You can use your laptop as a quick alternative together with a USB Optical Probe and a 3G dongle to read a meter in the case where the current communication is not working/non existent.
Download ActiveEtherpad.zip
You'll also need java on your PC
Extract it, right click on the extracted file active etherpad.bat and click Edit.
(notepad should open)
The file looks like this:
java -cp DetectMeter.jar SDG.Bridge 196.22.139.148:13234 ~ COM6
You'll have to change 13234 to the active etherpad port on adam
and COM6 to the com port that the optical probe connected on.
Save and close notepad.
Then you can run it, by double clicking active etherpad.bat
and if everything works, you should see a dos command window with:
connecting to 196.22.139.148:13234...connected
connecting to COM6...loading JavaCOM...done
connected

If you intend on always uploading the data for a specific site via this technique (laptop as etherpad); it would be preferable for you to add your etherpad on pnpscada as an "Always Connected Active Etherpad".
That way, pnpscada will always wait for your connection.
If you add it as just an "Active Etherpad", you will have to wait for the system to try to read your meter (which happens in half hour intervals); so you'll waste time whenever going to site.

Please make sure your data is up to date before leaving site, by logging into the system and checking that pnpscada did read the meter fully.
(Or use CaptureTotals to check what the last update date is, which should be today if it did update)
