• Xentry Connect main control unit
• Xentry Tab, the multi-function unit that also serves as a monitor/display
• Blu-ray drive
• Software/DVD discs
• All necessary cabling and power supplies

The Xentry Connect is essentially a task-specific PC based on a Windows operating system, on which the software runs. It has cooling fans, USB ports, an input for the power supply, a network/LAN port for initial setup, and a display showing the operating status with function buttons.

7. How Straightforward is the Xentry Setup Process?

Setting up the Xentry unit is not difficult once the various cables are connected. It starts with opening Windows and working through the self-guided Windows setup. Then, the Blu-ray unit is connected via two USB cables, and the Xentry installation DVD goes into the Blu-ray unit, where you’re asked to proceed through a self-guided configuration setup. LAN and WiFi configuration is next, as per your shop’s setup. Then, configuration settings are transferred to the Xentry Connect unit via a network cable.

The system includes expert configuration options to meet the network and internet needs of various shop setups. Once the system is set up and configured, you can use the Blu-ray update disc (every 60 days, as already mentioned). Once you insert the disc, the download process is automatic.

8. How Do You Control Xentry?

When using Xentry, it is helpful to understand the role of the various buttons and controls on the screen. Here are some of the functions of Xentry and the procedures for launching them. This is by no means a comprehensive explanation of all of the features of this innovative system, just an overview of the primary functions.

Vehicle identification, preferably by VIN, but can also be provided by model year, chassis type, body style, etc.The main navigation bar is down the left side of the screen, and the icons are listed in a logical order from top to bottom. This is done so it is intuitive to work from top to bottom when using the system. Tapping the icons activates the following:

• Diagnosis via Xentry or DAS, depending on which model series is being serviced.
• TIPS – this page, soon to be available in the U.S., requires a network connection and also a valid PAI User ID.
• WIS/ASRA net – requires the user to log into EPC net or the WIS/ASRA net server.
• EPC net – requires an online connection to EPC net or WIS/ASRA net server with password.
• System settings for language, date/time, etc.
• Exit – closes Xentry.

In addition, icons are provided for Print and Help functions.

Attaching Xentry to the vehicle is straightforward, starting with the OBD connector. The Control software will show that the Xentry Connect drive is ready. You can then open the software, tap on the Diagnostics icon, and select the model being serviced. From there you can open the diagnostics field to adjust various settings using the Diagnostics Desktop. Finally, choose the appropriate profile – Workshop Network, or Direct Connection (Service 24-hour mode).

9. What Are the Steps to Launch and Use Xentry?

To launch and actually use Xentry, you begin by identifying the vehicle you’re working on. This is done, preferably, by entering the vehicle’s VIN. However, you can also click on the appropriate vehicle model designation and select the Diagnostics icon, and Xentry will automatically pull the VIN directly from the vehicle via the OBD connection.

“Pass-thru” is accomplished with Xentry Connect. It interprets the vehicle’s software language and communicates that information to the SDS. If for some reason the VIN is not available, you can select the Passenger Car tab, then choose a model and sub-model, along with appropriate engine and transmission selection.

As you begin to enter data and task selection, you’ll note that there’s a status bar across the bottom of the screen that shows the specifics of the detail you’ve selected. Xentry retains this information even as you continue to open multiple applications, and you can always refer to this status bar to confirm the particulars of the vehicle you’re servicing.

In fact, that’s one of the helpful features of Xentry: It has combined a variety of applications into a single interface, so it is only necessary for the user to log on once and enter vehicle identification information once. This facilitates switching among multiple open Xentry applications when servicing the same vehicle, and the system will “remember” any settings that have been changed or any changes made to the vehicle, so the same up-to-date data will appear in all open applications.

Opening the diagnostics tab will open either Xentry Diagnostics or DAS depending on the vehicle being serviced. Newer models will open in Xentry Diagnostics, while older vehicles will open DAS. Xentry Diagnostics has two main views – Functions view and Control Units view, with the Functions view being the default setting. As a general rule, the default Functions view is the best choice for nearly-new vehicles, while the Control Units view is typically the most appropriate for older vehicles where targeted control unit programming is called for. There is also an icon for Special Functions that provides a pathway to information on retrofitting and conversions.

Users will be happy to know that they can perform quick tests in either Functions view or Control Units view. When using the Quick Test function, a status line will show key parameters, such as battery voltage, the status of the connection with the vehicle, and even the status of the vehicle’s ignition switch (on or off).

Today, since so many features are dependent on control units working together, it makes sense to run Xentry’s “Quick Test” of all the vehicle systems at the outset of any diagnosis, as Mercedes-Benz recommends. This will allow you to see the “big picture” and avoid chasing dead-ends. You can select “Functions View,” and the SDS will pull up the units that have control over the feature you select.

10. How Does Xentry Facilitate Efficient Diagnostics?

The Quick Test function is a viable alternative to the Guided Fault Finding (GFF) feature in Xentry – Mercedes-Benz recommends starting each diagnostic procedure with Quick Test. This is because this function typically leads you to the various related functions that a customer might describe as malfunctioning. From there you can look at “Actual Values” to examine live data and view adaptation information that a control unit has acquired. This precludes the need to use a DMM (Digital Multi-Meter) to test and record the voltage at each component’s signal line. If the live data shows a questionable voltage, you can confirm this reading by checking voltage at the actual component.

To determine whether a control unit is actually able to regulate an output, you can opt for the “Actuations” feature in Xentry. This provides a simple on/off function that allows you to manipulate a control unit to operate the driver that controls the system outputs. You’ll measure the voltage on the control side of the component and determine whether or not the control unit is able to supply power or a ground pathway to the control circuit. These functions normally must be carried out with the ignition key in the Run position and the engine off, as noted above, which reinforces the need for the use of a battery maintainer during testing.

The latest Xentry system has a “Tests” tab that expands on the previous SDS software actuations tab. You can perform static and dynamic tests for each system in a particular control unit. They will simulate the self-diagnostic functions that run automatically.

11. What Happens When Exiting Xentry?

When exiting Xentry, active programs continue to run, such as when flashing a control unit. This feature is helpful when you are connecting to another vehicle immediately after your current procedure is done. This makes it easy when working on multiple vehicles concurrently, such as when you’re waiting for one vehicle to warm up or run through certain cycles. Xentry allows multiple programs to continue to run in the background, so you can switch between vehicles as necessary.

While the Xentry Connect is taking care of its business, perhaps flashing a control unit, you can use the Tab for other purposes

When service is complete and you’re ready to sign off, the exit menu offers you three choices.

• You can exit Xentry diagnostics.
• Or, you can log off from the service, in which case all on-line applications are exited, the user is logged out, but Xentry and Xentry Diagnostics remain open.
