You wouldn't, by chance, be using Siemens analyzers (OXYMAT/ULTRAMAT), would you? While I don't have any VIs for the AK protocol, I do have stuff written for the Siemens ELAN protocol. We use a bunch of OXYMAT 6 analyzers here and get status and measurement data via ELAN.
Hope this is useful - post back if you're interested and I'll arrange to post/email them.

Dave
