I am trying to get my 2690 working with a recently inherited PC containing Empower 2. I have been able to get Empower to recognize the equipment (2690 with 486 detector) and I can control the 2690 using Empower (i.e. turn on/off flow, change flow rate, change % composition, etc.) but when I try to run a sample using an instrument method, the 2690 turns on and the sample injects but the gradient does not run nor does the 2690 stop after the prescribed run time. It almost seems that the contents of the method never got communicated to the HPLC. Any help will be much appreciated; I would loathe to have to go back to my old Millenium setup...

twly
after the run time the 2690 keeps on going on the last known conditions until a new command is received from the empower. So that seems quite normal I would say.

About the gradient no beeing executed, don't know.
What function do you use in empower to start your analysis?
What about the data collection? Are the data being recorded or does the system just stays in a 'equilibrate' state?
if you program multiple injections, will they being executed or will it stay on the first one?

Maybe you can post your instrument meth, method set and sample set
