Clock synchronization is critical for Pluto hardware to operate correctly. If the system’s clock is incorrect, Pluto will not download data from the connected data loggers.
By default, Pluto hardware will connect to a public NTP server regularly for clock synchronization. However, if your organization does not permit access to public NTP servers, the new version of Pluto (SiteView-Web 1.4.96 or above) includes a feature that allows linking to a local SiteView server for clock synchronization.
Follow these steps to configure this feature:
1. Go to your local computer where SiteView was installed.
2. Make sure SiteView’s version is 4.4.9 or above and run it. Make sure to click ‘Allow access’ button when you see a dialog like this:
3. Click ‘NTP Server’ button under Others -> Tools menu:
4. In the pop-up dialog, check ‘NTP Server Enabled’ checkbox to enable it, then click ‘OK’ button to save the setting:
5. Reopen the dialog and notice the status shows ‘NTP Server is running’:
6. Visit Plut’s Admin Portal and browse to Admin -> Settings page from the top bar menu.
7. Scroll to the bottom of the settings page and click ‘Enable’ button for the ‘Custom NTP Server’ field:
8. In the pop-up dialog, enter the IP address of the computer where SiteView is running and click ‘Save’ button:
9. Notice the ‘Enabled’ field shows ‘Yes’ which indicates the system will link to the provided IP address for clock synchronization:
10. Go back to SiteView and notice new logs were added to the log sections indicating the remote Pluto is requesting clock info from SiteView’s NTP Server:
11. You may close this NTP Server dialog but need to keep SiteView running all the time.
This completes the settings for NTP Server.
