Last Connection Date and Time
This menu is informational only, and tells you when the controller was contacted last.
Click on the “Submit” button to save the changes.
Connection Lifetime (PSTN or cell modem only)
This menu allows you to set a time limit on the Internet connection if no changes have been made. This
will help control the cost of operating the controller if you forget to log off. Type in the text box the
number of minutes that you want to pass by before disconnecting the Internet connection.
Entering a connection lifetime of “0” means the connection will never timeout.
Manual Internet Connection (PSTN or cell modem only)
Click on the Connect button to manually test the WebAlert’s ability to successfully connect to the ISP.
This is convenient on installation, or to troubleshoot Internet connection problems. The Connection
Status field will display what is happening as described above. Once you see that the Connection
Status is “On-line”, you may disconnect the controller from the Internet by clicking the Disconnect
button.
Signal Strength Test
Click the Start Test button. It will prompt you to verify that you really want to start the setup. Click Yes
and the test will begin. The controller will disconnect from the Internet and show the current signal
strength in the Last Known Signal Strength field below.
Click on End Test when you have finished. The dialup status should return to “Off Line.”
Signal Strength Test Suggestion
This field will tell you whether the signal strength is Good, or if its Bad and you should try to relocate
the antenna.
Last Known Signal Strength
This field will display the actual modem response string from the wireless modem. An rssi signal of 12-
36 is good, the higher the number the better. If it’s 12 then the signal is very marginal and you should
attempt to improve it. A signal of 99 is very poor.
Internet Connection Log (PSTN or cell modem only)
Click on the link to view the Internet Connection log file. You will be prompted to either open the file
(.csv format, normally opened in a spreadsheet) from its current location or to save the file to disk.
Make your selection. The file will display the date and time of all Internet connections, the type of
connection (ShoulderTap or Direct Modem) if the attempt was a success or a failure, and if it failed,
what the failure mode was.
VNet Log (VNet activations only)
Click on the link to view the VNet Connection log file. You will be prompted to either open the file
(.csv format, normally opened in a spreadsheet) from its current location or to save the file to disk.
Make your selection. The file will display the date and time of the VNet connections, if the attempt was
a success or a failure, and if it failed, what the failure mode was.
