Connection of the plugs
To operate your MCE18, only four wires are needed:
•
12 volt on-board voltage, ideally ignition plus
-> Pin 1
•
Vehicle Mass
-> Pin 2
•
Can High (
CanH
)
-> Pin 26
•
Can Low (
CanL
)
-> Pin 27
The wires of
CanH
and
CanL
always act as twisted wires in order to minimize interfering signals.

ATTENTION: some MCE18
version 1 have mounted the
connector partially twisted
by 180 degrees, here the
release tab points
downwards.
The pinout is to be read as if
the tab were up.

The MCE18 has analog inputs (
AIN
–
analog input), digital inputs (
DIN
–
digital input) and digital
outputs (
AUX
–
auxiliary output). The inputs are placed on the Can bus as 0-1023 ADC values. An
internal mapping of the values has not yet been implemented.
The power supply to operate the analog sensors can also be realized directly via the MCE18. During
operation, 5V is applied to the corresponding pins, and you can obtain the sensor ground via the "S-
GND". The maximum current of 0.5 amps should not be exceeded.
