To check if the USB communication drivers have been properly installed on your computer, or to see if your
computer has an available serial communication port for a 9 pin serial cable, you will need to access the
Device
Manager
in your Windows operating system.

To access the
Device Manager
in
Windows XP
or

, click on
Start
, then right-click on the
My Computer
shortcut and select
Properties
. This will cause the
System Properties
window to appear. To open the
Device
Manager
, click on
Hardware
and then
Device Manager
.

To access the
Device Manager
in
Windows Vista
, click on
Start
, then right-click on the
Computer
shortcut
and select
Properties
. This will cause the
System
window to appear. To open the
Device Manager
, click on
Device Manager
.
From the
Device Manager
window, open the
Ports
icon to show which communication ports are currently installed
on your computer. In the case illustrated below, the computer has 3 installed communication ports which can be used
to interface with a TEC digital gauge.
–
COM1
and
COM2
are existing serial communication ports which can be used to communicate with a DG-700
gauge using a standard 9 pin serial cable.
–
COM3
is a custom communication port created by successfully installing the USB drivers for the DG-700
gauge. (Note: In order for a custom device communication port to be listed under the
Ports
icon, the DG-700
gauge must be connected to your computer.)
If no
COM
ports are listed (or a
Ports
icon does not exist), then either the computer does not have installed serial
communication ports, you have not properly installed the USB drivers to create a custom USB Device
communication port, or a DG-700 gauge is not connected to the computer.
