2 Preparation
Use the DDU 10 only as intended in this manual. Any maintenance or repair must be per-
formed by authorized and qualified personnel approved by Bosch Motorsport.
Operation of the DDU 10 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 determined 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.
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.
NOTICE
In this document, all screenshots are created by way of example for a
display. Please consider this and replace the product names with the
name of your device.

Power Supply | 3
Bosch Motorsport DDU 10 7/188
3 Power Supply
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 Starting up
4.1 Before starting
Install the software required for the operation of the DDU 10 . It is developed for Windows
system software. The following software versions are used in this manual:
– DDU 10 setup, configuration and calibration: RaceCon Version 2.6.
– Measurement data analysis: WinDarab V7
Set up the 100 Mbit ethernet connection to the DDU 10.
– The ethernet port has “cable auto crossover” functionality
4.1.1 Starting the unit
The DDU 10 powers up by turning on the ignition of the car. At startup the DDU 10 will
display a Bosch logo.
After a moment the DDU 10 shows a display element screen.
4.1.2 Connecting the unit to RaceCon
For testing new device configurations, you can connect the device to your computer via
MSA-Box or ethernet cable.
Connection via MSA-Box
1. Reassure that the MSA-Box is installed properly on your computer. If needed, down-
load the MSA-Box Diver from www.bosch-motorsport.com.
2. Connect an ethernet line of the device to the ethernet line of the MSA-Box.
Please note, that the MSA-Box also requires power supply on the MSA-Box connector
of your wiring loom.
3. Open RaceCon and connect the MSA-Box to the computer.
In the ‘Info / Status’ Box of RaceCon you will receive messages that the connection
was successful.
4. Reassure that the device is switched on.
5. ‘Link LED’ at the computer’s network adapter will illuminate.
If the LED is off, check the wiring harness.
After you created a RaceCon project with the device, the status icon of the device will
switch from grey to one of the following colors: red, orange, green. For further in-
formation on how to set up a project, see the chapter “Setting up a new RaceCon Pro-
ject [}9]”. For the status color, see chapter “Color indication [}22]”.

Connection via Ethernet Cable
1. Follow the steps above for a connection via MSA-Box.
2. Instead of connecting the ethernet line to the MSA-Box, Connect the ethernet directly
to your computer.
Troubleshooting while setting up the network interface
The DDU 10 contains a DHCP server, network addresses can be assigned automatically to
the configuration PC. In case of problems during the network connection, please try the
following steps:
1. Switch off the PC’s firewall.
2. Reconfigure the PC or the MSA-Box network interface settings, to obtain an IP ad-
dress automatically as shown in the pictures below.
Select
'Internet Protocol
(TCP/IP)'
Click
'Properties'
Select 'Obtain
an IP adress
automatically'
Click 'OK'
when done
