After GPRS DTU is powered on, first read the working parameters stored in the internal FLASH (including GPRS dialing parameters, serial port baud rate, data center IP address, etc., which have been configured in advance).

DTU is the full name of GPRS data transmission unit. At present, in China, there is actually a clearer agreement on GPRS DTU: GPRS DTU is a GPRS wireless device specially used to transmit serial data through the GPRS network. The following introduces the common problems of DTU application and the working engineering of GPRS DTU.

Managed switch or unmanaged switch: If the network structure is simple, you can choose a plug-and-play unmanaged switch; and if you take into account the convenience of subsequent maintenance and other factors, the managed switch is a better choice, because Only managed switches can achieve redundancy.

The industrial Ethernet switch adopts the storage conversion and exchange method, and at the same time improves the Ethernet communication speed, and the built-in intelligent alarm design monitors the network operation status, so that the reliable and stable operation of the Ethernet can be ensured in the harsh and dangerous industrial environment.

DTU is an abbreviation for Data Terminal Unit. Broadly speaking, when communicating, the module units responsible for sending data information at both ends of the data transmission link are called DTUs. Under its action, format conversion and data collation and verification are performed on the transmitted information.In a narrow sense, DTU generally refers to the lower GPRS/CDMA transmitting term···

wireless CPE is a terminal that directly converts broadband signals or mobile network data of 4G and 5G operators into Wi-Fi signals;

Simply put: AP is to convert a wired network to a wireless network, and CPE is to extend the distance of a wireless network.

CPE (Customer Premise Equipment), literally translated as Customer Premise Equipment, is actually a mobile signal access device that receives mobile signals and forwards them with wireless WIFI signals. CPE is a device that can convert high-speed 4G/5G
