1 Preparation
Use the VCU MS 50.4P only as intended in this manual. Any maintenance or repair must
be performed by authorized and qualified personnel approved by Bosch Motorsport.
Operation of the VCU MS 50.4P is only certified with the combinations and accessories
that are specified in this manual. The use of variant combinations, accessories and other
devices outside the scope of this manual are only permitted when they have been de-
termined to be compliant from a performance and safety standpoint by a representative
from Bosch Motorsport.
Read the manual carefully and follow the application hints step by step. Do not hesitate to
contact us, contact data can be found on the last page of this document.
Important information on Electromagnetic Conformity
To avoid unwanted interference with the environment (people, animals, electronic devices)
or unwanted harm to the environment, it is mandatory that the user of the VCU MS 50.4P
carries out an appropriate analysis to determine the electromagnetic interaction the VCU
MS 50.4P may have with its individual installation environment.
Disclaimer
Due to continuous enhancements, we reserve the rights to change any illustrations, pho-
tos and technical data within this manual.
Please retain this manual for your records.

3 Onboard Network Concept
Please ensure that you have a good ground installation. That means:
– A ground that has a solid, low resistance connection to the negative battery terminal
– Connection should be free from dirt, grease, paint, anodizing, etc.
– Use large diameter wire
– More metal-to-metal contact is better!
The following notations for power signals are used:
– KL 15 is a switched battery rail controlled by the IGN-switch
– KL 30 is an unswitched battery positive rail (same as battery positive terminal)
– KL 31 is an unswitched ground rail (same as battery negative terminal)
Be careful to observe current limits of wires and connector pins!

4 Technical Data
The VCU MS 50.4P (Performance) is a highly powerful processing / logging unit for race
applications.
Based on our broad base of platform function, we support you with customized VCU func-
tions for a tailor-made solution.
In addition, you can quickly develop your individual customer software based on MAT-
LAB/Simulink to significantly speed up algorithm development (automatic code and docu-
mentation generation, requires CCA package) – including extensive simulation capabilities.
The device offers real time Ethernet functionality to exchange e.g. data used in control al-
gorithms between devices (guaranteed latency time 1 ms).

Upgrade High Speed Logging Package
6 ANA 0 to 5 V, 200 kHz logging rate
Upgrade CCP Master
Enables CCP master functionality to request data from foreign devices via CAN/CCP pro-
tocol.
Upgrade Real Time Ethernet
Enables the VCU to operate as a real time Ethernet master or slave. Guaranteed latency
time of 1ms. Ideal for time critical data transfer as needed in online control algorithms
involving data from different devices.
Two interfaces allow for a ring topology (redundancy in case the RTE line experiences
damage).
The VCU features a reasonable set of SERCOS3 instructions although not the full SER-
COS3 standard is implemented. The ECU side can act as a SERCOS3 master; the logger
side can act as a SERCOS3 slave.

6 Communication Channels
CAN bus
The VCU MS 50.4P has two CAN buses configurable as input and output. Different baud
rates are selectable. Please note that the VCU MS 50.4P does not contain any CAN termin-
ation resistors. Thus, the CAN termination resistors need to be integrated into the wiring
loom.
Ethernet channels
The VCU MS 50.4P has three 100 MBit full duplex Ethernet communication ports. The
ports are internally connected with an Ethernet switch. The Ethernet ports have 'cable auto
crossover' functionality.
RS232 port
The VCU MS 50.4P has one RS232 serial port dedicated to inbound GPS data.
Vehicle diagnosis connector
The Bosch Motorsport vehicle diagnosis connector is used as a standard interface to con-
nect the vehicle to a PC e.g. via a MSA-Box II. Loom connector: AS012-35SN

8 Starting Up
Install the software required for the VCU MS 50.4P operation. It is developed for Windows
system software. Following software versions are used in this manual:
– VCU MS 50.4P setup, configuration and calibration: RaceCon
– Measurement data analysis: WinDarab
Set up the 100 Mbit Ethernet connection to the VCU MS 50.4P.
– The Ethernet port has ‘cable auto crossover’ functionality.
8.1 Setting up a new RaceCon Project
The following screenshot shows an overview of the RaceCon Main Screen with its areas.
All (sub-) windows are resizable and dockable. You can find them under the ‘Windows’
tab.

2. In the ‘File’ menu select ‘New project’ to create a new project.
Note: The VCU MS 50.4P is represented in RaceCon by two symbols: VCU-Logger and
VCU-ECU.
3. Unlike other Bosch Motorsport devices, the VCU MS 50.4P needs two different pro-
gram archives – the Logger program archive and the ECU program archive.
For the Logger program archive, go to the Toolbox and select the VCU MS 50.4P.
Drag it into the Main Area. A pop up window appears, to specify the VCU MS 50.4P
Logger program archive.

4. In the next step, the ECU needs to be specified.
A pop up window appears, to specify the ECU program archive.
5. Download the firmware for the VCU MS 50.4P from www.bosch-motorsport.com.
An information shows if the archive is valid or not.
6. Click ‘Next’.
