【Note】
Float (4Byte-ABCD) represents the single-precision floating point in the standard IEEE754 format, with a
total of 32 bits (4 bytes). Single-precision floating-point size end mode is ABCD (high byte first, low byte last);
String(14Byte-ASCII) represents a 14-byte ASCII-encoded string;
In configuration mode, the device is fixed to open 01H (and can also be accessed through 07E8H stored value)
address monitoring host request, using the fixed baud rate parameter 9600-8N1;
