SRI gas chromatographs ( GC )
and PeakSimple data systems
manufactured from 1995 through
2007 were equipped with serial
interfaces. A typical 9 pin serial
cable is shown at right.
GCs and PeakSimple data systems after 2007 were typically supplied with USB interfaces.
A USB cable is shown at right.
Many computers and
most laptops no longer
have serial jacks ( as of
2010 ), so it is necessary
to use a USB to serial
converter to operate the
serial type GCs and data
systems with USB only
computers.
Fortunately USB to serial converter products
are widely available and sell for
less than $20.
A typical USB 2.0 to serial converter made by Cables Unlimited
( part# USB2920 ) is shown at
right.
It is IMPORTANT that the USB
converter is labeled as USB 2.0
compliant since most of the earlier adapters ( USB 1.0 or 1.1 )
did not function properly

The USB to serial adapter will include a CD. Put the installation
CD in the CD drive and then plug
the adapter into a USB jack on the
computer.
Do not use the
extension cable
( if one is included with
your adapter ).
The extension
cable is unnecessary and
sometimes
causes problems.
The “ Found New hardware Wizard” will appear.

It is IMPORTANT to force the Wizard to look for the driver on the
CD, not search the internet, so
click on No, not this time.
The screen shown at right is
from Windows XP. If you are using Vista or Windows7, the
screens will be different. We
will not show detailed screen
shots to avoid confusion since
every operating system has
slightly different looking
screens.
Follow the Wizard until
Windows says the hardware has been installed.
Verify that the USB/Serial
adapter is correctly installed by navigating to
the Device Manger
screen in Windows.
( My computer, then right
click, then Properties,
then hardware, then Device manager ).
If the hardware installation is NOT correct you
will see a yellow warning sign next to
the USB/Serial Adapter icon.
If the installation was successful,
then you will see the USB/Serial port
listed under “PORTS” and the Comport number will be displayed. In the
screen at right Windows has decided
that Com4 is the number it has assigned to the USB/Serial adapter.

Now that you know what comport
number Windows has assigned to
the USB/Serial adapter, return to
PeakSimple and click the Edit/
Overall Screen.
Enter the correct board
type for your PeakSimple system. If you
have a serial port connection it will be either
the Model 203 single
channel serial or the
Model 202 four channel serial.
Enter the
number 4 in
this box.
Enter the Comport
number from the Device manager screen in
the box. In this case
you would enter the
number 4.
Don’t forget to click
File/SaveAll so PeakSimple will remember
the number you entered.
