n Description of the relationship

1. The telecommunication signal connection between the product and the platform carrier is connected by low frequency data method.

2. The product has a built-in locator that can replace the conventional positioning terminal and antenna. As shown in the following figure:

3. In the mode of RF signal access, this product replaces the conventional active antenna. When  connecting to the RF interface of this product, please ensure that the interface of the access party does not provide more than 5V power supply to this product to avoid possible power conflict or   damage. As shown in the following diagram.

4. When using the usb to TTL tool to connect with the computer, do not plug and unplug the usb while powered to avoid damaging the serial port.
