Even though the instrument is an offline DA-only instrument and you are not actually connecting to a live instrument, you still need to launch the setup wizard in order to create the instrument folder and its entry in the chemstation.ini file. After you click on the Configure Instrument option in the OpenLab Control Panel, you do not need to supply any information (like IP address or host name) in the configuration window. Just hit OK and then you will be able to launch an offline session of the DA-only instrument.
Great help, thank you very much!
