The JL-20 series products of ETUNG Industrial Networking Terminal have passed internal and external testing and are starting to be mass-produced and shipped! The Industrial Networking Genie is a new series of products launched by ETUNG, reshaping the design concept of DTUs and routers as industrial communication transparent terminals in the past. It is compatible with DTUs‘ functions, and can also embed various protocols and connect with various cloud platform applications, making it easy to use and manage. The design of the Networking Genie product is more exquisite, convenient and intelligent to use.


JL-20 Industrial Networking Genie adopts an industrial grade design, providing remote data collection, transmission, and maintenance functions for industrial products such as controllers, collectors, industry data terminals, PLCs, and HIMs with serial ports. JL-20 has built-in MODBUS RTU communication protocol and can communicate with industrial cloud platforms through standard MQTT protocol; It also has built in NTRIP protocol as a communication device for high-precision positioning transmission, and connected to NTRIP Caster to achieve high-precision positioning function. We can also customize protocols for environmental protection, hydrology, electricity, and that can connect them to their dedicated platforms. The JL-20T Industrial Networking Genie is embedded with an industrial grade 4G LTE communication module, with one RS232 and one RS485 serial port each. It adopts terminal wiring and has a USB configuration port. Relying on ETUNG's E-Cloud Device Management Cloud Platform, JL-20T Industrial Networking Genie automatically obtains cloud device management capabilities, including device online and offline records, current online status, remote configuration, remote upgrade, remote debugging, etc.




There are two versions of the JL-20T series products: JL-20T Plus and JL-20T Pro. The specific parameters are shown in the following figure.
