==Getting Started==
Before you get started with plugging in and setting up your VINT Hub, we recommend downloading our libraries from [[Operating_System_Support|here]].

==Using the HUB0000==

This table will help you decide where to look next to get your devices plugged in and running:

[[#VINT Device| VINT Device Mode]]

[[Image:vint-v.jpg|350px|link=#VINT Device]]

This mode is for connecting to a VINT device. These devices differ from analog sensors because instead of just reporting 0 to 5 volts, they communicate with the VINT Hub. The communication is digital, therefore it is immune to electrical interference between the hub and the device.

|
[[#Digital Input | Digital Input Mode]]

[[Image:vint-di.jpg|280px|link=#Digital Input]]

In digital input mode, the VINT Hub port can act as an active-low digital input. This mode is great for reading the state of buttons and switches. 

|
[[#Voltage Ratio Input | Voltage Ratio Input Mode]]

[[Image:vint-vr.jpg|280px|link=#Voltage Ratio Input]]

In voltage ratio input mode, the VINT Hub port will read the voltage on the white wire and compare it to the voltage being supplied on the red wire. This mode will let you read any ratiometric Phidgets sensor.
|-
|

[[#Voltage Input | Voltage Input Mode]]

[[Image:vint-vi.jpg|280px|link=#Voltage Input]]

In voltage input mode, the VINT Hub port will read the voltage on the white wire. This can be used to interface a non-ratiometric sensor, or to measure the voltage in a 5V digital circuit.
|
[[#Digital Output | Digital Output Mode]]

[[Image:vint-do.jpg|280px|link=#Digital Output]]

In digital output mode, a VINT Hub port can behave like a 3.3V digital output. You could use this mode to blink an LED or switch on a MOSFET. And don't worry if you still need a 5V digital output; there are VINT modules available that provide multiple 5V digital outputs on a single VINT port.

===VINT Device===
[[Image:HIN1101_Functional.jpeg|300px|right|link=]]
A VINT Device is any Phidget that must be controlled by a VINT Hub instead of plugging directly into your computer via USB. You can find a complete list of VINT devices {{CT|VINTDevice|here}}. 

When you double click on an VINT Device in the control panel, a window will open with controls and readouts for that specific class of Phidget. For instructions on how to use this example, find the '''[[:Category:UserGuide|user guide]]''' for that Phidget.

===Digital Input===

====Using the Digital Inputs====
Here are some circuit diagrams that illustrate how to connect various devices to the digital inputs on your Phidget.

=====Wiring a switch to a Digital Input=====
[[Image:vint-di.jpg|300px|right|link=|]]
Connect the switch between the white and black wires of a Phidget cable, and plug the cable into a VINT port. Wiring the switch this way will make the input TRUE when the switch is closed, and FALSE when the switch is open.

====Using the Control Pannel====

Double-click on a Digital Input object in order to run the example:

===Digital Output===
====Using the Digital Outputs====
Here are some diagrams that illustrate how to connect various devices to the digital outputs on your Phidget.

=====Driving an LED=====

[[Image:vint-do.jpg|link=|300px|right|Diagram for connecting to an LED.]]
Connecting an LED to a digital output is simple. Wire the anode (long side) to the white wire on the Phidget cable, and the cathode to the black wire of the Phidget cable. If you wire it backwards, the LED will not light but no harm will come to the system.

===Voltage Input===
====Using the Voltage Inputs====

Here are some examples of how you can connect various devices to the voltage inputs on your Phidget:

[[Image:Sensor_Voltage_Input.jpg|right|link=|400px|Diagram for connecting to a Phidget sensor]]
=====Connect a Sensor=====
Connecting to a Phidget sensor is as simple as plugging it into the [[What is VINT?|VINT Port]] with a Phidget cable.
<br clear="all">

====Using the Control Pannel====

Double-click on a Voltage Input object in order to run the example:
[[Image:HUB0000_VoltageInputSensor_Example.jpg|center|link=]]


{{UGExampleDescription}}
*Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the [[Data_Rate_and_Change_Trigger|data interval/change trigger]] page.
*If you have an analog sensor connected that you bought from us, you can select it from the ''Sensor Type'' drop-down menu. The example will then convert the voltage into a more meaningful value based on your sensor, with units included, and display it beside the ''Sensor Value'' label. Converting voltage to a ''Sensor Value'' is not specific to this example, it is handled by the Phidget libraries, with functions you have access to when you begin developing!

===Voltage Ratio Input===
====Using the Voltage Ratio Inputs====

Here are some examples of how you can connect various devices to the voltage ratio inputs on your Phidget:

[[Image:Sensor_Voltage_Ratio_Input.jpg|right|link=|400px|Diagram for connecting to a Phidget sensor]]
=====Connect a Sensor=====
Connecting to a ratiometric sensor is as simple as plugging it into the [[What is VINT?|VINT Port]] with a Phidget cable.

====Using the Control Pannel====
Double-click on a Voltage Ratio Input object in order to run the example: 
[[Image:HUB0000_VoltageRatioSensor_Example.jpg|link=|center]]

{{UGExampleDescription}}
*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. 
*Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the [[Data_Rate_and_Change_Trigger|data interval/change trigger]] page.
*If you have an analog sensor connected that you bought from us, you can select it from the Sensor Type drop-down menu.

===Using Your Own Program===

You are now ready to start writing your own code for the device. The best way to do that is to start from our examples:

The the HUB0000 can be used by itself with the {{ExampleLink|DigitalInput}}, the {{ExampleLink|DigitalOutput}},  the {{ExampleLink|VoltageInput}}, and the {{ExampleLink|VoltageRatioInput}}. To find examples for a Phidget connected to the HUB0000, look at its '''User Guide''' for more information.

Once you have your example, you will need to follow the instructions on the page for your programming language to get it running. To find these instructions, select your programming language from the [[Software_Overview#Language_Support|Software Overview]] page.

==Technical Details==

===VINT Ports===

For more information on the capabilities of the ports on the VINT Hub, see the [[What_is_VINT%3F|VINT Primer]].

===Setting the Device Label===

When opening channels with Phidgets, you can set a number of properties to make sure you match the precise channel you want. The HUB0000 has a unique serial number which 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 [[Using_Multiple_Phidgets#Using_the_Label|device label]] instead. You can customize the device label by using {{Code|writeDeviceLabel}} on the {{Code|Hub}} object after it's been opened.

Once a device label has been written, you can use it to address any of the VINT Hub's channels, or the channels of any VINT device connected to the hub.
