Interconnectivity with peripherals, DVD, GPS, and Navigation make a lot of information available to the vehicles occupants. How do we keep this going? M M !

You know from you digitaldo so because they want something exceptional. camera and video recorder that high-resolutionExceptional performance, exceptional safety, and files are huge. It is not critical that the informationexceptional technology are only some of the reasons run at real-time speeds because buffers can storebehind this. Nowhere is this more evident than in the information temporarily. But there is a lot ofthe entertainment and navigation systems. Engine information that needs to move around. A new formmanagement, ABS, stability control, etc. all have of transporting this information was necessary forto process information at high speed to make them these systems to function the way Mercedes-Benzfunction as closely to real-time as possible. When owners comes to media-based information systems, the LIGHT SPEED The answer to this digital data transfer problem is fiber-optics, which can channel large amounts of data quickly and accurately. They can operate in temperatures from -40 deg. to 85 deg. C, so they can easily withstand the interior environment of a vehicle. A fiber-optic cable can handle up to 20MB of data per second through light pulses, which must be shielded or the light will refract out of the path. Reflective cladding protects the light signal, and is also insulated with an orange outer jacket. This ensures that the pulses of light stay within the confines of the cable core. Using a fiber-optic network has more benefits than just being able to move around large amounts of data. Light pulses are impervious to electro- magnetic interference. This means the cables can be run through the vehicle with the wiring harness and high current flow will not distort the signal. Fiber-optic cable is lighter than metal wiring and requires fewer connections. Unfortunately, fewer connections means the cables are not easily serviceable. It takes special equipment to sever a connection and re-attach it. Most of the time, it is easier to replace the entire cable rather than repair it, depending on the extent of the damage. Mercedes-Benz implemented its version of a fiber-optic network called the Domestic Digital Bus (D2B). D2B operates the sound system, CD Changer, cellular telephone (now digital), voice recognition (if the car is so equipped), and Tele Aid control units. These features communicate with one another through an optical and electrical network. D2B transfers data at 5.6MB per second, well within the limits of the cable. This network follows slightly different rules from the electrical networks you are used to. Most August 2012 5
  6. 6. KCMLconventional CAN systems are wired in parallelwith each control unit transmitting and receivingdata according to priority. The D2B bus, like allfiber-optic networks, is not connected in parallel.It is connected in a "ring." The optical signaloriginates from a master and is sent to the secondcomponent in the ring through the cable. A secondfiber-optic cable leaves the second component andcarries the signal on to the third component, andso on. The final component sends the signal backto the master to complete the ring. A completering is required for the D2B to function. If thereis a break anywhere in the ring, none of thecomponents will function.EARLY TO BED, EARLY TO RISE Fiber-optic components draw a high amount ofelectrical current to operate. Not only do they have Here are two MOST connectors that plug into the CDto perform their function, but they also have to changer. There is a three-pin electrical connectorconvert electrical signals to light pulses and send for power, ground, and wake-up signal. The two-pinthem to the next component. It also has to receive plug is for the fiber-optic cable. One cable brings thesignals and interpret these light pulses coming from light-pulse message in, and the second cable sends it out to the next component. 6 Mercedes-Benz StarTuned

Each control unit that wakes up sends a responseThis requires a wake-up signal when the ignition signal on both networks as well. The master of thekey is turned on. This wake-up is achieved with D2B monitors the response from the control units onboth a fiber-optic signal and through the electrical the electrical network and compares it to the fiber-star network.

Therefore, the problem with the fiber-optic network In an effort to assist with self-diagnostics, both must be between component 3 and 4.the fiber-optic network and the electrical networkare not only awakened by the master, but each ONWARD AND UPWARDcomponent also answers back on both networks.

If the amplifier is built into the unit, the speakers will be wired to it. It will also have the radio tuner built into it. The radio tuner is not built into the display as with the older D2B network. The head unit only functions as a display and operator interface. When the driver changes the radio station or volume through the head unit, this information is passed onto the AGW through the fiber-optic network. The electrical network is only to wake up the system, put it to sleep, and assist in self- diagnostic functions. With a paid subscription to, you can access a fiber-optic cable diagram.

Thisas associated sensors, actuators, and other devices requires proper diagnostic equipment and driving the collision industry to join the scantool revolution. WHATS IN YOUR SCAN TOOL? A recent survey by the Equipment and Tool Institute (ETI) reported that approximately two-thirds of all collision facilities own and use at least one scan tool. For those who dont know ETI, it is the industry organization that communicates with Mercedes-Benz and other automakers to acquire and archive scan tool data - algorithms, protocol documents, parameter identifier matrices, diagnostic trouble codes, etc. Aftermarket tool and equipment manufacturers pay a licensing fee or annual dues to ETI to useThe Mercedes-Benz STAR Diagnostic System (SDS) Compact4 scan tool (above) selected data to develop andalong with SDS Flash subscriptions are essential to providing a complete build aftermarket electroniccollision repair. The Compact4 uses a vehicles VIN to register and verify test equipment and othervehicle-specific hardware and software data into Mercedes-Benzs server, sothat Mercedes-Benz knows exactly the configuration of each vehicle.

Robert Beckman, CEO of Blue Link Diagnostic Solutions Inc. says the "just in time" solution,developed in conjunction with IBM: • Leverages J-2534 interface devices, which Mercedes-Benz supports, to connect Mercedes-Benz vehicles in your body shop digitally to Mercedes-Benz diagnostic tools, software and equipment at a remote location, at a fraction of the capital costs that tooling up to factory level capability would entail. • Allows vehicles in a body shop to be diagnosed and repaired immediately onsite. • Provides affordable access to genuine Mercedes-Benz service information and other resources. • Utilizes the expertise of highly specialized technicians who have a thorough understanding of and experience using Mercedes-Benz service diagnostics.More information about this service can be found at www.bluelinkdiag. com, (images - BiueUnk Diagnostic solution August 2012 15
