1 Create a C# project 1.1 Open Visual Studio IDE and create a new C# console project.
2 Import Libraries 2.1 Right-click on the reference and select Add Reference in the solution explorer 2.2 Click on the Browse button and go to the path of "<Program Files>\IVI Foundation\IVI\Bin\Primary Interop Assemblies" and choose Ikonix.EEC8500.Interop.dll, Ivi.Driver.Interop.dll and Ivi.ACPwr.Interop.dll.
2.3 Declare to use the name spaces for the interop assemblies that are specified to reference in the previous section.
using Ikonix.EEC8500.Interop;
3 Start programming 3.1 Create an object of the driver and use the initialize method to build up the connection.
var driver = new EEC8500(); driver.Initialize("ASRL5::INSTR", true, false,"QueryInstrStatus=true, DriverSetup=BaudRate=115200");
For more detail for the parameters of the Initialize() method, please refer to the help document, EEC8500.chm, which is located at "<Program Files>\IVI Foundation\IVI\Drivers\EEC8500". The first parameter ResourceName is a string type and indicates the interfaces type and address of the connection. The resource name,"ASRL5::INSTR", represents a serial port with address 5. For example, a GPIB connection could be "GPIB0::8::INSTR". For TCP/IP connection, it will be in the format of "TCPIP0::192.168.0.1::10001::SOCKET". The 10001 is the TCP/IP connection port of EEC8500. If you use serial port to connect to device, please follow the above example, "DriverSetup=BaudRate=115200", to setup the baud rate. There are other parameters for the option of the Initialize() method, please refer to the EEC8500.chm for more detail. For

example, "QueryInstrStatus=true" makes the session automatically query the error status for each command was sent.
3.2 Create file and setup test
// Create/Edit File in Manual mode driver.Execution.SetOperationMode(EEC8500OperationModeEnum.EEC8500OperationModeManual); Console.WriteLine(driver.Execution.GetOperationMode().ToString()); try {
driver.ManualMode.File.Add("IVITEST"); } catch (System.Runtime.InteropServices.COMException e) {
// It will return an error if the file was already existed. Console.WriteLine("Cannot Create a Manual File with Name, 'IVITEST'. "); } finally { driver.ManualMode.File.Edit("IVITEST"); }
// Confugure the parameters // driver.ManualMode.Couple = EEC8500CoupleEnum.EEC8500CoupleACDC; driver.ManualMode.Waveform = EEC8500WaveformEnum.EEC8500WaveformSINE; driver.ManualMode.Range = EEC8500RangeEnum.EEC8500RangeAuto; driver.ManualMode.VoltageAC = 100; driver.ManualMode.VoltageDC = 10; driver.ManualMode.Frequency = 62; driver.ManualMode.RampUp = 0.5; driver.ManualMode.CurrentHighLimit = 10; driver.ManualMode.CurrentLimitDelay = 10; driver.ManualMode.PowerHighLimit = 12; driver.ManualMode.StartAngle = 180;
For the EEC8500, all of the test parameters would be within a file. Therefore, you need to create a file first and then setup the parameters. Also, there are many difference between Standard and Advanced levels of EEC8500. In this example, the configurations of CoupleACDC, Waveform, CurrentLowLimit and PowerLowLimit are not available in the Standard level of EEC8500.
3.3 Load file and start a test
// Output and Measure // driver.ManualMode.File.Load("IVITEST"); driver.OutputPhases.Item["PhaseA"].Enabled = true;
Before running output, you have to select a file to load. And then invoke driver.OutputPhases.Item["PhaseA"].Enabled method to start a test.
3.4 Measure during test
for (int i = 0; i < 20; i++) {
Console.WriteLine("Output State: {0}", driver.Measure.State()); Console.WriteLine("Measure All: {0}", driver.Measure.All()); } driver.OutputPhases.Item["PhaseA"].Enabled = false;

This while loop would run with the condition of state is testing. Using the methods of Measure subsystem could let you read the immediate readings. 3.5 Close the session
driver.OutputPhases.Item["PhaseA"].Enabled = false; driver.Close(); Console.WriteLine("Done - Press Enter to Exit"); Console.ReadLine();
Close() would close the I/O session to the instrument. 4 Completed example

5. Getting Started with LabVIEW
Introduction
This chapter describes the procedures of using the IVI-COM driver of Ikonix Group by LabVIEW programming language. In this exercise, the programmer could learn how to import the driver and complete a short program controlling the device step-by step.
Even though the programmers could control the device by IVI Driver. For the LabVIEW programmer, we suggest that using LabVIEW plu&play driver would be easier for your programming and debugging. The LabVIEW driver from Ikonix Group are all made up with commands directly, so you could clearly check how the commands were sent to instruments.

6 Create an Invoke Node function and connect the reference to the output of Automation Refnum and then click on the Method and select Initialize to initialize the connection with device.
For more detail for the parameters of the Initialize() method, please refer to the help document, EEC8500.chm located at "<Program Files>\IVI Foundation\IVI\Drivers\EEC8500". The first parameter ResourceName is a string type and indicates the interfaces type and address of the connection. The resource name,"ASRL7::INSTR", represents a serial port with address 4. For example, a GPIB connection could be "GPIB0::8::INSTR". For TCP/IP connection, it will be in the format of "TCPIP0::192.168.0.1::10001::SOCKET". The 10001 is the TCP/IP connection port of EEC8500. If you use serial port to connect to device, please follow the above example, "DriverSetup=BaudRate=115200", to setup the baud rate. There are other parameters for the option of the Initialize() method, please refer to the EEC8500.chm for more detail. For example, "QueryInstrStatus=true" makes the session automatically query the error status for each command was sent. 6.1 Switch operation mode
Before we create a Manual Mode file on the EEC8500 power supply, we have to switch the operation mode to Manual Mode. The SetOperationMode() method is under the Execution interface. Please be noted that only the Advanced level of 8500 supports the Step, Pulse and Library modes.

6.2 Create file and setup test
Use the Property Node to get reference of the sub-system of IEEC8500 class. For example, File is one of the sub class of IEEC8500.ManualMode, and then we could use the Add method under File to create a file in the device.
For the EEC8500, all of the test parameters would be within a file. Therefore, you need to create a file first and then select a file to be edited. Also, there are many differences between Standard and Advanced levels of EEC8500. In this example, the configurations of CoupleACDC, Waveform are not available in the Standard level of EEC8500. Please be noted that the flow of error data could make sure that the procedure ran sequentially.

6.3 Load file and start a test
Before running output, you have to select a file to load. And then invoke driver.OutputPhases.Item["PhaseA"].Enabled property to start a test with a Boolean value. The OutputPhases class is one property of the IEEC8500 class. The function of Item["PhaseA"] is the method of OutputPhases. This method inherits the IviACPwr class, it provides the features for multiple phases, however, the EEC8500 provides only single phase capability. 6.4 Measure during test
This for loop would run with polling the state and meters. Using the methods of Measure subsystem could let you read the immediate readings. Measure is one property of IEEC8500, and All is a method of Measure class. It will return the measurements in a raw string. 6.5 Stop and close the session
The above procedure which is similar with the output procedure shows how to stop output, just to set the Enable property to False.
Close method in IEEC8500 class would close the I/O session to the instrument. Also, all of the references should be closed using the Close Reference function.

7 Completed example
The completed example for your reference which are located at the path of <Program Files>\IVI Foundation\IVI\Drivers\EEC8500\Examples, including C#, C++ and Python as well. However, we suggest that using LabVIEW plug & play driver would be easier for LabVIEW developers. If you need a LabVIEW driver, please download it from the website of IKONIX or contact the vendor.
