Connect Your Xentry C4: A Comprehensive Guide to Wireless Setup

For automotive diagnostic professionals, the Mercedes-Benz Xentry C4 multiplexer is an indispensable tool. While traditionally connected via Ethernet cable, utilizing a Wi-Fi connection offers enhanced flexibility and mobility within the workshop. This guide provides a detailed, step-by-step approach to connecting your Xentry C4 multiplexer wirelessly, ensuring a seamless diagnostic experience.

Step-by-Step Guide to Establishing a Wireless Connection for Your Xentry C4

Setting up a wireless connection for your Xentry C4 involves a straightforward process, combining initial wired setup with wireless configuration. Follow these steps to enable Wi-Fi connectivity:

1. Essential Prerequisites

Before initiating the wireless setup, ensure you have the following in place:

• Mercedes-Benz C4 SDconnect Multiplexer: Verify you have a functional C4 multiplexer.
• Laptop or PC with Xentry/DAS Software: Ensure your computer has the diagnostic software suite properly installed.
• SDconnect Toolkit Installation: Confirm the SDconnect Toolkit, usually bundled with Xentry/DAS, is correctly installed and accessible.
• Power Source for Multiplexer: Ensure your C4 multiplexer is powered on, either through a vehicle’s OBDII port or an external 12V power supply.

2. Establishing an Initial Wired Connection

A stable, wired connection is crucial for the initial configuration of Wi-Fi settings.

1. Connect via Ethernet: Use an Ethernet cable to physically connect your C4 multiplexer to your laptop or PC.
2. Power On Multiplexer: Turn on the C4 multiplexer and wait for it to initialize.
3. Open SDconnect Toolkit: Launch the SDconnect Toolkit application on your computer.

3. Configuring Wi-Fi Settings within SDconnect Toolkit

This step involves setting up the wireless parameters for your Xentry C4 multiplexer.

1. Access Administration: In the SDconnect Toolkit interface, navigate to the “Administration” section.
2. Select Multiplexer Device: Locate and select your C4 multiplexer from the list of devices.
3. Open Configuration/Settings: Click on “Configuration” or “Settings” to access the device’s configuration options.
4. Navigate to WLAN (Wi-Fi) Settings: Find and select the “WLAN” or “Wi-Fi” settings option.
5. Choose Wi-Fi Network: From the available network list, select your desired Wi-Fi network. Ensure it’s the same network your computer is connected to for seamless communication.
6. Enter Wi-Fi Password: If your Wi-Fi network is password-protected, enter the correct password and confirm.
7. Set Connection Mode: Choose “Infrastructure Mode” for connecting via a router (recommended for most setups) or “Ad-Hoc Mode” for a direct connection to your laptop. Infrastructure mode offers better range and stability.

4. Connecting the Multiplexer to the Wi-Fi Network Wirelessly

After configuring the Wi-Fi parameters, you can switch to a wireless connection.

1. Disconnect Ethernet Cable: Unplug the Ethernet cable from both the multiplexer and your computer.
2. Restart C4 Multiplexer: Power cycle your C4 multiplexer by turning it off and then on again.
3. Allow Wi-Fi Connection: Give the multiplexer a moment to connect to the configured Wi-Fi network.
4. Verify WLAN Icon: Check the screen of your C4 multiplexer. A WLAN connection icon should appear, indicating a successful wireless connection.

5. Verifying the Wireless Connection on Your Computer

Confirm the wireless connection is recognized by your computer through the SDconnect Toolkit.

1. Re-open SDconnect Toolkit: Launch the SDconnect Toolkit on your laptop again.
2. Check Administration: Go to the “Administration” section.
3. Confirm WLAN Connection: Look for your C4 multiplexer in the device list. It should now be listed as connected via WLAN.
4. Verify Device Status: A green icon next to the device status indicates a successful and active wireless connection.

6. Testing the Connection with DAS/Xentry Diagnostics

The final step is to ensure the wireless connection works correctly with the diagnostic software.

1. Launch DAS/Xentry: Open the DAS or Xentry diagnostic software suite on your computer.
2. Initiate Vehicle Diagnostics: Attempt to run diagnostics on a Mercedes-Benz vehicle.
3. Confirm Wireless Communication: The software should now communicate with the vehicle through the wireless connection established with your C4 multiplexer.

Troubleshooting Common Wireless Connection Issues

Encountering issues? Here are some common troubleshooting steps:

• Same Network Verification: Double-check that both your laptop and the C4 multiplexer are connected to the same Wi-Fi network, especially in Infrastructure Mode.
• Reboot Devices: If the connection fails, try restarting both the C4 multiplexer and your computer. This often resolves temporary glitches.
• Firewall Check: Review your firewall settings. Ensure that the firewall is not blocking communication between your laptop and the C4 multiplexer. You may need to add exceptions for the SDconnect Toolkit or Xentry/DAS software.

By following these steps, you can effectively set up a wireless connection for your Xentry C4 multiplexer, enhancing your diagnostic workflow with greater convenience and flexibility. Enjoy the benefits of a wireless diagnostic environment!
