Magnatar Blu ray players

Has anyone tried to setup Magnatar UDP 800 or UDP 900 models?
It is kind of similar to REAVON UBR models
I tried using 8102 port ,
Device powers up with wake-up on lan but no further controls ….

I utilize an Oppo device that is compatible with Magnetar. It functions seamlessly with selecting Oppo 203. I connect it using Rs232 and adjust the baud rate as specified in the manual.

Thanks, I will try…
