4
th

Byte 1 of present output current value
6
th

Byte 0 of present output voltage value
7
th
byte
Byte 1 of present output voltage
8
th
byte Byte 2 of present output voltage
Note:
Suppose you want to set the maximum current to 3.12 A. Since 1
represents 1 mA, 3.12 A translates to 3,120 in decimal. With 2 bytes in Hex, that
would be 0x0C30. Since the bytes are ordered in little-endian format, 0x30 would
be the 4
th
byte, and 0x0C as 5
th
byte.
