Created page with "==SBC Web Interface== Using the operating system sections of this guide, you should have been able to open a web browser with a connection to the SBC using either: * The Phid..."

New page

==SBC Web Interface==

Using the operating system sections of this guide, you should have been able to open a web browser with a connection to the SBC using either:
* The Phidget Control Panel (Windows), or
* The Phidget Preference Pane (Mac OS), or
* An mDNS connection (Linux).
Here we cover the basics on the tool that has been opened in the browser, known as the SBC Web Interface.

===Set the Password===

If this is your first time connecting to the SBC (or after a complete factory reset), you will see a screen asking you to set a password:

[[File:sbc_gs_set_passwd.png|link=|alt=]]

This password will be linked to the user {{Code|admin}} if you use the web interface in the future, and to the user {{Code|root}} if you choose to use SSH. These are actually the same user, and the SSH connection is covered in-depth on the [[OS - Phidget SBC|SBC operating system page]].

Remember this password, as you will need it to connect to the SBC in the future, and the only way to log in if you lose it is to perform a [[OS - Phidget SBC#Factory Reset|full factory reset]] on the SBC.

The next time you connect to the SBC after you log out or reboot the SBC, you will be asked to log in with a user name and password:

[[File:sbc_gs_login.png|link=|alt=]]

===Navigating===

The SBC Web Interface has a series of tabs and sub-tabs at the top, and by using these you can access the entire web interface. Note that the web interface only allows you to configure a very small portion of the SBC, please refer to the full [[OS - Phidget SBC]] page for an in-depth introduction on the SBC Linux operating system.

The header also has information about how long the SBC had been powered on without a reboot, what the link local address of the SBC is (here it is {{Code|phidgetsbc}}, so the full link local address is {{Code|phidgetsbc.local}}) and more:

[[File:sbc_gs_web_header.png|link=|alt=]]

The starting page of the web interface will also give you information about:
* The name of the SBC (you can rename it under {{Code|System → General}}, although note that this will '''also change the link local address of the SBC to that name''')
* The build, kernel, and board revision
* The MAC address (of the Ethernet connection...the wireless MAC address can be found on {{Code|Network → Status}} when the adapter is plugged in)
* The space left in your / filesystem (the amount of space you have for programs, and files not written to an external USB key)
* Any additionally mounted filesystems (such as a USB data key)
* The amount of memory your SBC is currently using. This can be a bit misleading however. To get a better idea of the total memory usage go to the "Processes" subtab and look at memory usage on a per-process basis.

This can also be accessed later from {{Code|Status → System}}:

[[File:sbc_gs_web_interface.png|link=|alt=]]

===Set up Networking===

After using the initial wired Ethernet connection (as described in detail in the [[#Hardware|hardware section]]) to access the web interface for the first time, you can use the {{Code|Network}} tab in the web interface to configure other network settings for use.

The SBC can switch dynamically between Ethernet (what it tries first) and wireless via the [{{SERVER}}/products.php?product_id=3702 Wi-Fi USB Adapter w/SMA Antenna]. It is also able to dynamically handle both Ethernet and wireless being unplugged and then plugged back in. This is especially useful if you are designing a project where the SBC will operate without a network - when testing you can plug in and remove the network adapters to check on how the SBC is doing.

====Wireless====

The SBC can only access wireless networks using the [{{SERVER}}/products.php?product_id=3072 Wi-Fi USB Adapter w/SMA Antenna]. If this WiFi adapter is plugged in to a USB port on the SBC, you will see something like this under {{Code|Network → Wireless}} in the web interface:

[[File:sbc_gs_wireless.png|link=|alt=]]

Here you can add and remember networks with passwords. These do not necessarily have to be networks that are currently seen - you can add the SSID and password of your home network, for example, and the next time the SBC boots at home with wireless only it will connect to your home wireless network. These SSID settings are only for DHCP networks.

====Static IP====

If you do not have DHCP on your main network, and do not want to use link local addressing, you can set the network connection to be static. These settings can be found in the web interface under {{Code|Network → Settings}} for the Ethernet interface, and at the bottom of {{Code|Network → Wireless}} for wireless networking. In the Ethernet settings, for example, you can specify network elements manually in the same way you would for a desktop computer:

[[File:sbc_gs_static_ip.png|link=|alt=]]

This setting is also useful to work entirely without mDNS and link local addressing. After setting it, the SBC will start using that static IP immediately, so if this is done improperly this can make the SBC very hard to re-connect to depending on the routing within the rest of your network. If you are not sure whether this will be a problem, it may help to read the in-depth [[OS - Phidget SBC#Initial Internet Setup|network troubleshooting section]] for the SBC.

===View Attached Phidgets===

You can view Phidgets that are directly attached to the SBC by going to {{Code|Phidgets → Status}} in the web interface:

[[File:sbc_attached_phidgets.png|link=|alt=]]

This will always show the attached Interface Kit that is part of the SBC board. It will also show any Phidgets plugged into the SBC's USB ports.

On the right hand side of this screen (not shown in the screenshot) you will see the serial numbers of the attached Phidgets. If you want to use these Phidgets within your code over a network using the webservice, you can use these serial numbers in your programming project.

Note that any analog or digital sensors will not show up here, as they are a 'part' of the Interface Kit and can be accessed through the ports in the Interface Kit API. Taking a look at the [[1018 User Guide|User Guide]] for the [{{SERVER}}/products.php?product_id=1018 PhidgetInterfaceKit 8/8/8] will show you a good example of how this works.

===Use the Webcam===

Using the webcam (either the [{{SERVER}}/products.php?product_id=3402 Phidget USB Webcam] or another [http://linux-uvc.berlios.de/#devices UVC-compatible webcam]) should be fairly straightforward. First, plug it in:

[[File:sbc_gs_webcam_hw.png|link=|alt=]]

Then, head to the web interface under {{Code|Webcam → Webcam}}:

[[File:sbc_gs_webcam.png|link=|alt=]]

This will allow you to stream video into the web interface. This stream can also be viewed with any compatible M-JPG viewer, such as VLC. To take pictures with the webcam within your code, see the [[OS - Phidget SBC#Taking Pictures with the Webcam|how-to]] on the main SBC operating system page.

Webcams that support pan/tilt can be controlled via the web interface. Multiple frame rates and resolutions are supported.

If the video stream is to be exported over the internet, it is recommended that the password be enabled. However, it must be noted that this is a simple HTTP authentication, which is sent unencrypted, and is thus not highly secure.

If prompted for the webcam password, the username is ‘webcam’.

If multiple webcams are attached, they will all start up using the same settings, except that each additional webcam will run on the next higher port number. Multiple webcams will generally only work when the resolution and framerate are set to low levels.

At this point, we have covered most of the common uses of the web interface. But the web interface offers many more configuration options. This reference section covers all of the available options. If you want to continue on to tasks such as writing and running code on the SBC, visit the [[OS - Phidget SBC]] page.

====Can I use multiple webcams?====
Probably... In theory you can connect multiple webcams to the SBC, however, the bandwidth of a USB1.1 hub will limit the amount of data you can stream meaning you might have to use reduces resolution/framerate to do it successfully.
