Workshop Network Connection

The DISplus has the ability to be integrated into an existing workshop computer network. Networking allows the DISplus to be connected to the same server as the DCS 2000 system.

Having all of the BMW centers diagnosis equipment on a network, provides BMW with a method of immediate retrieval of data from vehicle systems that are being diagnosed in the workshop.

The benefits are, to provide BMW with a better, more complete and in-depth understanding of diagnostic problems and the conditions of diagnosable systems. Also, this information will be used by the Hotline and by Service Engineering to support BMW centers, as well as for product improvement and development.

In addition to reporting, the DISplus will add a web browser feature. This will enable technicians to toggle over to the internet and view information on the technical website.

The Workshop Network consists of

1. DISplus
2. Ethernet drop from the BMW center's DCS 2000 LAN
3. Switched hub
4. Ethernet Access point with RF transceiver
5. Diagnostic bay(s) wired with 3 Ethernet 10base-T connections
6. Technical Reference PC (located in the workshop)
7. Network Printer: Lexmark M410N post script printer
8. I/P address for each device on the Ethernet

Identifying Workshop Network. Scheme 597

Network Terms Defined

Ethernet

Originally developed by Xerox(tm), Ethernet is the most widely used LAN technology. An Ethernet LAN typically uses coaxial cable or twisted pair wiring. The most common Ethernet systems are called 10 base -T and provide transmission speeds up to 10Mbps.

Internet Protocol (I/P) Address

An Internet Protocol address is a binary number that identifies each sender or receiver of information that is sent across the internet or LAN. The I/P address is usually expressed as four decimal numbers, each representing eight bits, separated by periods i.e. 192.168.68.20. The numbers and their sequence provide information to the Network about which specific device or Host is sending or receiving a message.

Local Area Network (LAN)

A local area network is a group of computers and devices that share a common communications line and may share the resources of a single server within a small geographic area i.e. within a Dealership. Shared programs can be kept on the LAN server and be accessed by individuals on the LAN. Also, for example, users can order printing from one centrally located printer attached to the LAN.

10base-T

Most Ethernet wiring uses ordinary twisted pair phone line to transfer data within a LAN. The designation, 10base-T is an Institute of Electrical and Electronics Engineers shorthand. "10" refers to the transmission speed of 10Mbps (megabits per second). Base means that only Ethernet signals are carried on the line. "T" represents twisted pair. There are other media used to transfer Ethernet signals that can use coaxial cable or fiber optical cable.

1. Attach the diagnostic cable to the head. The cable will only fit in the correct socket. NOTE: Use the correct cable according to the type of diagnosis socket that the vehicle has (16 pin OBD II or BMW 20 pin under the hood). (Scheme 598): Attaching Diagnostic Cable To Head
2. Connect the diagnostic cable to the vehicle.
3. Turn on the ignition.
4. As a test, all three LEDs will illuminate. The green LED should stay illuminated to indicate that the head is receiving operating power.
5. The amber LED will flash until a connection to the DISplus can be established. (Scheme 599): Connecting Diagnostic Cable To Vehicle
6. As soon as the LAN connection with the DISplus is established, the flashing amber LED will change to a steady light.
7. Connection to the Diagnostic Head of the DISplus can be confirmed and created from the "Connection Setup" screen of the Administration page.
8. If Radio-LAN communication with the Diagnostic Head is not possible, a hardwire cable connection may be made.
9. Connect the DK LAN cable as shown in the illustration (orange connector).
10. On the DISplus, disconnect the SE LAN cable (the one connecting the DISplus to the network). Connect the other end of the DK LAN cable (that looks like a phone connector) to the DISplus LAN receptacle. (Scheme 600): Connecting DK LAN Cable
11. Restart the Head by briefly disconnecting and connecting it to the vehicle to initialize communication.

Connection Setup (Administration)

2. Any Heads that are powered up and not currently assigned to a DISplus will be found and listed in the box. Each head has its own I/P address for identification to the DISplus. (Scheme 602): Identifying Administration Menu Display
3. With the correct Diagnostic Head identified, press the "Connecting" button to establish the connection.
4. Once the radio LAN link is established, the DISplus will only be able to communicate with that head. If the use of another head is desired, press the "Quit Connecting" button from the same page. This breaks the link. Repeat the process for selecting and connecting as previously described.

Checking The Operation LED Indicators Of The Access Point

If communication between the Diagnostic Head and the DISplus is faulty, the LEDs on the access point may help to determine where the problem is. The indicators operate as follows

Scheme 603

1. Status LED: During normal operation the LED flashes once per second.
2. Serial LED: Flashes during activity at the serial interface.
3. Cable LAN connected LED: "ON" indicates a valid Ethernet LAN connection.
4. Cable LAN active LED: Flashes when data is being transmitted via the LAN.
5. Radio LAN connected LED: Lights up when there is an established connection between the Diagnostic Head and the access point (Scheme 603): Checking Operation LED Indicators Of Access Point
6. Radio LAN active: During connection setup and when data is being transmitted by the Diagnostic head, this LED flickers.

Oscilloscope Function

The oscilloscope function of the DISplus uses a digital dual trace display screen. There are two methods for setting up the scope to display a pattern: manual setup or preset measurements.

The oscilloscope setting screen is used to manually select how the measured signal will be displayed.

Identifying Two Channel Set Up Panels For Dual Trace Oscilloscope. Scheme 657

Once the settings are complete and the test connections are made the oscilloscope graph may be viewed by selecting the "Oscilloscope display" button.

The oscilloscope signal pattern may be adjusted by manipulating the voltage level and the trigger level (voltage) from within the display screen. If the displayed pattern is still unreadable or incorrectly setup, the oscilloscope settings can be further adjusted by returning to the settings screen.

Oscilloscope Display Screen Features

Once the signal pattern is displayed, the pattern may be locked on the screen with the "Hold screen" button or with the freeze image buttons on the test cable leads.

Holding the image will activate the "Cursor", "Zoom" and "Memory" features. Holding the image also allows the signal pattern to be visible when printing the screen.

Cursor 1 And 2

This feature is used to measure the amplitude and time differential of the signal pattern. Activate the feature by pressing the Cursor 1 button first. A vertical line will appear. Roughly position the line by touching the desired measurement point on the screen.

Anywhere the cursor line intersects the signal pattern, the amplitude value at that point will be displayed in a box on the right of the display screen. If both traces of the scope are being used, (both channel A and B) each value will be shown in its own box. A fine adjustment may be made to the cursor line by using the arrow buttons to the left and right of the cursor buttons.

The time differential between two points may be measured if cursor 2 is used. Place the second cursor at the desired measurement point. The time difference between the two cursors will be displayed in the "Time value" box on the right side of the screen.

Identifying Cursor 1 And 2 Display. Scheme 658

Zoom

By selecting the "Zoom" button, a section of the signal pattern may be enlarged to show greater detail. The desired section of the display is called up by touching the screen at the desired spot.

Memory

Memory pages are stored every time the Hold Screen is activated. The DISplus stores the last 10 trigger pulses at the time the screen is held. To recall the memory pages, press the "Memory" button and use the left arrow button to scroll through the previous 9 pages (page 10 is already displayed). The cursor and zoom features may be used on the stored pages.

Preset Measurements

The preset measurements provide an easy method of testing several commonly measured signals. To enter the presets: Press the "Preset measurements" button on the bottom of the screen. A pop up window will provide several signals to choose from. Selecting the signal and pressing the OK button will automatically configure the oscilloscope to the settings needed to provide the best trace pattern. Many tests also have specialized boxes with additional readings( i.e RPM, system voltage).

For instructions on which cables to use for the preset test, follow the instructions in the "Preset measurements" selection of the "Help" menu.

Since the oscilloscope settings are pre-determined, no changes to the oscilloscope are possible.

Identifying Preset Measurements Display. Scheme 659
