ZLAN8308M is a new cost-effective guide CAT1 4G DTU from Shanghai ZLAN, and supports 2G GPRS mode. It can realize RS485 to 4G, CAT1 4G transmission speed up to 5Mbps upstream, 10Mbps downstream. It can realize RS485 data to 4G, using rail installation mode, easy installation. Compared with the traditional desktop 4G DTU, the width is reduced to about 1/4 of the original, and the size is small. The terminal type power supply is used, and the wide voltage input is 9 ~ 24V. The shell is made of high temperature, flame retardant alloy plastic, which meets the requirements of industrial site fire protection.

ZLAN8308MN adds P2P and M2M functions on the basis of 8308M, which can forward data through the cloud without the need for users to build their own servers. P2P is suitable for Intranet computers to monitor various serial devices through 4G, and M2M is suitable for communication between serial PLC and serial devices through 4G network.

ZLAN8308M not only has registered packets, heartbeat packets, but also has the newer MQTT, Modbus RTU to JSON docking cloud server and other functions, with high-speed transmission, low latency, support for new technologies and other features.

ZLAN8308M allows you to configure devices, upgrade firmware, configure MQTT/JSON and other advanced Settings through the serial port. It also supports centralized remote management of a large number of distributed devices through the server, and can remotely configure, remotely view status, and remotely upgrade programs. With the cooperation of public cloud or Zhuoran Cloud, it can realize Web-side device management and Web-side data viewing and remote control.

The collected data can be uploaded in JSON format for automatic data collection. Data acquisition support Modbus RTU, 645 instrument 97 version, 645 instrument 07 version, all kinds of non-standard RS485 protocols. ZLVircom can be used by users to configure uploaded data formats and JSON keywords. Upload can support MQTT protocol, HTTP POST protocol, HTTP GET protocol, transparent transport protocol, all kinds of non-standard network protocols.

Support edge computing functions, including: data overlimit alarm, data translation and scaling, data change upload, device offline alarm, device independent acquisition, device automatic connection and other functions. This feature is generally used in conjunction with the JSON feature.

ZLAN8308M has a specially designed watchdog circuit, which can ensure the stable operation of 4G modules for a long time. Products support the industrial temperature range of -40℃~85℃. Pass electromagnetic compatibility tests such as static electricity.

The ZLAN8308M is suitable for the following applications:
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.Field hydrological and meteorological data monitoring.
