ConCan Wiring Documentation Wrong

toernblom · Post by **toernblom** » 09 Nov 2021, 17:28

Hey, on my physical ConCan module it says CAN_H on pin3, yet the documentation on https://revolutionpi.com/tutorials/uebe ... chliessen/
says CAN_H on pin2. Which one is it? I've already connected according to my physical device which has the indication on the side but I'm not getting any data from that and not sure if it would mess something up to change the polarity of the CAN bus so I'd rather wait for an answer.

Hi,

thanks for letting us know that the pinout in our documentation is not consitent. I checked with our schematics and the pinout is the following:

Pin Assignment
1 Resistor 60 Ω
2 CAN_L
3 CAN_H
4 Resistor 60 Ω

We will change table in our documentation.

Perfect! Thanks.

You were actually wrong. I switched the connections and use CAN_H on Pin2 and now it works well.
So the printed label on the physical Con Can is wrong, which currently is labeled CAN_L on pin 2.

I followed this 8 month old post which already pointed it out

My apologies! I will clarify with the team and make sure this is addressed the right way.

Hi Anton,

can you please share a photo of your module with the serial and the connector X2?

No worries. Yes! Attaching here.

Thanks for the photo. Could you please also share the serial (located on the front, second row next to the data matrix code).
