When the Systech Illinois Client Utility window is open, you should see the following box:
First select which port the analyzer is connected e.g. COM 1
Type in the correct command from the analyzer commands list (shown below) in the OUTPUT (to
instrument) window and hit return or click on “Send”. If communications are OK, then an answer is
shown in the REPLY (from instrument) field. Otherwise “TIMEOUT” is shown. This issue could be due
to an incorrect COM port selection, a disconnected or faulty USB cable or some other fault. Should a
“?1” be shown in the REPLY (from instrument) field, it means that the instrument does not understand
the question.
