Number Format
The number format used in AWS Client and QML logger configuration
changes depends on the number format selected in the Windows
regional settings.
You can change the Windows regional settings and the decimal symbol
using the Windows Control Panel. For instructions, please refer to the
Windows online help.
Opening Service Connection
Before you can download files or upload the setup file, you need to open
a service connection to the QML logger.
The supported connection types are serial port, TCP/IP socket, and dial-
up using a modem.
AWS Client supports any number of serial ports available in the
computer. The software reads from the registry of the Windows®
operating system which serial ports are installed.
This feature also enables the use of USB to RS-232 converter cables that
are usually installed above any other COM ports installed on a
computer. The COM port number of a converter cable depends on the
system configuration. For example, in a desktop computer with only
two physical COM ports (COM1 and COM2), a converter cable is
installed as COM3.
When reassigning the COM ports after installation, for example, when
changing COM5 to COM4 afterwards, you need to recreate the address
book entry for the modified COM port manually.
To establish a connection to the QML logger, select Connect from the
File menu. You can also click the Open connection icon. The Address
Book window is displayed as shown in
Figure 28 on page 58 .
CAUTION Using the incorrect decimal symbol when changing QML logger
parameters, for example, in sensor calibration or setting parameters,
may result in errors. Always use the decimal symbol defined in the
Windows regional settings.
