hi all,

I am desperate. I have a chromatography system, dionex gp50 pump cd20 conductivity detector
the software i am using is the 6.60 chromeleon.

Everything was working fine, but lately there seems to be a failure of communication between the software and the pump/detector. The analysis is starting as it should be and after a point it stops and there is a message that says that
dx lan is timed out!!!!!!!! Sometimes because of a dx lan error i can not connect the pump or the detector.

Any ideas?

i have switched cables but nothing.

thank you in advance :?
