In addition to sensor selection, certain calculations depending on multiple
sensors need to be enabled and disabled separately.
NOTE If a sensor is removed from the AWS330 configuration according to table
Sensor Selection Parameters on page 149, any depending calculations
must be also removed by changing the corresponding selection
parameter, as described in Table 41 below.

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 which serial ports are installed from the
Windows registry1.
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 afterward, 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 89 on page 151.
