RM520N-EU, RM520NEUDA-M20-8GASA; Sub-6/GNSS: 4+1(optional)::Manual?

I could not find the specification or a how to for the RM520N-EU that I have.
Can somebody help me with the pin connections and putting together the hardware?
My question is how to connect the antenna in/outputs there are 5: 0: ?, 1: ?, 2: ?, 3: ?, 4: ?.

Best way to connect with a 5G dongle that has four, (Quad,4) SMA antennas connected, with 4 IPEX cables.
Do I need a 5th antenna for GNSS? -Like e.g. a Molex 1558-1610MHZ GNSS FLEX ANTENNA?
Or make the GNSS disable pin on the USB TO M.2 B KEY active?

The RM505Q-AE device looks the same, however that would be an assumtion. Please let me known for the RM520N-EU.

Thanks in advance.
With best regards, Perry

Dear @Perry
Could you contact with your provider and get the hardware document? They have the corresponding ones.

Please, could somebody send me the pin configuration information for this device? Thanks!!!
