OK ... had a go with that one.
It calls up the Welch Allyn Service Tool version 1.0.1.1.
I was able to get in just the once using the default User ID (whatever that was - see below) and <blank> for the password. But when I tried a second time, the User ID had er, disappeared. Bah! [but wait ... see below*]
If anyone else has a go (and be warned, it takes a while to download, and - possibly - a bit of fiddling about to install successfully), please make a note of that original User ID and let me know!
@Ed ... it looks like WAST 1.0 is for USB-equipped kit only. Make that Mini-B USB, in fact. And/or remote fault diagnosis and such
gee whizz stuff as that. Which is all very well when (if) it works, as we know! As we also know, the old 52000 has a 9-pin D-shell (male) serial connector. And I should imagine that the software mentioned in the 52000 manual is a bit more straightforward (older) than the one mentioned above (the one you linked to). Someone on here will have it,
inshallah.* A little later:- good news! It's ADMIN (see the
Manual)!
OK ... enough of this playing around ... a cup of tea, then back to work!
