For automotive technicians working with Mercedes-Benz and other Daimler vehicles, Xentry/DAS is an indispensable diagnostic tool. Often, setting up this powerful software involves working within a virtual machine environment for flexibility and compatibility. A crucial step in this process is correctly configuring the Xentry Port to ensure seamless communication between your diagnostic hardware and the virtualized system. This guide provides a step-by-step approach to setting up your xentry port using a serial connection within a virtual machine, optimizing your diagnostic workflow.
To begin, you’ll need a few key components. Firstly, a reliable USB to serial adapter based on the FTDI chipset is essential for establishing the physical connection. These adapters are known for their stability and compatibility, ensuring a robust link for diagnostic data transfer. You will also require a virtual machine environment, with VirtualBox being a popular and free choice. It’s important to use a compatible virtual disk image format like VHD, especially with VirtualBox, to avoid potential compatibility issues. Finally, ensure you have your C3 operating system image properly installed within the virtual machine.
Setting up the virtual machine is your first practical step. Create a new VirtualBox machine and point it to your prepared disk image. Configure the OS settings within VirtualBox to mirror the operating system on your disk image. Once the virtual OS boots, installing VirtualBox Guest Additions is highly recommended. These additions enhance performance and integration between the host and guest operating systems. For older systems like Windows XP, ensure that APIC is enabled in the system settings of VirtualBox to prevent boot problems.
Some Xentry/DAS installations may incorporate copy protection measures that can be triggered by hardware ID changes. In Windows XP environments, you might need to disable unnecessary startup services via msconfig, such as Chinese language services or potentially problematic startup items. Removing executables related to “ads” and “mote” is also advisable. If copy protection issues persist, obtaining a clean DAS BIN folder from a non-protected source might be necessary to restore functionality.
Next, focus on identifying and configuring the xentry port. Open Star Utilities within your virtual machine and navigate to the self-tests section, then select DMI self-diagnosis. This will display a window revealing the COM port number and baud rate that Xentry/DAS is configured to use. Note down these values as they are crucial for the next steps.
Now, access the Device Manager within your virtual machine and locate the COM ports section. Identify the COM port that matches the one noted from Star Utilities. Go to its advanced settings and change its port number to the next available number. For instance, if it’s COM2, change it to COM3. This adjustment helps avoid conflicts and ensures proper routing of the xentry port communication.
Plug in your FTDI USB to serial adapter into your host computer. While driver installation on the host might not always be mandatory, it’s generally recommended. In your virtual machine, go to the Devices menu and find the USB to Serial device listed under USB. Select it to connect it to your guest operating system. The virtual machine will detect the new hardware. Install the necessary FTDI drivers within the guest OS, either before or after connecting the adapter.
Once the drivers are installed in the guest OS, return to the COM port listing in Device Manager. Locate the newly connected FTDI COM port, open its properties, and configure its Baud rate and COM port number to match the values you recorded from Star Utilities, typically 115200 and COM2 respectively. Critically, within the FTDI adapter’s advanced settings, adjust the latency timer to 1ms. This low latency is often required for reliable xentry port communication.
With the xentry port configured, connect your serial cable and then plug the multiplexer into the vehicle’s OBDII port. The status monitor within the Xentry/DAS taskbar should indicate a connection. You can verify the connection by revisiting the Star Utilities self-test menu; it should now pass. Even if the self-test fails, a “connected” status in the monitor often indicates a functional xentry port setup.
If you encounter difficulties getting the USB adapter to function directly within the guest OS, an alternative approach is to pass through the USB to serial adapter from the host. This involves modifying your VirtualBox machine configuration to add a COM port. Name this COM port as the one shown in Star Utilities, and select “Host Device.” In the path field, specify the host COM port number for your USB serial adapter (e.g., COM6). You might still need to adjust the port number within the guest OS Device Manager to ensure it aligns with the xentry port settings.
Properly configuring your xentry port is paramount for effective vehicle diagnostics with Xentry/DAS in a virtual machine. By following these steps carefully, you can establish a stable and reliable communication pathway, ensuring accurate and efficient diagnostic procedures.
