Click on the downward arrow next to COM12, and you will get a drop down list of all in-use and available
ports as shown here:
If, for example, COM 1 is the only physical port installed and in use on the PC, move the USB Serial
Port to COM 2. This will be achieved by clicking on COM 2. Then click OK. If the port shows “(in use)”
as in this example, the following message will be displayed:
Click “Yes”, and then OK, then OK again. Finally, close the “Device Manager” and “Control Panel”.
The COM port used by the GS6000 Series analyzer will now be set to COM 2.
If multiple analyzers are to be connected simultaneously, then you will have to assign a COM port for
each. NOTE: You can only attach 8 analyzers (COM 1 through 8) simultaneously to the PC and operate
/ interrogate them with Systech Illinois Client.
7.4 Running the Systech Illinois Client Utility Software.

Series analyzer. Using the Device Manager in Windows, note which COM port is being used for the
USB connection.
