There should be a USB cable, SD card and Log4.PoE device in the box. The Log4.PoE should be fully charged upon arrival.
Let the fun begin!
Turning device ON/OFF¶
- Short press START/STOP key Fig. 5 to start the Log4.PoE Device. The display will turn ON almost immediately.
- To turn off the device, press and hold the START/STOP key for around three seconds till the display turns blank.
Charging a battery¶
- Plug micro-USB to Monitor USB port of the Log4 Device, if battery is not fully charged, the CHARGE/READY light will be red. If battery is fully charged, the CHARGE/READY light will be green.
- Plug micro-USB to PC (or external power port)
It takes approximately 6 hours for the device to be fully charged.
Measuring Voltage, Current and power of an external device¶
- Connect PoE IN to a PoE enabled switch (PSE)
- Connect PoE OUT to the device that needs to be measure (for e.g. IP camera).
- Press START/STOP key to wake the Log4 Device if it is not already ON.
- Ta daaa! Current, voltage for each channel and power for channel A+B on the default screen (Fig. 52).
Connecting to Desktop Application (Log4 Analyser)¶
Live streaming of data can be achieved through the Log4 Analyser.
- Download the free Desktop application Log4 Analyser from Tektyte Website.
- Unzip and install application.
- Connect PoE IN to a PoE enabled switch (PSE).
- Connect PoE OUT to the device that needs to be measured.
- Connect Monitor USB to PC/Laptop.
- Open up Log4 Analyser.
- The device should connect automatically and start live streaming of data shortly (Fig. 53).
- The default sampling rate is set to be 10ms. If the Log4 Analyser is too slow or freezing, slow down the sampling rate on the device. See How to set Sample Period on LOG4.PoE.
- If the data does not stream immediately, USB cable may be faulty. Try with different USB cable.
- If the data still does not stream immediately, see Troubleshooting LOG4.PoE FAQ.
