1052 User Guide

Required Hardware

• A 1052 PhidgetEncoder and customized USB cable
• A computer

Connecting the Pieces

1. Connect the PhidgetEncoder to your computer using the included USB cable.

Testing Using Windows

Phidget Control Panel

In order to demonstrate the functionality of the 1052, 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 1052.

First Look

After plugging the 1052 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 If your Phidget is listed in red, your firmware is out of date.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.

Encoder

Double-click on the Encoder object, labelled {{{2}}}, 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:

• Position Change: the number of ticks (or quadrature cycles) that have occurred since the last change event.
• Time Change: the amount of time in milliseconds that has elapsed since the last change event.
• Position: the total position in ticks relative to where the encoder was when the window was opened.
• Index Position: the position where the index channel was last encountered. Some encoders do not support index, check your encoder's datasheet for more information.
• Velocity: the average velocity in rotations per second. A CPR must be specified to enable this functionality.
• Specify a counts per revolution (CPR) value to enable velocity calculation.

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-high device, therefore, it will be true when connected to a high input and false when connected to ground.

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

Using Other Encoders

If you decide that the mounted encoder does not meet your requirements it is possible to use other two-bit mechanical encoders. Optical encoders with large counts per revolution should not be expected to work with this device. To change the encoder the user will have to carefully desolder and remove the existing encoder. However, if you attempt to remove the encoder the warranty willl be void and we can not offer technical support.

For assistance on desoldering techniques we recommend using any search engine on the Internet. Since your new encoder may not have the exact same pin configuration, you should use wire to connect your new encoder to the appropriate pins on the PhidgetEncoder board. We have tested the following encoders, and found that they can be used as replacements:

Manufacturer	Part Number	Description
CTS	290UAA5F201B2	2-Bit 9mm 20CPR Encoder Detent w/MO SPST
CTS	290UAA5F201B1	2-Bit 9mm 20CPR Encoder Non-Detent w/MO SPST
CTS	288V232R161B2	2-Bit 16mm 16CPR Encoder Detent w/MO SPST

Note: Most of the above components can be bought at Digikey.
