Hello Geoff,
The old Model of Medley communicates via the RS232 9 pint port situated on the back of the device.
Lol..First I thought IEEE 11073 was the answer to our ailing issues. Now another standard IEEE 1073? How many varieties of standard are we going to prod into?
I thought IHE would be helpful, but IEEE 11073 is a nightmare to understand and its like a jigsaw puzzle.

yes indeed protocol converters and parsers.

By the way which medical device manufacturer has decided to opt for IEEE 1073?

Cheers
Tim
