EC900 Series Operation Manual
V4.7
Expand out the "Ports" section and you will see an entry for "USB Serial Port" this is the 900 Series
analyzer. You will note that in the illustration above it has been installed as Com12. This is not
suitable for Systech_Illinois_Client as it is above Com6.
To change this Port number, Double click on "USB Serial Port", you should be presented with the
following screen.
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.
In this instance I know that Com1 is the only physical port installed and in use on the test PC. I will
move the USB Serial Port to Com2; this will be achieved by clicking on the list above on Com2. Then
Click on OK. You should (if the port is in use) get the following message.
