Hello, dear Andrey
Model 102-b is not directly integrated into the application, however, most likely, it can be used under a different type of device in the application, since there are a lot of copies of such a tracker.
You can try to choose Xexun TK102 device type
Also, you can try to identify your tracker on id.wialon.net as one of the Concox, Coban or Xexun devices.
If your tracker is determined, take a screenshot, write down the name of the model of the tracker and the identified ID (may coincide with the IMEI, may be part of it with zero or without).
After that, return to the application.
Then, knowing your device type and exact ID, create a unit on the system. – https://gps-trace.com/en/help/ruhavik/create-unit
After creation, you will get a IP and a port to which you want to direct the device.
Also, these IP and port can be found in the Сommon settings of the created unit.
Configure your device to this IP and port.
This way, when your device starts sending data to the system, you will see your tracker on the map.
If you have any problems or questions during the setup process, write to us at support@gps-trace.com, indicating the login, unit ID with a link to this forum topic, we will try to help.
