It's 1290 Infinity II LC system. Now, the software shows that Sampler, Binary Pump, Column Comp., and DAD are all in Idle status.
However, I can not change any parameter for the binary pump (e.g. flow rate, mobile phases ratio...) or even change another method, and it says " Could not load method, because 'BinPump_1: Download Settings() failed!' Method may be partially loaded."
And then I turned off the power for Sampler, Binary Pump, Column Comp., and DAD, the software still shows Idle status.
Tried to restart the software, but it doesn't work.
It seems like the connection problem between the machines and software. Please kindly help to solve it.
