To retrieve sensor readings and interpret the values correctly on a រ៉ារីទីន PDU using the SNMP interface, you can follow these steps:
1. **Accessing Sensor Data:**
- Use SNMP commands like `snmpget` to retrieve sensor readings from the PDU. For example, to get the voltage reading of an inlet, you can use the command:
```
snmpget -v2c -c public -m+PDU2-MIB PDU2-MIB::measurementsInletSensorValue.1.1.rmsVoltage
```
- Replace `` with the actual IP address of your PDU.
2. **Interpreting Sensor Values:**
- **Decimal Digits:** Sensor readings are reported as integer values, but they may have fractional parts. Check the `DecimalDigits` column in the `SensorConfigurationTable` to determine the number of decimal digits. Divide the reading value by 10 to the power of the decimal digits to get the actual value.
- **Signed vs. Unsigned:** Determine if the integer value should be interpreted as signed or unsigned. Check the `Sensor-SignedMinimum` in the `SensorConfigurationTable` to see if the sensor can have negative values. Use `SensorSignedValue` or `SensorValue` accordingly.
3. ** ឧampលេ៖**
- If the `rmsVoltage` reading is `397` and the `DecimalDigits` is `0`, the actual voltage value is `397`.
- If the `rmsCurrent` reading is `1424`, `DecimalDigits` is `3`, and `SensorUnits` is `amp`, the actual current value is `1.424 Amps`.
By following these steps and referencing the SNMP commands and MIB structure provided in the ការណែនាំអ្នកប្រើប្រាស់, users can effectively retrieve sensor readings and interpret the values accurately on their Raritan PDU using the SNMP interface.
