Getting Started

Checking the Contents

You should have received: A PhidgetAnalog 4-Output A Mini-USB cable A Hardware Mounting Kit

In order to test your new Phidget you will also need: A device requiring a 0 to 10V signal A multimeter could also be used to monitor the output voltage

Connecting the Pieces

Connect your device to the PhidgetAnalog board using one of the terminal blocks. Connect the PhidgetAnalog 4-Output to your computer using the Mini-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 Phidget Control Panel; we will use this program to ensure that your new Phidget works properly.

The source code for the Analog-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.

API

We document API Calls specific to this product in this section. Functions common to all Phidgets and functions not applicable to this device are not covered here. This section is deliberately generic. For calling conventions under a specific language, refer to the associated API manual. For exact values, refer to the device specifications. ===Functions

Properties

int OutputCount() [get]

Gets the number of analog outputs supported by the PhidgetAnalog.

double Voltage(int OutputIndex) [get, set]

Gets or sets the current voltage output setting for an analog output, in Volts. The range is VoltageMinVoltageMax. Voltage is not actually applied until Enabled is set to true.

double VoltageMin(int OutputIndex) [get]

Gets the minimum supported output voltage, for an output, in Volts.

double VoltageMax(int OutputIndex) [get]

Gets the maximum supported output voltage, for an output, in Volts.

bool Enabled(int OutputIndex) [get, set]

Gets the enabled state for an output. When enabled, the output drives at the set Voltage, up to 20mA. When disabled, the output is tied to ground via a 4K pull-down.

Events

OnError(int ErrorCode, String ErrorDescription)

The PhidgetAnalog will throw error events under certain circumstances:

ErrorCode = EEPHIDGET_OVERCURRENT - An overcurrent condition has occured on an output. Under this condition, the output is clamped to 20mA.

ErrorCode = EEPHIDGET_OVERTEMP - A Thermal Shutdown state has occured. The outputs will be shut down under this condition.

When overcurrent or overtemperature state have ended, there will be an error event with the EEPHIDGET_OK code.

See the ErrorDescription string for specific error details
