MOTEC SDL with AUTRONIC SM4 1.09

Postby bazeng on Sun Nov 01, 2009 10:31 am

Hi Guys,

I have an AUTRONIC SM4 and will be using a MOTEC SDL to log / monitor the engine.

I have all the wiring diagrams etc and just needed confirmation with the wiring.

I am assuming

AUTRONIC______________|____________________MOTEC
SM4 1.09_______________|____________________SDL

RS232 RX - pin 5 (db9)___|____________________TX/TELEM - pin33
RS232 TX - pin 2 (db9)____|____________________RX - pin 34

Is this correct?
I could only find the AUTRONIC pinouts from the AIM DASH documentation.
The SM4's use a stereo jack loom which converts it out to a db9 connector hence the db9 pinouts.

Thanks in advance.

With an Autronic SM4, you need to hook up 2 wires.

You connect the Pin 2 on the Autronic D9 (TX) to pin 34 on the SDL (RX).
You also need to hook up pin 5 (which I believe you will find is Ground, not RX)to Pin 37 (0v)

Not absolutely sure about the 0v, when I last did this, I believe that the SM4 wont transmit without the 0v connected, I don't know why.

Perhaps try just connecting the SM4 Tx to the SDL Rx, and see how that goes. If it doesn't work, hook up the 0v...

Thanks Jamie,

I will let you know how it goes.

My mistake Jamie.

The AIM install details I have are somewhat corrupt and the text is all over the place.

Pin 5 is actually is the gnd on the SM4 DB9 side, not RX.

So it should be:


AUTRONIC______________|____________________MOTEC
SM4 1.09_______________|____________________SDL

RS232 GND - pin 5 (db9)___|___________________GND - Pin 37 (0v)
RS232 TX - pin 2 (db9)____|____________________RX - pin 34

Hi guys,

Just a quick question.

How do I obtain the values from the SM4?

I'm assuming its from the Channel:

DATASTREAMS
OR
ECU - Generated Channels

Now,
DATASTREAMS contains JI587
and
ECU - Generaged Channels contains a bunch more values but doesn't contain (MAP or BOOST)

Where can I obtain all my ECU generated values?

I have already enabled the SM4 input by:
->INPUTS
-> Communications
-> RS232
-> Autronic SM4

Thank you!

Ok,

I connected it up.

I just used the unused channels button to find the required channels.

Seems to be working fine!

Pins 2 & 9 on the DB9 connector are good.

Thanks for the help Jamie
