Technical manual for Multifunction Vehicle Bus Electrical Short Distance Module MVB2791B.
1.1 Warning symbols used in EKE manuals
In EKE manuals, situations that require caution are marked with special warning symbols. The warning symbols appear
in the beginning of the appropriate chapter or paragraph. The following symbols are used.
Table 1: Warning symbols
Symbol Description
Electric shock warning symbol
Laser warning symbol
Hot surface warning symbol
ESD warning symbol
General caution symbol
Note symbol
Separate collection for Waste Electrical and Electronic Equipment according to Directive 2002/96/EC
(WEEE)
1.2 Safety considerations
The module is a low voltage device. In a normal situation, it presents no safety risk to the user.
Electric shock warning:
In the case of a severe train malfunction or wiring errors, there is a risk of an electric shock through connection
cables.
Electric shock warning:
The module contains components with large capacitance, and can hold voltage charge for one minute.
CAUTION:
The rack and modules can contain sharp edges. Use protective clothing, such as gloves.
CAUTION:
The protection components on the module are intended to protect the module from external surges and
transients only. They do not provide protection against incorrect wiring or connection.

CAUTION:
In a warm environment, some components may become very hot. This does not harm the module, but it could
harm you. Touching hot components may cause burning of skin. Carefully hold the module by the front panel or
sides, and DO NOT TOUCH ANY COMPONENTS.
1.3 Correct handling of the module
Electrostatic discharge (ESD) can damage electronic circuits. EKE products are protected against ESD. However, you
run the risk of delivering electrostatic discharges to the module whenever you handle it or any of its components.
To avoid this risk, only handle the module at a static-free workstation. If this is not possible, you must ground yourself
using a wrist strap and a resistive connection cord. Remember to handle the module according to these instructions,
even when you are removing a defective module, and sending it to the service.
CAUTION:
When you install, remove or handle a module, always hold it by the front panel or the sides. Do not touch the
components.
1.4 Ambient conditions for storage
The table below lists the ambient conditions for storage, for the products.
Note:
These are general conditions. You can find product specific conditions (if any) in product documentation.

documentation, such as application notes, optional parts, or accessories, the references are included as separate
chapters in the documentation.
Important:
This manual does not include information on other EKE-Trainnet® products than the MVB module. If you need
information about other EKE-Trainnet® products (such as modules, racks or accessories), refer to the manual of
the product in question.
The module type is also the ordering code.
This chapter includes general information about this manual.

3 Module features and operation
This chapter contains information on the module features and operation.
3.1 Module identification
The figure below shows where to find the version and the modification information.
Figure 1: The location of version and modification information
Located on the back connector, the modification label indicates the module modification. The label has letters, and the
modification is indicated by crossing out one. If letter A is crossed out, the modification is A, and so on. If nothing is
crossed out, modification is 0 (that is, no modifications). This modification field is for the entire module.
The circuit board may have a different modification level, indicated by numbers printed on the board’s modification
field. This is found on the back side of the circuit board.
The Board test label indicates that the module has gone through the required testing cycle. It is located above the
board modification field.
The Board serial number identifies the module. It is located above the board test label.
The Board ID next to the board test label indicates an ID for the circuit board.
The Module ID, located just below the front connector, indicates an ID for the entire module.
Manufacturer's name
The manufacturer's name is EKE-Electronics Ltd.

3.2 Functional block diagram
The figure below presents a general functionality diagram of the MVB module.
Figure 2: Functionality diagram of the MVB module
The module has a fully IEC 61375-3-1 compliant redundant Multifunction Vehicle Bus interface with Electrical Short
Distance Media (ESD) with galvanic isolation. The maximum bus cable length for MVB ESD is 20 metres.
The MVB module is designed to ensure reliable data transmission on board a train. The following sections present
some MVB features intended for this purpose.
3.3 CPU
The local CPU MPC8306 combines a high-performance CPU core with a variety of resources useful in a broad range of
applications.
3.4 Duplicated line
To ensure uninterrupted functionality of the Multifunction Vehicle Bus, the bus is duplicated: there are two lines (A and
B), through which devices transmit data. If one line is temporarily out of order, the other line can take over, and full
redundancy is ensured. In this way, the flow of important data can continue without interruption, even in the case of
potential problems.
3.5 Shared memory
The MVB module configuration is done through the Gateway CPU, and the MVB reads it through its shared memory at
the start-up of the system. The configuration is for the MVB module read-only, and it is managed by the CPU software.
If any changes are made through the debug terminal, the original configuration is retained when the module is reset.
The module has a Medium Attachment unit (MAU) with a MVB FPGA, which supports internally the ESD interface.

4.1 Warnings
This section contains warnings you need to consider before and during the module installation.
CAUTION:
Do not turn on the rack power, before you have finished the installation of the modules.
Never remove a module from a rack with active power, as this can damage the installed module or other
modules in the system. Always switch OFF the rack power first BEFORE removing the rack.
ESD warning:
When handling the module, only touch the front panel. Do not touch the board or any of the components on it.
Even when you are removing a defective module and sending it to maintenance, handle the module according
to these instructions.
CAUTION:
Make sure that the module or any of the components on it do not get wet
The module has no implosion or explosion hazards in use or in handling.
ESD warning:
Electrostatic discharge can damage electronic circuits. Always handle the module at a static-free workstation. If
this is not possible, ground yourself using a wrist strap and a resistive connection cord.

CAUTION:
The module and rack can contain sharp edges. Use protective clothing, such as gloves.
Do not drop the module.
CAUTION:
If your module contains M12 X-coded connectors, pay special attention when plugging them. This connector
type is easily broken due to bent pins. The type test setup has shown that plugging M12 X-coded connectors
with force, or turning/twisting the connector to find the correct orientation, will cause problems, which are
directly or indirectly identified later.

4.2 Installation procedure
This section describes how to install the hardware.
Before you start installing the module to a rack:
• Make sure you have a Pozidriv® Pz0 or Pz1 screwdriver to tighten the front panel fastening screws on the module.
• Check the shipping container to see that it is not damaged.
• Take the module out of its shipping container carefully. The module is always shipped in an ESD protective
wrapping.
• Check the module, especially the connectors, for any visible signs of damage that may have occurred during
shipping.
Install the MVB module in a VME or VME/IO slot on the rack.
Figure 3: Modules installed in a rack
Proceed as follows:
1. Hold the module by the front plate.
2. Place the module on the rails of the rack.
3. Slide the module towards the back plane of the rack until it clicks into its place.
