DSGW-091-1-US pinout serial USB?

Hi there! I have a DSGW-091-1-US product, and I want to connect to it via serial, but I can’t find any information about the hardware. I also can’t connect to the DSGW’s Wi-Fi. I tried using the MAC address (30:AE:7B:E8:7F:13) as the key to connect, but it doesn’t seem correct. I also tried 7BE87F13, but it was wrong as well. I can’t find any information about this in the documentation. Please help me!
