[cctalk] Anyone have any IO Corp 8219HP docs or info

Happy New Year everyone! I was wondering if anyone happens to have any documentation or information about the 8219HP adapter by IO Corporation? It is a protocol converter from Twinax to RS232 emulating an IBM 5219 printer. I am mostly looking for information about the option/rate switches on the back. I acquired one of these for cheap recently but haven't been able to find any information about it. Thanks!
