Feature

●【Host Slave Machines】: Slave does not need to respond to the host, it can only be used on a single slave device, and uses OxF8 as a universal address that can be used as a calibration address
●【Line Pin Pulses】: The new upgraded line pin pulse version is more suitable for integrated PCB use, which makes it easy to measure power and calibrate errors
●CRC Validation: Uses 16-bit format, which occupies 2 bytes, and produces a polynomial X16+X15+X2+1. The polynomial value used for calculation is 0xA001
●【Communication Interface】: The physical layer uses Vault 9600, 8 data bit, 1 stop bit, unverified, UART to TTL communication interface
●【Function Code】: Supports 0x03 (read hold registers), 0x04 (read input registers), 0x006 (write single register), 0x41 (calibration), 0x42 (power reset) and more. 0xF8 only)

How to use:
The TTL interface of this module is a passive interface and requires an external 5V power supply. This means all 4 ports must be connected during communication (5V, RX, TX, GND) Otherwise, the communication cannot be achieved.
