# Microsoft Windows
## EcMasterDemo
1. Install EC-Master
: Run `setup.exe` from EC-Master package, which will guide you through the installation process.
2. Determine the network interface
: For example the option -ndis 192.168.1.1 1 will be using the network adapter card with the IP address 192.168.1.1.
1. Connect EtherCAT® modules
: Any EtherCAT® module can be directly connected to the target system. EtherCAT® requires a 100 Mbit/s connection. If the Ethernet adapter card does not support this speed, an Ethernet switch must be used.
#### WARNING
The local IT infrastructure should not be mixed with EtherCAT® modules on the same Ethernet adapter. The EC-Master sends many broadcast packets!
1. Run the example application
: Execute EcMasterDemo.exe from `/Bin/Windows//`. At least an Ethernet Driver option has to be given.
```doscon
C:\> EcMasterDemo -ndis 192.168.1.1 1 -f D:/eni.xml -sp
```
#### SEE ALSO
[Running EcMasterDemo](gettingstarted_running-demo.html.md#running-ecdemo) for a detailed description of the demo application.

Compile and debug
> 1. Copy `*.dll`s from `/Bin/Windows/` to `/Bin/Windows//Debug` and `/Bin/Windows//Release`.
> > #### HINT
> > By copying the DLLs, they can be loaded on startup and original files are not overwritten and are retained.
> 1. Open `/Workspace/WindowsVS2015/EcMasterDemoDotNet/EcMasterDemoDotNet.csproj` in VS2015 or higher
> 2. Specify command line arguments for the project as shown above
> 3. (Adapt code,) compile, run, debug as usual
## EcMasterDemoGuiDotNet (.NET) - Microsoft Windows
1. Prerequisites
: To run the `EcMasterDemoGuiDotNet.exe`, the libraries `EcMaster.dll`, `EcMasterRasServer.dll`, `EcWrapperDotNet.dll`, `EcWrapper.dll` and `emllNdis.dll` from `Bin/Windows/x64` are needed in `Bin/Windows/x64/Release`, `Bin/Windows/x64/Debug`
2. Visual Studio C#-project
: The C#-project for VS2015 or higher is located at `Workspace/WindowsVS2015/EcMasterDemoGuiDotNet/EcMasterDemoGuiDotNet.csproj`
3. If the reference EcWrapperDotNet is missing, it must be re-added from `Bin/Windows/x64/EcWrapperDotNet.dll`
4. EcMasterDemoGuiDotNet is now prepared for Run/Debug
## OS Compiler settings
Besides the general settings from [Compiling the EcMasterDemo](gettingstarted_compiling.html.md#compile-ecdemo) the following settings are necessary to build the example application for Windows.
Extra include paths
: ```default
\SDK\INC\Windows
\Examples\Common\Windows
```
Extra source paths
: ```default
\Examples\Common\Windows
\Sources\OsLayer\Windows
```
Extra library paths to the main EtherCAT® components
: ```default
\SDK\LIB\Windows
```
## RtaccDevice for Real-time Ethernet Driver
As alternative to the NDIS based or Pcap based Ethernet Driver, an optional Real-time Ethernet Driver on Windows can be installed. The Real-time Ethernet Driver replaces the original Windows driver and also requires an extra license.
To **use the Real-time Ethernet Driver under Windows**, it is necessary to install the RtaccDevice driver included in the Real-time Ethernet Driver delivery:
1. Start the “Device Manager”
: 
2. Assign RtaccDevice to the network adapter
: 
Click on “Browse my computer for drivers”
Click on “Let me pick…”
Click on “Have Disk…”
3. Enter the directory of RtaccDevice Driver
The default folder if not changed is `\Bin\Windows\x64`
Enter the correct directory at the input box and press OK to proceed.
4. Choose the RtaccDevice Driver and click “Next” and confirm the installation
: 
Optionally modify the search location of the Real-time Ethernet Driver
Search locations for Real-time Ethernet Driver can be adjusted using the PATH environment variable.
\\newpage
The RtaccDevice must be assigned to the network adapter for Real-time Ethernet Driver usage on Windows. In this case it is exclusively bound for EtherCAT® usage.
The assignment can be reverted using the following steps:
1. Open the Windows device manager (Computer Management), then go to System devices. The RtaccDevice should be listed there:
> 
1. Right click on the RtaccDevice Ethernet Controller, then click on Properties:
> 
1. Switch to the tab “Driver”, then click the button “Update driver”:
> 
1. Click on “Browse my computer for drivers”:
> 
1. Click on “Let me pick from a list of available drivers on my computer”:
> 
> Select the network adapter and click “Next”.
The assignment is now reverted.
