Good day. Thank you for your question.
If you have installed the COM Port driver but are still not able to detect the device on the Configurator, please check the following:
1) LED behavior of the device - https://wiki.teltonika-gps.com/view/FMC125_LED_status;
2) any audible sounds from your PC/laptop (enable audio on PC/laptop) when the USB is connected to the laptop;
3) check the Device Manager on your PC/laptop if the USB is detected.
If the device is still not detected, please reach out to us via VIP Helpdesk or contact your Sales Manager/Distributor. If you don't have any contacts with our Sales managers, please contact them on our official website https://teltonika-gps.com/
and click on the "Contact Us" button. When you will click, please fill the form and submit it.
Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with the description of your situation to firstname.lastname@example.org
Thank you in advance.
