convenient, cost-effective, stability of ZLSN2003S can allow the electronic systems easily realize network access.

ZLSN2003S uses double row pin structure. As long as connecting power, GND, serial transceiver, Ethernet port 4 lines, it can be used. Which Ethernet port 4 lines need to go through the network transformer or RJ45 with network transformer connecting to the external network cable.

Easy to integrate into the user acquisition, control system. So that the user's acquisition function system has the functions of network acquisition, network control. The specific approach is to connect ZLSN2003S TTL level serial port with the user's control panel MCU TTL serial port, to achieve data transmission network. As shown in Figure 3. Users can also purchase products with RJ45, model is ZLSN3003S.
