Features:
1PCB Integration: The line pin pulse version is more suitable for the integrated use of the PCB of the power frequency communicating module, facilitating the measurement of power and calibration errors. 2Physics Layer Protocol: The physical layer of the voltage current meter TTL serial module uses a UART to TTL communicating interface. The baud rate is 9600, 8 data bits, 1 stop bit and no checksum. 3Application Layer Protocol: The application layer of the ammeter TTL serial module uses the RTU protocol for communicating. Currently, only 0x03 (read holding register), 0x04 (read input register), 0x006 (write single register), 0x41 (calibration), 0x42 (power reset) and other function code supported. 4Usage Scenario: The power frequency communicating module is used in situations such as factory calibration and return to the factory for maintenance. By default, the code with 16 digits added after the function code is 0x3721. 5Address Range of the Slave: The address range of the slave of the power frequency communicating module is 0x010xF7, and address 0x00 is used as the broadcast address. The slave does not need to reply to the master and uses address 0xF8 as a generic address. This address can only be used in the environment of a single slave device and can be used as a calibration address. 6CRC Check: The frequency communicating module's CRC check uses a 16-bit format that takes up two bytes and generates a polynomial of X16+X15+X2+1. The value of the polynomial used for the calculation is 0xA001. The value of the CRC checksum is the result of the checksum of all bytes of the data frame except for the CRC checksum value.
