Status packets
When you send a command that does not cause the power supply to send requested
information back to you, you will receive a status packet back. The structure of a status
packet is
Byte 0
0xAA
Byte 1
Address
Byte 2
0x12
Byte 3
Status byte
Byte 4 to 24
Reserved
Byte 25
Checksum
The meaning of the return status byte is defined below:
0x90
0xA0
0xB0
0xC0
0x80
Checksum incorrect
Parameter incorrect
Unrecognized command
Invalid command
Command was successful
