ZLAN8305/ZLAN8305L is a new cost-effective 4G DTU/ 4G router launched by Shanghai ZLAN. The differences between the two sub-models are as follows:

1) ZLAN 8305: support RS232/485 to 4G, do not support Ethernet port. Support serial port configuration.

2) ZLAN 8305L: supports 4G and Ethernet ports, RS232/485 to 4G/ Ethernet, and Ethernet to 4G. It can be used as a 4G router. Support serial port configuration, Web configuration, ZLVircom LAN configuration. Support the MQTT.

8305N2 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 8305N2 serial port by opening the virtual serial port.

8305N2 supports both P2P and N2N functions. The so-called P2P function, that is, when the user reads the data of the serial device through the 3G/4G network, there is no need to know the public IP address of 8305N2, no need to configure port mapping, and the zlvircom software of ZLAN can directly read the serial port data of the 8305N2. Similarly, the N2N feature allows users to read data from network devices connected to 8305N2's network port over 3G/4G networks without knowing the public IP address of 8305N2. All the user needs to configure is to enter the corresponding global unique number of 8305N2 into the zlvircom tool of the monitoring computer to find the device.

8305N2 supports Modbus TCP to RTU. Users can easily read data from RTU serial devices connected to the serial port of 8305N2 through Modbus TCP. The function of the Modbus gateway is an advanced storage Modbus gateway function, 8305N2 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.

8305N2 has multi-interface, P2P/N2N, Modbus and other functions, making 8305N2 a flagship product for remote device monitoring.

Select model: ZLAN8305 is divided into three sub-models: ZLAN8305 ZLAN8305L User Manual-5, ZLAN8305 ZLAN8305L User Manual-3, ZLAN8305 ZLAN8305L User Manual, all three models support P2P, N2N, Modbus functions. ZLAN8305 ZLAN8305L User Manual-5, -5 indicates 3G/4G models that support telecom, Unicom and mobile cards, including all functions of 8305N2. ZLAN8305 ZLAN8305L User Manual-3, -3 indicates that only the 3G model of Telecom is supported, including all the functions of 8305N2. ZLAN8305 ZLAN8305L User Manual, does not support 3G/4G, Wifi or Ethernet access networks.

ZLAN8305 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.
