: . : < - D < -Introduction: - The embedded D ( ) wireless data transmission terminal is a device specially used to transmit serial port data through a mobile data network. It is suitable for small and medium-sized centers with multiple points and scattered points. The amount of data transferred.
r:- Designed specifically for industrial integration. Special designs are adopted in terms of operating temperature range, vibration, electromagnetic compatibility and interface diversity to ensure stable operation in harsh environments.
r Based on r network development, data transmission has a wide communication range, stable transmission, and reliability - it has been widely used in fields such as unattended, remote equipment monitoring, remote data collection, remote meter reading, and remote dispatching.
r Targeted at < :r Applications in power system automation, industrial monitoring, traffic management, meteorology, environmental protection, pipe network monitoring, finance, securities and other industries
Taking into account the networking needs of each application department and supporting virtualization Data private network.
< - Features r # Standard industrial-grade product anti-interference design has strong adaptability to the environment
r # Embedded design has lower cost, power supply and easier user hardware integration development
r # Embedded d chip provided A variety of reset mechanisms can be /r: Software
Control to achieve a perfect industrial security mechanism
r #Support wireless remote upgrade, the D program can be upgraded through the server
r #The working frequency adopts/quad-band can Applicable to all countries around the world
r #Advanced and strict data communication protocol comes with error correction and encryption, and data transmission never loses packets
r #Powerful function supports three working modes: D (system default) D When in DD mode, it is r. The data transmission mode can send the serial port data (r/r or) of the user device to the server in the Internet. In D mode, it can also receive text messages (you need to switch to the port when sending text messages). In d working mode For the SMS transmission terminal mode, users can set the SMS transmission mode to type (with protocol) and type (transparent). The d mode is compatible with standard instructions (.). Users can complete the required functions by writing software with their own instruction set
r #Plug and play function: When networking with our company or yourself, you can build a large-scale D system without any software and hardware development
r #The automatic registration mechanism can realize the construction of multiple service models Complete ultra-large-scale wireless application system
r #Remote sleep and wake-up: You can use a designated mobile phone number to dial the D number to sleep and wake up the pair, which is convenient for users to put D to sleep when not in use, greatly saving traffic charges
r #Switching function: It has two switching inputs and two switching outputs. You can control the switch input or query the status of the switch input through the network or SMS. The alarm can be turned on remotely and the input alarm mode can be set: r alarm and alarm, and the alarm status threshold can be set (low-level alarm or high-level alarm). In addition, users can also customize the alarm information content
r #Powerful Communication backup function: If the backup service function is turned on, the connection between the main server and the backup server can be automatically switched. Once there is a problem with the main server, it will automatically connect to the backup server
r # Powerful server software supports server software applications for many years. Powerful and mature functions
