1: General information
This chapter includes general information about this manual (MVB EMD Multifunction
Vehicle Bus Module Technical Manual).
The following topics are covered in this chapter:
About this manual
Safety considerations
Correct handling of this module
Warning symbols used in this manual
1.1 About this manual
This is the technical manual for the EKE-Trainnet®MVB Multifunction Vehicle Bus
module.
In this manual, the abbreviation MVB always refers to the module, not to
the MVB bus. The module is referred to as “the MVB module” or "MVB".
When talking about the Multifunction Vehicle Bus, the entire name is used.
This manual includes instructions for the following tasks:
Installing the MVB into a rack
Troubleshooting the MVB on board
Troubleshooting the MVB with software
Note that this manual does not include instructions for the installation or maintenance
of the rack or its components. For these instructions, refer to the manual provided by
the rack manufacturer.
Also, this manual does not include information on other EKE-Trainnet®products. If you
need to check other modules than the MVB during troubleshooting, refer to the manual
of the corresponding module.
1.2 Safety considerations
The MVB is a low voltage device. In a normal situation, it presents no safety risk to the
user. However, in case of a severe train malfunction or wiring errors, there is a risk of
an electric shock through the bus cables.
General information
2
When you remove and handle a module, always hold it by the sides. Do not touch the
components.
Never disconnect the MVB from, or connect it to, a rack with active power, as this can
damage the MVB module or other modules in the system.
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 MVB 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 maintenance.
1.4 Warning symbols used in this manual
In this manual, situations that require caution (as specified above) are marked with
special warning symbols. The warning symbols appear in the beginning of the
appropriate chapter. The following symbols are used.

2: Overview of the MVB
module
This chapter lists selected specifications of the EKE-Trainnet®MVB module and
highlights some of its features.
The following topics are covered in this chapter:
Selected specifications
Module identification
Functionality diagram
MVB features
2.1 Selected specifications
The EKE-Trainnet®MVB module is designed for train data transmission. It is an
interface between the VME Bus and devices attached to the Multifunction Vehicle Bus.

2.2 Module identification
Version and modification information appears on the board. The following pictures
show you where to find this information.
Figure 2.1: Location of version and modification information
The modification label shows the module modification. It is located above the back
connector of the module. The label includes letters, and the modification is indicated by
crossing out one. If nothing is crossed out, the modification is 00. If the letter A is
crossed out, the modification is A, and so on. This label gives the modification level of
the entire module, and the circuit board may have a different modification level,
indicated by numbers printed on the board’s modification field.

The board test label indicates that the board has gone through the required testing
cycle.
The serial number identifies the module. It is found on the back side of the front panel.
This is the serial number of the entire module, and the board has its own serial number.
The Module ID, located on the front panel handle, indicates an ID for this module. Again
note that the board has its own Board ID.
2.3 Functionality diagram
The following figure presents a general diagram of the MVB module functionality. For
a more detailed block diagram, see Appendix B.
Figure 2.1: General functionality diagram
2.4 MVB features
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.
2.4.1 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. In case
one of the lines is temporarily out of order, the other line can take over, and full
redundancy is ensured. This way, the flow of important data can continue without
interruption even in case of potential problems.

2.4.2 Medium Attachment Unit
The module has a fully IEC 61375-1 compliant redundant Multifunction Vehicle Bus
interface with EMD (Electrical Middle Distance) media, isolated by transformers.
The implementation of redundancy is based on MVBC01 ASIC and is subject to its
limitations.
EKE-Electronics LTD also manufactures versions of the MVB module, which support
OGF (Optical Glass Fibre) or ESD (Electrical Short Distance) media.
