As for software, I'm not sure if the various newer Encore products will work for your machine (I think they might)...
But in any case, if you'd like to obtain the EncoreBasic software, you can read how to do that here:
(you'll need to be logged into your forum account to access that link).
If EncoreBasic doesn't work, you can try EncorePro. It's a much, much larger and more complex software program and isn't as simple to use as EncoreBasic, however. But if you think you might need that one, send me a PM (Personal Message) and I can point you in the right direction on where to get it.
If anyone knows for sure whether EncoreBasic or EncorePro is compatible with the PR BiPAP AutoSV Advanced, please reply.
