Common Software Features
is section describes features common to all soware components.
1.1 On-Screen Keyboard
ere are times during RSWA usage when you need to type text: entering passwords, le
names, etc. Unfortunately, the RSWA unit does not have room for a built-in keyboard. In-
stead, when typing is necessary, you will see a virtual on-screen keyboard.
is keyboard allows typing using the touch screen.
Figure 1.1
Note: e layout of the keyboard depends on the currently active language.
To switch to numeric keypad and back, use button:

2RSWA Software Manual
is virtual keyboard is capable of supporting more than one keyboard layout in different
languages. To manage keyboard layouts, go to Control Panel → Regional and Language
Options → Languages.
1.2 Log In Prompt
When someone tries to run a protected Tessonics application they will get the log in prompt
shown in Figure 1.3. Only the users who have permission to access to the protected appli-
cation will be shown in the list. To log in, click your user name. If your user has a password
assigned, then you will be prompted to enter the password.
Figure 1.3 Login prompt
Each user has an associated icon to help them nd their name when logging in. It’s best
practice to assign each user a different icon. See the User Manager chapter in the RSWA
Administrator Manual for information on how to create and manage users.

Launcher
e Launcher allows the user to start Tessonics applications, and normally loads when the
RSWA starts up and replaces the Windows desktop. e Launcher was designed and built
for touchscreens, and is more convenient than a regular windows desktop. It also limits and
controls user access to critical system settings and programs.
2.1 Main Window
Figure 2.1 shows the main Launcher screen. For each application that is available, a button
is placed in the center (gray) section of the screen. Applications can be started by simply
pushing the corresponding button.
Figure 2.1 Main Launcher window
2.2 Logging In and Out
Certain Windows and Tessonics applications have been protected and require users to have
special privileges in order to use them. Some protected applications will allow you to log in
(for that application only) when you try to start them and others will not start at all unless
you are already logged in.

4RSWA Software Manual
Clicking the Log In button, shown in Figure 2.2, will bring up the Login prompt discussed
in Section 1.2, Log In Prompt. When you log in this way your user information is retained,
thus allowing you to start multiple protected applications without having to repeatedly log
in. is is the recommended way to use the RSWA.
Figure 2.2 Logging in and out of Launcher
Aer you log in, the label on top of the button shows the name of the current user. e
button caption changes to Log Out and now you can use it to log out of the system.
Note: If the computer goes to standby while you are logged in, the system will automati-
cally log you out to prevent unauthorized access by different users.
2.3 Turning Off
Clicking the Turn Off button will provide you with a list that allows you to Hibernate, Shut
Down, or Restart the computer; see Figure 2.3. Shutdown puts the system into off mode,
and Hibernate puts the system in Save-to-Disk mode. Restart simply reboots the system.

2.4 Switching Between Applications
When one or more applications are running the Switch button in Figure 2.4 becomes active.
Clicking this button provides a list of all the running applications and allows you select which
one you want to see or use. If an application is minimized this is the only way to bring it
back into view.
Figure 2.4 Switching between applications
2.5 Accessing a USB Drive
To access the USB port, open the aps on the right hand side of the so case. e location
of the USB port on the CPU unit is shown in Figure ??.
You can use any standard USB drive to transfer les to and from the unit.
When a USB drive is plugged in, the button in Figure 2.5 becomes visible. Clicking this
button provides the following options:
Figure 2.5 USB menu
Browse USB Drive
Opens Windows Explorer to work with les stored on the USB drive. is option is
available only to users with Admin permissions.
Safely Remove USB Drive
Select this option before unplugging the USB drive from the USB port.
Soware Updates
Selecting this option presents another list containing all the soware that can be
updated or installed from the USB drive. is option is only shown if there exists

some updates on the USB drive. See the RSWA Administrator’s Guide for more
information.
Warning: Always use the Safely Remove USB Drive option before unplugging the drive,
especially if you’ve modied les on it. Otherwise you risk loosing your data.
2.6 Launcher Tabs
e Launcher Tabs, shown in Figure 2.6, determine what is shown in the center (gray) sec-
tion of the Main Window, shown in Figure 2.1. e Applications, Utilities, and Admin tabs
show different groups of applications that can be started by the user; the Admin tab is re-
stricted to users with admin permissions. e Settings tab is also restricted to users with
admin permissions and it is discussed in Section 2.6.1, Settings Tab. e Info tab provides
some information about the RSWA and contact information for Tessonics.
Figure 2.6 Launcher tabs
2.6.1 Settings Tab
e Settings Tab is available only to users with Admin permissions. It contains the following
sections:
• Control Panel
• Launcher
• Applications
• Utilities
• Admin
• Deleted Items

Chapter 2 Launcher Launcher Tabs 7
Control Panel Section
Provides access to the standard Windows Control Panel.
Launcher Section
Allows you to choose which desktop application will be activated when Windows starts; the
Windows Desktop or the RSWA Launcher. Unless you have a good reason for doing so,
it is highly recommended that the RSWA Launcher be used. Using the Launcher limits a
user’s access to the computer and helps prevent them from accidentally causing soware
problems. e Launcher Section also allows you to set the default language that is used
with the Launcher and applications started from within the Launcher. e default language
selected in this section is completely independent of the default language used by Windows
and as a result will not have any affect if the Windows Desktop is used.

Array Explorer
is chapter explains how to use Array Explorer to analyze spot welds. It is important to note
upfront that the operation of Array Explorer depends on your permission level and whether
or not you are working on a inspection. Currently, Array Explorer has two permission lev-
els: standard and advanced. Some features are only available to advanced users, and some
critical settings can only be modied by the Admin user. ese features will be noted in the
explanations that follow. Inspections are explained in Section 3.10, Inspections, which are
the only way to save the RSWA’s measurements.
3.1 Main Window and Terminology
e Main window consists of seven areas, which are explained in the following sections:
