1019 User Guide

Getting Started

Welcome to the 1019 user guide! In order to get started, make sure you have the following hardware on hand:

• 1019 Phidget InterfaceKit
• USB cable and computer
• power supply
• something to use with the 1019 (e.g. LEDs, switches, analog sensors, etc.)

Next, you will need to connect the pieces:

1. Connect any sensors to the voltage inputs on the 1019.
2. Connect the 1019 to the computer using a USB cable.
3. Connect a switch or a piece of wire connecting ground to one of the digital input terminals.
4. Connect an LED to one of the digital outputs by inserting the long LED wire into the digital output 0 and the shorter wire into ground.
5. Connect the power supply to the barrel jack.
6. If your power supply does not have a barrel connector, you can connect the wires to the terminal block beside the jack. Be careful to observe correct polarity when connecting the power supply's cables.
7. You can connect other USB devices to the USB hub.

Now that you have everything together, let's start using the 1019!

Using the 1019

Phidget Control Panel

In order to demonstrate the functionality of the 1019, the Phidget Control Panel running on a Windows machine will be used.

The Phidget Control Panel is available for use on both macOS and Windows machines.

Windows

To open the Phidget Control Panel on Windows, find the icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel

macOS

To open the Phidget Control Panel on macOS, open Finder and navigate to the Phidget Control Panel in the Applications list. Double click on the icon to bring up the Phidget Control Panel.

For more information, take a look at the getting started guide for your operating system:

• Getting started with Windows
• Getting started with macOS

Linux users can follow the getting started with Linux guide and continue reading here for more information about the 1019.

First Look

After plugging the 1019 into your computer and opening the Phidget Control Panel, you will see something like this:

The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:

• Serial number: allows you to differentiate between similar Phidgets.
• Channel: allows you to differentiate between similar objects on a Phidget.
• Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.

The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.

Voltage Input

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

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

• Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the 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!

For more information about Voltage Inputs, check out the Voltage Input Primer.

Voltage Ratio Input

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

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

• 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 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!

Digital Input

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

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

• This is an active-low device, therefore, it will be true when connected to ground, and false when connected to a high voltage.

For more information about Digital Inputs, take a look at the Digital Input Primer

Digital Output

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

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

• Toggle the state of the digital output by pressing the button.

Technical Details

Powering the PhidgetInterfaceKit

The 1019 is not powered from the PC-USB bus. An external 6-15V supply must used to power the 1019 and any attached USB devices. However, the USB hub will not actually be powered until a USB connection is made. The reason for this is that the voltage regulator chip on the 1019 is what routes power to the hub, and it gets its power from the USB line. The 1019 will consume a maximum of 10mA from the USB host cable - allowing it to be directly connected to small hosts that do not provide full USB power.

Connecting additional USB devices to the 1019 is as easy as plugging them into the on-board 6-port hub. Each USB port on the hub has a maximum current supply of 500mA. Ensure the power supply selected has a high enough current output to supply the required current to all external USB devices as well as the 1019 and any sensors or devices connected to it. The worst case requirement is 3 Watts input power per USB device. A 24 Watt 12VDC / 2 Amp power supply is provided with the 1019 - more than sufficient.

The USB Hub actually has 7 ports, but only 6 of them are used for connecting additional devices since one port is dedicated to the internal 8/8/8 InterfaceKit.

The USB Hub is a full-speed hub with a transfer rate of 12Mbits/second. We chose to go with a full speed implementation since it is fast enough to handle traffic from Phidgets; an added benefit is lower power consumption.

To summarize the power distribution of this board:

• Each USB port has 500 mA available
• All analog inputs share a total of 500 mA
• The digital outputs, +5V terminals, USB controller, and pull-ups all share a total of 500 mA
• The power inbound from the USB line does not contribute to any of the above

Connections

The ports and terminal blocks on this board are labelled on the underside to save space:

Chaining the USB Hubs

The 1019 follows USB specifications and can be daisy chained to the maximum hub depth of 5. A sixth 1019 with a hub plugged into the fifth hub will not be usable at all because the 1019 portion is connected after the hub. However, other Phidgets plugged into the fifth hub will operate normally.
