1.5 MAKING A CONNECTION BETWEEN ECU (ENGINE) AND NOTEBOOK
• Serial communication
• Baud rate = 9600
• Serial port = COM1
An interface forming part of the SERDIA scope of delivery serves as a link between the ECU and the notebook. Despite a
large number of safety measures in the interface and the ECU, such as protection against incorrect polarity, surge voltage
protection and decoupling, the possibility of errors can never be entirely excluded.
For this reason, the connection should be made by adhering closely to the following sequence:
1 - Switch off engine, turn off ignition switch (terminal). Do not switch on the notebook yet.
2 - Plug the diagnostics plug on the interface into the diagnostics socket on the vehicle/equipment.
3 - Connect the other interface side with serial interface RS 232/COM1 . (9 pole plug at the back of your
noteback).
ATTENTION!
On PCs, the COM1 interface may sometimes be occupied by the mouse. If this is the case, you should
connect the interface to the second serial interface (COM2). This must then be configured (see Chapter
8, What should you do if...?).
4 - You can now switch on the ignition (terminal 1 5) and the notebook. For the time being, do not switch on the engine.
5 - You can now start the program SERDIA in accordance with the instructions given in Chapter 1.6 Program start.
1.6 PROGRAM START
Call the program SERDIA under Windows by double clicking.
SERDIA starts up with a main screen and a sub-screen "ECU selection". In this screen, you can only select "OK", "Cancel"
or "Help".
