This Article refers to the www.oemserver.com/Installer webpage

The Installer Page is not password protected - so installers without OEM/TG access can do a quick device check during/after an installation. Checking the following key indicators:

• Connectivity - Device Can Connect OK and is online
• GPS - is the device able to get a fix?
• External power wiring - it is powered correctly and reporting this to server. 
• Ignition/IO wiring - test if the ignition and digital inputs come on/off in response to changes in input - i.e. they're wired and configured properly.

Typical Installer Check Procedure

Enter your serial number (ensure it is correct) Does Last Communication and Last Commit say 'Now'? Only move onto step 3 if both answers are yes - as otherwise, the data following is out of date. Is the last GPS fix recent? To trigger a fix apply >5V to the white ignition line. Is Battery Level OK? (Internal LiPo batteries are 4.2V when fully charged, 3.7V when flat) Is External Power at expected level? Most devices need at least 9V reliably If you have a 12V supply, should be 12V etc Can you achieve both Ignition On & Off by toggling wire? This will require a refresh of the page to see change When the ignition is toggle to OFF - does the External power still remain at the right level? (This checks we haven't wired to a power source that shuts off when the ignition is off) Do any Digital Inputs (DI 1 etc) need to be activated? Toggle the inputs and check what is displayed on the installer (on or off) matches what is physically happening. If the behaviour is inverted (reads on when it should say off and vice versa) - this may potentially be a configuration issue which can easily be corrected server side by flipping the active level.
