/h = “1F40” in hexadecimal:
Sending of setting write command to RMEC: “01 10 04 58 00 02 04 1F 40 00 00 08 BD”
•
0x01: @RMEC
•
0x10: register write function code
•
0x0458: setting 1112 in hexadecimal
•
0x0002: Two 16-bit registers to read For reading of a 4-byte setting, specify a 32-bit register to
read, i.e. two 16-bit registers to read.
•
0x04: size of data to write (number of bytes)
•
0x1F40: LSB16 value in hexadecimal of the data “8,000m3/h”
•
0x0000: MSB16 value in hexadecimal of the data “8,000m3/h” The data is sent in LSB MSB format
on two 16-bit registers
