There will be another in the future, so don't hesitate to reach out.

Hello frodus, any update on delivery dates?

Thanks
Giacomo

I've been emailing everyone in the group as I get updates from my suppliers:

The harnesses are being built locally, we're due to confirm pin-out and assembly this weekend. The IXXAT cables arived today. The other items (motors, controllers, chargers, BMS) are on a freight shipment as we speak and are due to arrive late this week.

I can try to ship the IXXAT for you first, since you did not order anything else and it is the only item I've got currently.

Other items depend on when I receive my freight shipment, but should start the first week of January. Those that ordered items that do require programming (DeltaQ and Sevcon) will be done 1 by 1 in the order which they were paid.

Hello,

Does anyone knows where to buy DB9 to ODBII cable compatible with IXXAT USB-to_CAN / Zero?

Thanks,
Giacomo

No. The pinout of a standard DB9 to OBDII cable isn't the same DB9 connections on the IXXAT. You'd have to make one.

I'd get this and cut the end off:
https://www.amazon.com/Docooler-Obd-ii-Extension-Diagnostic-Extender/dp/B000SBCHCA

and this:

Thanks,

Do you have the ODBII <-> DB9 pin to pin connection table?

I have found this cable already premade but I am not sure if it will work:

ODBII Pin#     <---->      DB9 Pin#
      4                                 6            (chassis ground)
      5                                 3 & 5      (Signal ground)
      6                                 7            CAN BUS High
     14                                2            CAN BUS LOW
     16                                9            Power

Thanks,
Giacomo

You'd have to locate the OBDII pinout or the Zero pinout if it's nonstandard. There's 2 CAN busses on the OBDII connector.


IXXAT:
https://www.ixxat.com/docs/librariesprovider8/default-document-library/products/can-pc-interfaces/usb-to-can-v2-manual-english.pdf?sfvrsn=2
Pin 7 is CANH
Pin 2 is CANL
Pin 3 or 6 is signal ground

OBDII Pinout is an industry standard:
https://en.wikipedia.org/wiki/On-board_diagnostics
Pin 6 is CAN H
Pin 14 is CANL
Pin 5 is Signal Ground


So:
ODBII Pin#     <---->      DB9 Pin#
      5                                 3 OR 6      (Signal ground)
      6                                 7            CAN BUS High
     14                                2            CAN BUS LOW


Don't connect power or chassis ground. Also, your original pinout stated 3 & 5 for signal ground. it's actually pins 3 & 6 according to IXXAT.

There's a lot of  "manufacturers discretion" in those ODBII pin numbers. I believe pin 11 is CAN ground on the Zero. Pin 5 is signal ground for the UART serial on pins 8 and 9. Pin 5 might work for CAN bus too since it is differential.
