== Part 2: Using Your Phidget ==

===About===
The VINT Hub provides a stable interface to connect your devices to your computer via USB. The VINT Hub has 6 ports. Each port can:

* Connect to a VINT Device 
* Read a 0-5V Voltage or ratiometric sensor (connect to Analog Input sensors)
* Act as a digital output (control LEDs, relays, digital circuits, and other simple electronics)
* Act as a digital input (read the state of a switch)

The HUB0002 has improved performance on some newer VINT devices. For more details, see the Advanced Topics section at the bottom of this page.

===Explore Your Phidget Channels Using the Control Panel===

The VINT Hub is a connecting point between your computer and device allowing for simple communication. You can use your Control Panel to view your attached Phidgets. Explore the 5 types of connections bellow: 

{{UGC-Start}}

VINT Devices like the TMP1101 or DCC1003 are Phidgets that digitally communicate with the VINT Hub. Each device will have unique features, so it is recommended you visit the individual product page for more details.

When attached correctly these Phidgets will appear by name in your Control Panel, with each channel listed below the name. For example, when the HUM1000 is attached you will see:

[[Image:vint-di.jpg|350px|link=]]

'''Digital Input''' is one of the VINT Hub’s built-in Channel Classes. Any of the these ports can act as an active-low digital input, making them useful for reading switches and buttons. The above image provides an example of how to wire a switch to be used with the VINT Hub.

If you open '''Digital Input Mode''' in the Control Panel you will be able to see the state of your button/switch.

{{UGC-Entry| Digital Output:| control LEDs, relays, digital circuits, and other simple electronics
|
[[Image:vint-do.jpg|350px|link=]]

'''Digital Output''' is one of the VINT Hub’s built-in Channel Classes. Any of these ports can be used as a 3.3V digital output, making them useful for blinking LEDs. The above image demonstrates how to connect your LED to be used with the VINT Hub.

Open '''Digital Output Mode''' in the Control Panel to control the 3.3V output.

{{UGC-Entry| Voltage Input:| Non-ratiometric Analog sensors and monitoring 5V digital circuits
|
[[Image:vint-vi.jpg|350px|link=]]

'''Voltage Input''' is one of the VINT Hub’s built-in Channel Classes. Any of these ports can be used to read voltage, making them great for reading non-ratiometric sensors and monitoring 5V digital circuits.

Open '''Voltage Input Mode''' in the Control Panel to view your device’s output voltage.

{{UGC-Entry| Voltage Ratio Input:| Analog ratiometric sensors
|
[[Image:vint-vr.jpg|350px|link=]]

'''Voltage Ratio Input''' is one of the VINT Hub’s built-in Channel Classes. Any of these ports can act as a Voltage Ratio Input comparing the voltage provided to the voltage returned by the device, making it useful for connecting ratiometric sensors. The voltage ratio is reported in Volts per Volt. For example, if the Phidget is providing 5V and the sensor is sending back 2.5V, the ratio will be 0.5V/V.

Open '''Voltage Ratio Input Mode''' in the Control Panel to view your device’s voltage ratio.

{{UGC-Entry|High-speed VINT Ports [[Image:speedicon_t.png|link=|25px]]|
|
[[Image:hispeed2.jpg|link=|right]]
All six ports on the HUB0002 support increased communication speed with some newer VINT devices, denoted by a [[Image:speedicon.jpg|link=|25px]] icon printed next to the ports. You can set communication speeds of up to 1Mbps, which will allow shorter data intervals. The communication speed is modified in the device API, not the Hub, so you can refer to the {{Phidget22API}} for the device for more information on how to set the communication speed. You can also set communication speed by right-clicking the device name in the control panel when it is plugged into a VINT port that has the [[Image:speedicon.jpg|link=|25px]] icon.

{{UGC-Entry|Improved Immunity and Maximum Cable Length [[Image:shieldicon_t.png|link=|25px]]|
|
The HUB0002 provides improved immunity to electromagnetic interference on the Phidget Cable connection when used with some newer VINT devices. If the device has a [[Image:shieldicon.jpg|link=|25px]] icon printed on the enclosure, the connection will have improved immunity when used with any of the HUB0002's six VINT ports. 

As a result, the maximum possible length of the Phidget cable between the VINT Hub and device is potentially increased to as much as 50 meters. The actual maximum distance increase varies depending on the power consumption of the device. If your device has the [[Image:shieldicon.jpg|link=|25px]] printed on its enclosure, you can check the specifications tab on the product page for cable length limits depending on the gauge of wire used.

{{UGC-Entry|Setting the Device Label|
|
When opening channels with Phidgets, you can set several properties to make sure you are accessing the precise channel you want. The HUB0002 has a unique serial number that can be used to find its ports or any VINT devices connected to them. If you want something more customizable and human-readable, you can use the [[Addressing_Phidgets#Label|device label]] instead. You can customize the device label by using {{code|writeDeviceLabel}} on the {{code|Hub}} object after it has been opened.

With the device label, you can address any of the VINT Hub's channels, or any connected VINT device channels. The device label will remain after the VINT Hub is unplugged as it is stored in flash memory.}}
