Hughes VSAT PES 5000 and 8000 systems

I have some old HNS PES 5000's and 8000's that I need to commission into a HNS Hub for testing purposes. I am able to get the remotes to lock to the hub outroute, but no dice with the inroutes back to the hub.
These systems are not supported any more by Hughes. I contacted Hughes training dept, and they were nice enough to send all the documentation on the HUB, but nothing on the the 5000 or 8000 remotes.

Does anybody have a copy of the old PES 5000 and/or 8000 manuals that they can email to me?
