Command Information
Request Information
| Byte | Data Field |
|---|---|
| NetFn | 30h |
| CMD | 93h |
| 1:3 | Manufacturer ID, LS Byte first. The length is fixed to three bytes. For example, if the vendor ID is 2011 and the corresponding hexadecimal value is 0x0007DB, the first byte is DBh, the second byte is 07h, and the third byte is 00h. |
| 4 | Sub command, subcommand = 31h |
| 5 | Sensor type. For details, see Table 1. |
| 6 | Parameter Selector |
| 7 | Device #, 1 based, indicates the component number. The value 255 indicates the total power of a component (such as a CLU or fan) that supports total power query. Other values are specific component numbers. |
Response Information
| Byte | Data Field |
|---|---|
| 1 | Completion Code [0xC9] indicates that the entered part number exceeds the upper limit. |
| 2:4 | Manufacturer ID, LS Byte first. The length is fixed to three bytes. For example, if the vendor ID is 2011 and the corresponding hexadecimal value is 0x0007DB, the first byte is DBh, the second byte is 07h, and the third byte is 00h. |
| 5:8 | Reading, little endian, signed int type |
