1002 User Guide

Required Hardware

• A 1002 Voltage Output Phidget
• A device that requires or measures a 0-10V signal
• A USB Cable
• A computer

Connecting the Pieces

1. Connect the device to a pair of terminals on the 1002. Check the underside of the board to see which one is positive and which is negative.
2. Connect the Phidget to your computer using the USB cable

Testing Using Windows

Phidget Control Panel

In order to demonstrate the functionality of the 1002, 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 1002.

First Look

After plugging the 1002 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 If your Phidget is listed in red, your firmware is out of date.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 Output

Double-click on the Voltage Output object {{{2}}} in order to run the example: [[Image:{{{1}}}_VoltageOutput_Example.jpg|link=|center]]

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

• Set the output voltage by dragging the Voltage slider.

Testing Using Mac OS X

1. Go to the Quick Downloads section on the Mac OS X page.
2. Download and run the Phidget OS X Installer
3. Click on System Preferences >> Phidgets (under Other) to activate the Preference Pane
4. Make sure your device is properly attached
5. Double click on your device's objects in the listing to open them. The Preference Pane and examples will function very similarly to the ones described above in the Windows section.

Testing Using Linux

For a general step-by-step guide on getting Phidgets running on Linux, see the Linux page.

Using a Remote OS

We recommend testing your Phidget on a desktop OS before moving on to remote OS. Once you've tested your Phidget, you can go to the PhidgetSBC, or iOS pages to learn how to proceed.

Technical Details

General

Produces a voltage over -10V to +10V. This voltage will be asserted up to +-20mA (short-circuit). An error will be reported when this current is exceeded, and the voltage the customer is getting is no longer accurate. The voltage is produced with 12 bit resolution (4.8mV). The update rate or frequency of the outputs is dependant on the speed of your system.

Connections

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

Isolation

The 1002 is not isolated. All 4 channels use the same ground.

Current

The PhidgetAnalog board will limit the available current per channel at approximately 20mA. For reliable results, don’t approach this limit, as it will vary from channel to channel. For maximum accuracy, limit the current to 5mA. If more than +- 20mA of current is drawn, the device goes into a constant current supply mode. When this happens, the current will be held constant at it’s maximum value, and the output voltage will depend on the value of the load that the device is trying to drive.

If your application requires a larger current source / sink, the analog output can be used as an input to a larger external amplifier circuit.

All the power is supplied by the USB bus.
