Connect to external DC Power Source:
IOT400 is designed with internal Battery Power source. It is suitable for the situation for not frequently data
logging or data uploading applications.
However, there is an alternative external DC Power Source for those applications required instantly or
frequently data uploading. Instead of battery power source, you can decide to apply external DC power source
to the IOT400 directly if there is available DC power source at the installation site.
