Failed to Connect to Instrument
This section describes the beginning-up of the LabOne User Interface which is used to command the SHFQA Instrument. If the LabOne software is not yet installed on the PC please follow the instructions in Software Installation. If the device is not yet connected please detect more information in Visibility and Connection.
The LabOne User Interface commencement-upwards link can exist found under the Windows 10 Starting time Menu (Nether Windows 7 and 8, the LabOne User Interface start-upwards link tin can be institute in Start Menu → all programs / all apps → Zurich Instruments LabOne). As shown in Effigy 2, click on Start Carte → Zurich Instruments LabOne. This will open the User Interface in a new tab in your default web browser and outset the LabOne Data Server and LabOne Web Server programs in the background. A detailed description of the software architecture is found in LabOne Software Architecture.
LabOne is an HTML5 browser-based program. This simply means that the user interface runs in a web browser and that a connectedness using a mobile device is also possible; only specify the IP address (and port 8006) of the PC running the user interface.
| By creating a shortcut to Google Chrome on your desktop with the Target |
After starting LabOne, the Device Connectedness dialog Effigy 3 is shown to select the device for the session. The term "session" is used for an active connection between the user interface and the device. Such a session is defined by device settings and user interface settings. Several sessions can exist started in parallel. The sessions run on a shared LabOne Spider web Server. A detailed description of the software compages tin can exist constitute in the LabOne Software Architecture.
Figure three. Device Connection dialog
The Device Connection dialog opens in the Basic view by default. In this view, all devices that are available for connection are represented by an icon with serial number and status information. If required, a push appears on the icon to perform a firmware upgrade. Otherwise, the device can be connected by a double click on the icon, or a click on the 
push button at the bottom right of the dialog.
In some cases it's useful to switch to the Advanced view of the Device Connexion dialog by clicking on the "Avant-garde" button. The Avant-garde view offers the possibility to select custom device and UI settings for the new session and gives further connectivity options that are particularly useful for multi-musical instrument setups.

The Advanced view consists of three parts:
-
Data Server Connectivity
-
Available Devices
-
Saved Settings
The Bachelor Devices tabular array has a display filter, ordinarily ready to Default Data Server, that is accessible by a drib-down menu in the header row of the table. When changing this to Local Data Servers, the Available Devices tabular array will evidence only connections via the Data Server on the host PC and will incorporate all instruments direct connected to the host PC via USB or to the local network via 1GbE. When using the All Data Servers filter, connections via Data Servers running on other PCs in the network besides become attainable. Once your musical instrument appears in the Bachelor Devices table, perform the following steps to start a new session:
-
Select an instrument in the Available Devices table.
-
Select a setting file in the Saved Settings list unless you would like to use the Default Settings.
-
First the session past clicking on
| By default, opening a new session will only load the UI settings (such equally plot ranges), merely non the device settings (such as bespeak amplitude) from the saved settings file. In order to include the device settings, enable the Include Device Settings checkbox. Note that this can touch on existing sessions since the device settings are shared betwixt them. |
| In case devices from other Zurich Instruments series (UHF, HF2, MF, HDAWG, PQSC, or SHF) are used in parallel, the listing in Available Devices department can contain those as well. |
The following sections describe the functionality of the Device Connection dialog in detail.
Data Server Connectivity
The Device Connexion dialog represents a Web Server. However, on get-go-upward the Web Server is not yet connected to a LabOne Information Server. With the Connect/Disconnect push button the connection to a Data Server can be opened and closed.
This functionality can usually be ignored when working with a single SHFQA Instrument and a single host figurer. Data Server Connectivity is important for users operating their instruments from a remote PC, i.eastward., from a PC different to the PC on which the Data Server is running or for users working with multiple instruments. The Data Server Connectivity function then gives the freedom to connect the Web Server to one of several accessible Data Servers. This includes Information Servers running on remote computers, and also Data Servers running on an MF Series instrument.
In order to piece of work with a UHF, HF2, HDAWG, PQSC, or SHF instrument remotely, keep as follows. On the calculator directly connected to the instrument (Computer one) open up a User Interface session and change the Connectivity setting in the Config tab to "From Everywhere". On the remote computer (Computer two), open the Device Connection dialog by starting up the LabOne User Interface and then go to the Advanced view by clicking on 
on the acme left of the dialog. Change the display filter from Default Data Server to All Information Servers by opening the drop-down bill of fare in the header row of the Available Devices table. This will brand the Musical instrument connected to Computer 1 visible in the list. Select the device and connect to the remote Data Server by clicking on 
. Then start the User Interface as described above.
| When using the filter "All Information Servers", take neat care to connect to the right instrument, especially in larger local networks. Always identify your musical instrument based on its serial number in the class DEV0000, which tin can be constitute on the instrument back panel. |
Bachelor Devices
The Available Devices table gives an overview of the visible devices. A device is ready for use if either marked free or continued. The get-go column of the list holds the Enable push controlling the connectedness betwixt the device and a Data Server. This button is greyed out until a Data Server is connected to the LabOne Spider web Server using the push. If a device is continued to a Data Server, no other Data Server running on another PC tin can access this device.
The 2d column indicates the serial number and the tertiary column shows the instrument type. The fourth column shows the host name of the LabOne Data Server controlling the device. The next column shows the interface type. For SHF Instruments the interfaces USB or 1GbE are available and are listed if physically connected. The LabOne Data Server will browse for the available devices and interfaces every second. If a device has merely been switched on or physically continued it may take up to 20 s before it becomes visible to the LabOne Data Server. If an interface is physically connected but not visible please read Visibility and Connection.
If a firmware update of the instrument is available, the second to final column volition prove a push button, and a elementary click on it will update the musical instrument. The concluding column indicates the condition of the device. Table 1 explains the significant of some of the possible device statuses.
| Connected | The device is connected to a LabOne Information Server, either on the same PC (indicated equally local) or on a remote PC (indicated by its IP accost). The user can start a session to piece of work with that device. |
| Free | The device is not in use by any LabOne Information Server and tin can exist continued past clicking the Open button. |
| In Use | The device is in use by a LabOne Data Server. As a issue the device cannot be accessed by the specified interface. To admission the device, a disconnect is needed. |
| Device FW upgrade required/bachelor | The firmware of the device is out of date. Delight commencement upgrade the firmware as described in Software Update. |
| Device not yet ready | The device is visible and starting up. |
Saved Settings
Settings files can contain both UI and device settings. UI settings control the structure of the LabOne User Interface, e.g. the position and ordering of opened tabs. Device settings specify the set-up of a device. The device settings persist on the device until the next power cycle or until overwritten past loading another settings file.
The columns are described in Table 2. The table rows can be sorted past clicking on the cavalcade header that should be sorted. The default sorting is by time. Therefore, the most contempo settings are found on top. Sorting by the favorite marking or setting file name may be useful as well.
| | Allows favorite settings files to be grouped together. Past activating the stars next to a settings file and clicking on the column heading, the chosen files will exist grouped together at the summit or lesser of the listing appropriately. The favorite marker is saved to the settings file. When the LabOne user interface is started adjacent time, the row will exist marked as favorite again. |
| Name | The name of the settings file. In the file system, the file name has the extension .xml. |
| Engagement | The date and fourth dimension the settings file was last written. |
| Comment | Allows a comment to be stored in the settings file. By clicking on the comment field a text can be typed in which is subsequently stored in the settings file. This annotate is useful to draw the specific conditions of a measurement. |
| Device Type | The instrument blazon with which this settings file was saved. |
Special Settings Files
Sure file names have the prefix "last_session_". Such files are created automatically by the LabOne Web Server when a session is terminated either explicitly by the user, or under critical error weather condition, and save the current UI and device settings. The prefix is prepended to the name of the most recently used settings file. This allows any unsaved changes to exist recovered upon starting a new session.
If a user loads such a last session settings file the "last_session_" prefix will be cutting away from the file proper name. Otherwise, there is a risk that an machine-relieve will overwrite a setting which was saved explicitly past the user.
The settings file with the name "Default Settings" contains the default UI settings. Run across button clarification in Table three.
| Open up | The settings contained in the selected settings file will be loaded. The button "Include Device Settings" controls whether merely UI settings are loaded, or if device settings are included. |
| Include Device Settings | Controls which part of the selected settings file is loaded upon clicking on Open up. If enabled, both the device and the UI settings are loaded. |
| Auto Start | Skips the session dialog at showtime-upward if selected device is available. The default UI settings will be loaded with unchanged device settings. |
| The user setting files are saved to an application-specific folder in the directory structure. The all-time manner to manage these files is using the File Manager tab. |
| The manufacturing plant default UI settings tin can be customized past saving a file with the name "default_ui" in the Config tab once the LabOne session has been started and the desired UI setup has been established. To apply mill defaults once more, the "default_ui" file must be removed from the user setting directory using the File Director tab. |
| Double clicking on a device row in the Available Devices table is a quick manner of starting the default LabOne UI. This action is equivalent to selecting the desired device and clicking the Open button. Double clicking on a row in the Saved Settings table is a quick manner of loading the LabOne UI with those UI settings and, depending on the "Include Device Settings" checkbox, device settings. This action is equivalent to selecting the desired settings file and clicking the Open push button. |
Tray Icon
When LabOne is started, a tray icon appears by default in the bottom right corner of the screen, as shown in the effigy below. Past correct-clicking on the icon, a new web server session can be opened quickly, or the LabOne Web and Data Servers tin can be stopped by clicking on Exit. Double-clicking the icon too opens a new web server session, which is useful when setting up a connection to multiple instruments, for example.

Letters
The LabOne Web Server volition show boosted messages in case of a missing component or a failure condition. These messages display information almost the failure condition. The post-obit paragraphs list these letters and give more data on the user actions needed to resolve the trouble.
Lost Connection to the LabOne Web Server
In this case the browser is no longer able to connect to the LabOne Spider web Server. This can happen if the Web Server and Data Server run on dissimilar PCs and a network connection is interrupted. As long every bit the Web Server is running and the session did not however time out, it is possible to just attach to the existing session and go along. Thus, within near 15 seconds it is possible with Retry to recover the old session connexion. The Reload button opens the Device Connexion dialog shown in Figure 3. The figure below shows an example of the Connectedness Lost dialog.
Figure 6. Dialog: Connection Lost
Reloading…
If a session fault cannot exist handled, the LabOne Web Server will restart to show a new Device Connection dialog equally shown in Figure 3. During the restart a window is displayed indicating that the LabOne User Interface will reload. If reloading does not happen the same effect tin be triggered past pressing F5 on the keyboard. The figure below shows an instance of this dialog.
Figure 7. Dialog: Reloading
No Device Discovered
An empty "Available Devices" table means that no devices were discovered. This can mean that no LabOne Data Server is running, or that it is running but failed to detect whatsoever devices. The device may be switched off or the interface connection fails. For more information on the interface between device and PC meet Visibility and Connection. The effigy below shows an case of this dialog.
Figure 8. No Device Discovered
No Device Bachelor
If all the devices in the "Available Devices" table are shown grayed, this indicates that they are either in employ by some other Data Server, or need a firmware upgrade. For firmware upgrade see Software Update. If all the devices are in use, access is non possible until a connection is relinquished past some other Data Server.
