ZLAN8304N2 series can easily achieve remote access and monitoring of network port devices and serial port devices through 3G/4G/Wifi/ Ethernet, just like local access to network port devices and serial port devices. Zlan's P2P technology requires no port mapping or public IP address on the device, and is a recommended solution for remote monitoring and maintenance of network port and serial port devices.

8304N2 has 3G/4G functionality, and users can connect to 3G/4G networks after inserting a SIM card. Among them, ZLAN8304N2-3 only supports telecom networks, ZLAN8304N2-5 supports mobile, Unicom and telecom networks, and ZLAN8304N2 does not support 3G/4G networks, only supports Wifi/ Ethernet.

8304N2 series support 3G/4G router function, similar to ordinary 3G/4G router it provides 4 Ethernet ports can be connected to the Internet through 3G/4G network. Its Wifi support and 3G/4G/ Ethernet interface interwork can connect the Ethernet interface to the local Wifi AP access point, and can also be used as an AP access point for other laptops to connect to the 8304N2.

8304N2 provides two serial ports, each of which contains three types of interfaces RS232/485/422, which can be connected to various types of serial port devices. It has the function of serial port to network, the user's host computer can read the data of the serial port device through Ethernet, Wifi, 3G/4G and other interfaces through TCP/IP protocol. zlvircom software provided by ZLAN supports virtual serial port, and the serial port software of the upper computer can read the data of the serial port of 8304N2 by opening the virtual serial port.

8304N2 supports both P2P and N2N functions. The so-called P2P function, that is, when the user reads the data of the serial port device through the 3G/4G network, there is no need to know the public IP address of 8304N2, no need to configure port mapping, and the zlvircom software of ZLAN can directly read the serial port data of the 8304N2. Similarly, the N2N feature allows users to read data from network devices connected to the network port on 8304N2 over 3G/4G networks without knowing the public IP address of 8304N2. All the user needs to configure is to enter the corresponding global unique number of 8304N2 into the zlvircom tool of the monitoring computer to find the device.

8304N2 supports Modbus TCP to RTU. Users can easily read data from RTU serial devices connected to the serial port of 8304N2 through Modbus TCP. The function of the Modbus gateway is an advanced storage Modbus gateway function, 8304N2 can automatically remember the Modbus instructions to be read, can be dynamically updated and automatically accessed at any time, and put the read data into the local memory, which can greatly improve the data reading response speed on the network side.

8304N2 has multi-interface, P2P/N2N, Modbus and other functions, making 8304N2 a flagship product for remote device monitoring.

Select model: ZLAN8304 is divided into three sub-models: ZLAN8304N2-5, ZLAN8304N2-3, ZLAN8304N2, all three models support P2P, N2N, Modbus functions. ZLAN8304N2-5, -5 indicates 3G/4G models that support telecom, Unicom and mobile cards, including all functions of 8304N2. ZLAN8304N2-3, -3 indicates that only the 3G model of Telecom is supported, including all the functions of 8304N2. ZLAN8304N2, does not support 3G/4G, Wifi or Ethernet access networks.

ZLAN8304 series can be applied to:
1. Serial PLC, network port PLC remote program upgrade, monitoring;
2. Remote power meter, water meter reading;
3. Fire, security monitoring, at any time to view the status of remote equipment, real-time control;
4. Monitoring of field hydrological and meteorological data.
