Take a photo of the sensor head (the sensor serial number should be visible), its tubes (the correspondence or discrepancy of the tubes length should be clearly visible), take a screenshot of the main screen of the sensor and the Settings menu page in the application and send these data to tech support. | Take a photo of the sensor head (the sensor serial number should be visible), its tubes (the correspondence or discrepancy of the tubes length should be clearly visible), take a screenshot of the main screen of the sensor and the Settings menu page in the application and send these data to tech support. | ||
== Connection losses, issues with coordinates, power supply issues == | |||
In case TD-Online goes offline for several days, it is necessary to check the messages the device sent before going offline or, if it has come back online, to check the messages sent from the black box. On Wialon platform such messages are marked with blue color. | |||
The dianostic parameters that need to be checked are: | |||
- '''SRN''' - in case it is higher than 30, there is an issue with the GPS connectivity; either the connection with satellites is poor in this area or there is an issue with the device's GPS module or its antenna | |||
- '''RSSI''' - Received Signal Strength Indicator - shows the quality of GSM signal reception; if the values you see are below 20 this means that either the local 2G/4G coverage is poor or there's an issue with the GSM modem or its antenna | |||
- '''msg_num''' - a cumulative counter of the messages sent; it can reset from time to time but if it happens too often then most likely there's an issue with the power supply the sensor is connected to | |||

=== Checking the device manually === | |||
If the TD-Online in question is offline for too long, it is necessary to check it manually. | |||
Once next to the vehicle: | |||
1) Before doing anything with the wiring, try and check if the device can be detected via Escort app (via Bluetooth) | |||
2) If it cannot be detected, there's something with: | |||
* a) the cable | |||
* b) the fuse | |||
* c) the device itself | |||
3) Try and connect the TD-Online to an alternative power supply of 12-24 V (using C200M2 RS485-USB converter is an option) and check if it can be detected via the app; if this works, run a continuity check on the cable and the fuse using a multimeter; replace either or both of them if they are damaged | |||
4) If the TD-Online is detected via the app, try and hard reset it; should it come back online on the platform, be sure to report that to the tech support team | |||
5) If the TD-Online is detected via the app but doesn't come back online on the platform no matter what you try, download the log from it and share the file with the tech support; the log file is saved in the same folder where you previously saved a tank calibraiton table; if you have never saved any tables before, be sure to create and save one (you need only a few lines in the table with whatever values) | |||
