1. Download a "KLD Profile Analysis Reference Tool" on the Internet (Note: you need to download the analysis tool corresponding to the year when the map version was released, such as the map of 20 12, so you naturally need to download the corresponding KLD Profile Analysis Reference Tool 20 12, otherwise you cannot analyze it).

2. Find the map folder NaviReFile of the original image, and click it to find that NaviConfig.dll is the satellite port equipment data of KAILID, which can only be read by the KLD configuration file parsing and reference tool.

3. Analysis method: drag the file directly into the KLD profile analysis reference tool, and you can see the port number and baud rate of the map version.

4. There is a simpler way to view it, that is, click the original NaviOne folder, find the TXT document text named PortConfig, and then click it to directly see the port number and baud rate of the device. This method is suitable for some machine maps, and many old maps still need to be analyzed and read by the above method.
