I first trained on the IPX. I do remember that the IMX and IMS were different... I think I recall an IMS in the lab that split cables for 16-port cards, so some cards were shared across two cables...

Come to think of it, I think that the hex portion came in with certain commands... Georg, the instructor, liked to make it complicated... But it's now fairly easy for me to convert hex to binary, thanks to Georg...

Yeah, sorry, I read your post and thought it was a new thread. My bad.
