1144 User Guide

Required Hardware

• A 1144 12V Sensor Adapter
• An InterfaceKit or Hub to read the adapter
• A Phidget cable
• A USB cable
• A computer
• A 12V sensor

Connecting the Pieces

1. Connect the 12V sensor to the adapter.
2. Connect the adapter to the InterfaceKit or Hub with the Phidget cable.
3. Connect the InterfaceKit or Hub to your computer with the USB cable.

Testing Using Windows

Phidget Control Panel

In order to demonstrate the functionality of the 1018, 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 1018.

First Look

After plugging the 1018 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 If your Phidget is listed in red, your firmware is out of date.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: [[Image:{{{1}}}_VoltageInputSensor_Example.jpg|center|link=]]

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.

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

Interfacing a CE Transducer

To interface with a CE transducer sold at Phidgets Inc., simply connect the wires as shown in the following image.

Interfacing a 12V NPN Sensor

Left: Connection using an analog input and a pull-up resistor.
Right: Connection using an analog input and a digital input.

In order to interface with a 12V sensor with an NPN output, you need a 12V sensor adapter and an Interface Kit. There are two ways to connect them, as shown in the figures. The first way simply involves connecting the 12V sensor adapter to an analog input on the Interface Kit, and then attaching the 12V sensor to the adapter with a 10kΩ pull-up resistor placed across the +12V and analog signal lines, as pictured. There should be two 10kΩ resistors packaged with your 12V sensor adapter.

When using this setup, the voltage input will show a voltage of about 5V when the NPN sensor is open, and a much lower value (less than 1V) when the sensor is closed. Likewise, if you're using an active-low digital input, the input will be low when the NPN sensor is open, and high when it is closed.

Interfacing a 12V PNP Sensor

Connection using an analog input and a pull-down resistor.

In order to interface with a 12V sensor with an PNP output, you need a 12V sensor adapter and an Interface Kit. Simply connect the 12V sensor adapter to an analog input on the Interface Kit, and then attach the 12V sensor to the adapter with a 10kΩ pull-down resistor placed across the ground and analog signal lines, as pictured. There should be two 10kΩ resistors packaged with your 12V sensor adapter.

Formulas

The 1144 returns a voltage between 0 and 5 volts. Check the documentation for your specific sensor to determine the formula for converting from return voltage to the measured value.

Phidget Cable

The Phidget Cable is a 3-pin, 0.100 inch pitch locking connector. Pictured here is a plug with the connections labelled. The connectors are commonly available - refer to the Analog Input Primer for manufacturer part numbers.
