1145 User Guide

Getting Started

Welcome to the 1145 user guide! In order to get started, make sure you have the following hardware on hand:

• 1145 - 5V to ±12V Sensor Adapter
• Any Phidget with a Voltage Input port, here are some compatible products. We will be using the VINT Hub for this guide.
• USB cable and computer
• Phidget cable
• 12 Volt sensor

Next, you will need to connect the pieces:

1. Connect the ±12V sensor to the 1145.
2. Connect the 1145 to the 1018 with the Phidget cable.
3. Connect the 1018 to your computer with the USB cable.

Now that you have everything together, let's start using the 1145!

Using the 1145

Phidget Control Panel

In order to demonstrate the functionality of the 1145, we will connect it to the 1018, and then run an example using the Phidget Control Panel on a Windows machine.

The Phidget Control Panel is available for use on both macOS and Windows machines. If you would like to follow along, first 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 1145.

First Look

After plugging in the 1145 into the 1018, and the 1018 into your computer, open 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 If your Phidget is listed in red, your firmware is out of date.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.
• To find out how to convert your Voltage value into a useful quantity, check out the formulas section below.

Technical Details

General

The 1145 uses a four-pin side mounted XH connector as its input.

Formulas

In order to convert from the return voltage of the 1145 into the actual reported value of your sensor, check you specific sensor's data sheet or user guide for the formula.

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.
