Hello, the setting is a little bit tricky. First, you must enable the legacy mode to do this you should download this app
https://www.machsystems.cz/support/1000BASE-T1 Pc App 20230321.zip.
In this app, you must connect to your media converter, and then in the section user switch select the legacy mode. Then click on write.
After that, you will be able to select the legacy mode with the last switch. The correct configuration is first switch off (auto-negotiation disabled), second off (slave mode), third on (speed 1000) and last on (legacy mode enabled). After that, you can connect the device to the car and the link LED should blink orange if everything is ok. Like in the image below.
Please tell me if this works.
