EVC electronic GmbH -18- BDM100 Module
Interconnections for Siemens MSS65 ECUs
Pict.A: The main connector of the MSS65 ECU.
On the Siemens MS45 ECU the power
distribution is provided by the pins of the
main connector as shown in picture 19a.
Use separate wires to connect GND and
+12Vcc to the pins of the main connector
shown in picture A.
On the MSS65 board there are two
processors which each own programming
port pad arrays. Each array consist of 30
pads but only the first 10 of them are used
for BDM purposes.
For connecting the BDM-pads controllable
the BDM141 and also the BDM144 probe
are required.
Now place the BDM probes in succession
into the positioning frame and carefully put
the tips of the spring contact probes on the
pads on the board as shown in picture B
and picture C.
If the length of the spring contact pins
should be to short, pull the spring contact
pins up to the first rest position from the
receptacles.
The tips of the spring contact probes should
reach a spring travel of 1mm minimum for
best contact conditions.
If you then applying power to the main
connector of the ECU the red LED of the
BDM14x probe lights up to indicate that the
logic on the board is supplied with the
required voltage
The BDM100 module is now operational
Pict . B: On the MSS65 board both the BDM144
(shown in this picture) and the BDM141 probes are
required.
Pict . C: The BDM141 probe contacting the BDM-
pads of the second processor..
