The Mercedes Star Xentry system is a comprehensive diagnostic and programming tool essential for servicing Mercedes-Benz vehicles. This guide provides a detailed walkthrough of the Xentry Connect C5 hardware, software installation, upgrade procedures, and troubleshooting common issues. Understanding these elements is crucial for optimizing performance and ensuring accurate diagnostics.
Xentry Connect C5 Hardware Overview
The Xentry Connect C5 is not just an interface but a mini-computer with the following specifications:
- Operating System: Windows 7 32-bit Embedded
- Motherboard: HM65 Chipset
- CPU: Intel Celeron B810 (2 cores, 2 threads, 1.6GHz, 35W) – often a performance bottleneck.
- GPU: Integrated
- RAM: 4GB Samsung DDR3 1333MHz (maximum for 32-bit Windows)
- SSD: 256GB Xmore (versions with 238GB and 223GB exist)
- WiFi: Intel Centrino Advanced-N 6205 (2.4GHz and 5GHz, 300mbps)
Upgrading the CPU to a more powerful option like the Intel Core i7 2640M (2 cores, 4 threads, 2.8GHz base, 3.5GHz turbo, 35W) significantly improves Xentry’s responsiveness. This upgrade reduces the time to launch Xentry and access vehicle data. Ensure the chosen CPU’s TDP (Thermal Design Power) doesn’t exceed 35W to avoid overheating. Higher wattage processors can lead to shutdowns due to insufficient power delivery.
Xentry Software Installation and Upgrade
Software Components:
- Xentry Tab: Runs on your laptop and is part of the Xentry Kit 2. It can be installed separately or from the Xentry Kit 2 folder.
- Xentry Connect (Kit 2): Updating to the latest version (2020.06) is highly recommended for optimal functionality. This version is considered the final edition for the C5.
Xentry Connect Update Procedure:
- Prepare: Ensure the Xentry Connect is in standby mode. Download the Xentry Kit 2 2020.06 and extract it to a USB drive (minimum 32GB).
- Update Mode: Connect the power supply and the USB drive to the Xentry Connect. Simultaneously press the “red cross” and “green tick” buttons to enter update mode.
- Confirmation: Confirm “Start update” on the display with the green tick. The update process will take approximately 100 minutes.
- Completion: The Xentry Connect will indicate completion. Press the “gearwheels” button or wait for automatic shutdown.
Configuration:
After updating, configure the Xentry Connect through Xentry Control on your laptop. This involves setting up LAN, WiFi, and other network parameters.
Troubleshooting Common Issues
Boot/Update Issues: If the device gets stuck in a boot or update loop, create a bootable USB drive with standard Windows 7 32-bit (not embedded). Remove the SSD from the Xentry Connect, connect it to a laptop, and perform a Startup Repair using the USB drive. Reinstall the SSD securely, ensuring it’s firmly fastened to prevent further boot problems.
Update Errors: For any update errors, utilize the Xentry Support Tool to reset the Xentry Connect. This involves creating a reset USB drive through the Support Tool and initiating the reset process by pressing the “red cross” and “green tick” buttons simultaneously.
Display Issues: A blank display can indicate various problems, including hardware defects or corrupted BIOS. Further diagnostics may be required.
Maintenance: Regularly clean the Xentry Connect’s internal components, especially the cooling system, to prevent overheating and ensure optimal performance. Dust accumulation can significantly impact cooling efficiency.
