This may be the wrong forum as it's a Chromeleon connection issue but involves a Agilent 1100/1200 mixed module system.
When trying to connect one of our Agilent system to Chromeleon only the 1100 VWD will be detected if there is no instant pilot connected to the stack. As soon as an instant pilot is connected all modules get detected by Chromeleon. I am confident in our processes when getting systems connected as we have around 40 other Agilent systems set up without having the same issue and have had this system configured without issue before but I cannot locate any cause for our recent problem. I am also not aware of any significant changes being made to the Chromeleon instrument configuration or the physical stack that may have caused this issue to begin either.
I was wondering whether anyone else has experienced a similar issue.
