RS-485 Command (MODBUS)

Command format：

a. Supports transmission speed：1200, 2400, 4800, 9600, 19200 (Default 4800)
b. Communication protocol: Modbus RTU
c. Function code: 0x03(read Hold Registers),0x10(write Multiple Register), 0x01 (read Coils),0x05 (write Single Coil).
d. MODBUS ID:0x10,default
e. The MODBUS protocol is required to be unlocked by the password (0x3C+0x3D(H):0x00 0x00 0x00, default) before using it. Or some of functions may not be able to be used.
