But the short answer is No, sorry... your plan is foiled
After knowing PT since it was SoundTools II 93' I am just learning the answers to this,,,, this week

Videos on OS9 w/ PT5 HD coming soon.
OS9 Lives will help you get into a PT system, were are you located?
Details....
on the back of the 192 & 96 is a DB60 port but it is a Thru / Out
to daisy chain 192i/o --> TO ---> legacy 888|24 , 882|20 , 1622
192 & 96 i/o can not directly connect and interface a Mix Core or Mix Farm card via the DB60 port.
192 & 96 can only be recognized in OS9 via ProTools 5.3.1 software thru a PCI-X HD Core card
in OS9 without PT5.3.1 the 192/96 are paperweight or a fancy door stop
the 192 is more of an investment than they appear
as they rarely come with digilink cables $40 - 80US used Sweetwater $70 - 130US
and DB25 to XLR or 1/4TSR snakes (you will need at least TWO) range from $50US on amazon to $450US on Sweetwwater
