Connecting the Pieces

Connect the PhidgetEncoder board to the computer using the USB cable.

Testing Using Windows 2000 / XP / Vista / 7

Make sure you have the current version of the Phidget library installed on your PC. If you don't, follow these steps:

1. Go to the Quick Downloads section on the Windows page
2. Download and run the Phidget21 Installer (32-bit, or 64-bit, depending on your system)
3. You should see the icon on the right hand corner of the Task Bar.

Running Phidgets Sample Program

Double clicking on the icon loads the Phidget Control Panel; we will use this program to ensure that your new Phidget works properly.

The source code for the Encoder-full sample program can be found in the quick downloads section on the C# Language Page. If you'd like to see examples in other languages, you can visit our Languages page.

Updating Device Firmware

If an entry in this list is red, it means the firmware for that device is out of date. Double click on the entry to be given the option of updating the firmware. If you choose not to update the firmware, you can still run the example for that device after refusing.

Double Click on the icon to activate the Phidget Control Panel and make sure that the Phidget Encoder is properly attached to your PC.		File:1052 0 Control Panel Screen.jpg
Double Click on Phidget Encoder in the Phidget Control Panel to bring up Encoder-full and check that the box labelled Attached contains the word True. As you turn the knob the relative change will be positive when turning counterclockwise and negative when turning clockwise. Displays the time in milliseconds since the last time you turned the knob. Returns 80 counts for each knob revolution. The number will decrease when turning the knob clockwise and increase when turning counterclockwise. Tick mark appears when the knob is depressed.

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 that the Phidget Encoder is properly attached.
5. Double Click on Phidget Encoder in the Phidget Preference Pane to bring up the Encoder-full Sample program. This program will function in a similar way as the Windows version.

Using Linux

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.
