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/message/10363#10363
Come back if it that doesn't help either.
Thanks Alan for your guielines.
My Receives does not mention the brand or the manufacturer reference. the only thing I found Ref. URC32500-04R00 in the remote, which I checked in search engine and found out the receiver name is Pace brand Model TDC865COS, but in the list of slingbox the model shown is TDS865NV, which does not work.
The OSNBOX HD is a subscribe satellite receive from UAE and it comes with a prepaid card for activation.
I hope somebody may have a similar receiver and who knows the right configuration of the compatible model
