1210s not working with DVS and DJM750 MK2

Hi.

I have recently purchased 2 x XDJs Mk2, a DJM Mk2 and DVS licence and timecode to add to my 1210s.

I've installed the correct drivers and the XDJs are working via usb with a hub into my Mac (Mojave OS) although they are not picking up RekordBox only browsing via Midi Link.

However. Despite ensuring input is on correct channel in mixer on Rekordbox to photo on deck 1 and 4, and ensuring photo link is correct in settings, I am unable to get a signal from the timecode Vinyl. There's a signal to the mixer and analogue vinyl plays, but nothing to Rekordbox. I've tried all modes but am really struggling. 

Please Help!

Thanks
