DTU
DTU is the abbreviation of Data Terminal Unit. Broadly speaking, when communicating, both ends of the link that transmits data. The module units responsible for sending data information are called DTU. Under its function, the format conversion and data collation and verification of the transmitted information are performed. In a narrow sense, DTU generally refers to the lower GPRS/CDMA/4G-LTE transmitting terminal equipment in wireless communications. The former is a module, while the latter is a device. The following introductions all refer to the latter (lower transmitting terminal equipment) unless otherwise specified.
The DTU developed by Zongheng Intelligent Control is different from other manufacturers on the market in that the product has many functions. At the same price and quality, Zongheng Intelligent Control’s DTU has more functions. At present, Zongheng Intelligent Control’s DTU has scheduled restart/timed triggering, supports active collection functions, supports JSON protocol, etc. It also has the function of a digital radio station and can be used for one-to-one networking or one-to-many networking.

DTU is also divided into many networks. As of 2020, the mainstream DTU is 4g DTU, Lora DTU, and nb-iot DTU. GPRS DTU and 3G DTU have been gradually phased out. With the emergence of CAT1 series modules, 4g dtu has gone from a price of more than 600 yuan per dtu to now being sold by most manufacturers for about 100 to 250 yuan.
It is a trend for 4G series DTU to become mainstream, because operators are focusing on operating 5G. The operating cost of 5G is high, and 4G is currently the most used, so 2G is destined to be eliminated.
Zongheng Intelligent Control’s 4g dtu
The functions of Zongheng Intelligent Control’s 4g dtu series products have been introduced above, so let’s introduce them below. There are currently three products that the company has developed, namely ZHC4013, ZHC401C, and ZHC4012, among which ZHC4013 and ZHC401C The communication module used is the CAT1 series module, so it is very cost-effective. The price is only 100~200 yuan per unit, and it provides 1-way RS485 interface. ZHC4012 is the original 4g dtu, which provides 1 channel RS232 and 1 channel RS485. The price will be more expensive. If you need an RS232 interface, you can consider this product. If you don’t strictly need an RS232 interface, it is recommended to buy the previous two models.
DTU has relatively few interfaces and functions. The RTU series products developed by Zongheng Intelligent Control have more functions and richer interfaces. If you are interested, you can click on the product display on this site to check it out!
