This product is aimed at applications in power system automation, industrial monitoring, traffic management, meteorology, environmental protection, pipe network monitoring, finance, securities and other industry sectors. Taking into account the networking needs of each application department, it is implemented on the network structure Virtual data private network. It is suitable for the transmission of small and medium-sized data amounts from the center to multiple points and dispersed points.
< .Product Features: Standard industrial grade product, anti-interference design, strong adaptability to the environment. Small size, low cost, convenient for users to use. Independent research and development, embedded bit R embedded chip with real-time operating system, provided A variety of reset mechanisms can be controlled by software to achieve a perfect industrial security mechanism. Advanced and strict data communication protocols, with built-in error correction and encryption. Data transmission never loses packets, the above pictures and animation files can be transmitted, and there will never be mosaic phenomenon. Multiple working modes:,, Three working modes are optional. When set to use, it is compatible with standard commands (. .), working In mode, users can set SMS transmission with or without protocol. It supports multiple data transmission protocols: regular, compatible, and transparent protocols are available. If used in conjunction with B, the user's previous software and equipment can be implemented without any changes, and the system's Internet-based applications can be realized. It supports multiple ways of automatic networking: it can be networked with the serial port network conversion product B, and B can also be of the same type as B. Product networking (convenient to use without Internet, can achieve one-to-one, one-to-many networking plug-and-play function: when networking with company B or B itself, no software or hardware development is required at this time. Constructing an automatic registration mechanism for large-scale systems can realize multiple service modes and build a complete ultra-large-scale wireless application system. Remote sleep and wake-up: You can use a mobile phone with a designated number to dial a number or send a text message to sleep and wake up, which is convenient for users when not in use. When it sleeps, it greatly saves traffic charges. Remote parameter modification: supports SMS parameter modification, and network parameter modification. Switching function: has two switching inputs and one switching output. It can be controlled and read remotely. Alarm status can be set threshold, and can set whether the alarm will automatically report an alarm signal. Powerful communication backup function: supports automatic switching of the connection between the main server and the backup server, supports automatic switching of communication. Once there is a problem with the main server, it will automatically connect to the backup server. If the connection fails, the server software with powerful communication function will be automatically used for support. The server software has been used for many years, has powerful functions, mature and perfect support for dedicated use. The data center supports fixed and dynamic domain name resolution. Industrial grade temperature range: Working temperature: ℃℃, at ℃ Communication is not affected.

Local parameters
R: The unique identifier of R, which plays a role in the communication process. Card number: the number of the card used, only for user records. Reconnection interval: if with the main server or backup server Connection error or disconnection, the time interval for reconnecting with the backup server or primary server. Local port: local or port heartbeat period: interval with server heartbeat, in seconds, range. Maximum packet length: send one packet of data. Maximum number of bytes (optional or bytes) Minimum packet interval: the minimum interval time of data packets () If the interval between two data received by the serial port is smaller than this value, it will be regarded as one packet, ~ The unit is the no-response reconnection period : If no response from the server is received for how long, it is considered that there is a problem with the network and the network should be reconnected. If set to , this item will not be checked. Range debugging output information: some working status information will be output during work, :does not output debugging information, outputs simple debugging information, :outputs detailed debugging information. When the user connects the device, it is recommended to set it to to avoid output information from interfering with the user's device. Device type: There are,, and three types. This parameter can be read but not set. When the user uses it, the user is prohibited from changing this parameter. Area code: the working area code to which it belongs. This parameter is generally not used. It may be used only when networking. Area code is valid: the work area code it belongs to enables or disables the central control number: the mobile phone number that controls sleep and wake-up and SMS parameter change. If this number is set, the number will be called. It can enter sleep or wake up after giving. Sleep mode can save data charges. If the number is empty, any call from any mobile phone number will cause it to sleep or wake up. Therefore, it is recommended that the user must set a number SMS control number: this number will only work when the work type is selected, and up to three numbers can be set. After setting this number, only the mobile phone with this number can send text messages to it, and no other numbers can send text messages to it. If all three numbers are set to empty, any mobile phone number can send text messages to it. Automatic alarm: When set to enabled, an alarm signal will be automatically sent to the server, otherwise no alarm signal will be reported. Threshold (foot): When automatic alarm is enabled When setting the status, high level is an alarm or low level is an alarm. The interface is the terminal B threshold (pin) from left to right: when the automatic alarm is enabled, set the status of B to be high level as an alarm or low level as an alarm. The maximum number of reconnections for the terminal of the interface from left to right: when it cannot connect to the server for how many consecutive times, it will restart. Parameters and server parameters
R's access point name. User name in China: the account name used to log in to R. When the user chooses a network, he must enter the username and password: Password for logging in to R. Main server: R. Address of the connected main server. Main server port: R. Port of the connected main server. Network protocol: R. Used by the connected main server. There are two user protocols: regular (), compatible), and transparent). Currently, all are regular () without special needs. Users are prohibited from changing the backup server: R The address of the backup server to be connected. Users can also set this value to the same backup server port as the primary server: R The port of the backup server that needs to be connected. Users can also set this value to be the same as the master server. Serial port parameters
Baud rate: The rate adopted by R's serial port, which can be selected from b Data bits: The data bits of R's serial port. Optional,,, four stop bits: the stop bits of R's serial port data, three options:,,., generally bit check: the verification method of R's serial port data, with or without checksum, even checksum , odd parity, r, etc. Flow control: whether serial port data transmission has flow control, whether there is flow control, hardware flow control, and software flow control are available. General users have no flow control. < .Application areas Water, electricity and gas remote automatic meter reading display screen information transmission water conservancy and meteorological data collection transmission machine networking power automation, distribution station change monitoring industrial instrumentation automation engineering chain or multinational unit equipment monitoring pipe network
