the power supply is in calibration mode.

The higher byte of voltage upper limit
The highest byte of voltage upper limit

Check sum
Note: Suppose you want to set the maximum voltage to 16.23 V. Since 1
represents 1mV, therefore 16.23 V translates to 16,230 in decimal. With 4 bytes in
Hex, that would be 0x0003F66. Since the bytes are ordered in little-endian format,
0x66 would be the 3 rd byte, 0x3F the 4 th byte, 0x00 as 5 th byte, and 0x00 as the 6 th
byte.
