Connection of the plugs
To operate your MFD15 Gen2 via the Can bus, only four wires are required:
•
12 volts on-board voltage, ideally ignition plus -
>
Pin B5
•
Ground
->
Pin B6
•
Can High (
CanH
)
->
Pin C7
•
Can Low (
CanL
)
->
Pin C8
The wires of
CanH
and
CanL
should always be designed as twisted pairs in order to minimize
interference signals.
Figure 1: MFD15 Gen2 Pinout
Of course,
CanH
and
CanL
are not necessarily necessary for operation. Via the six analog inputs (
AIN
s
–
analog inputs) you can also feed the 0-5 volt voltages of analog sensors into the display and have
them converted by the display and monitored on it.
By default, four of the
AIN
s are preconfigured for different sensors:
•
AIN
1: Oil temperature (
OilT
)
->
Pin C2
•
AIN
2: Exhaust gas temperature (
EGT
)
->
Pin C3
•
AIN
3: Oil pressure (
OilP
)
->
Pin C4
•
AIN
4: Boost (
MAP
)
->
Pin C5
The analog inputs five (pin C9) and six (pin C10) are not preconfigured.
