DS-7208HUHI-K2/P

Hi all you out thereThis is big ask
Does anyone have this hybrid dvr...... Hikvision DS-7208HUHI-K2/P using a Hikvision analogue ...DS-4225T-D9(C) rs-485 controlled camera? Or any other Hikvision PTZ analogue dome camera connected to this DVR?
Works absolutely fine by joystick locally, picture and ptz that is however will not ptz remotely,now if that wasnt enough I also have a chinese ptz turret analogue on the same DVR which works both locally and remotely with a superb picture!
Have tried all setting changes ,protocol,address,baud ,you name it, both on camera and dvr still cant get the Hikvision camera to move remotely, any and I repeat any ideas wheather considered trivial or not please feel very free to contact me!!!!!!

Thanks in anticipation
