The Nexus 10 is irrelevant. Any remote is stored in the Slingbox itself and used by ALL viewing systems.
If you are saying there is no remote when you setup the Slingbox on your PC/Mac, then I assume you have already done a proper Forum Search for your model number in case other people have already answered your question ?
If so and that didn't help then check out this thread: https://community.sling.com/thread/3300?tstart=0
Come back if it that doesn't help either.
