Chinese Siemens MPI Adapter

Hi: Has anyone ever bought one of those $25 Chinese MPI adapters from ebay for the Siemens 300/400? I have one and there are no set-up instructions. Is there anyone out there that has had success with these? Thanks! RB

Not bought one but I'm sure that's where Siemens probably get there "badged" ones from anyhoo so I'm sure it'll be fine.

Be interested to know how you get on with it. Let us know ;-)
