There really isn't one.
If you look up the Cisco d9865 you can find some from other sources which have at least the connection info.
The box has hdmi, component, composite, stereo and toslink optical out.
It has a network port , but it is not active/used.
The USB ports I beleive can be used for an extender but that's it.
There is an esata, which is primarily for the extender.
There are 2 USB ports on the back of my nextbox. Can I watch media from the USB when it's plugged into the box?
