Hardware Support Questions

[aeitzer]

Hello,

I am trying to confirm hardware compatibility for devices that can measure multiple busses with SavvyCAN.

Can someone confirm if the following devices are supported?

• PCAN USB X6 - https://www.peak-system.com/PCAN-USB-X6.438.0.html?L=1
• Vector CANalyzer products (GL3100 etc.) - https://www.vector.com/int/en/products/products-a-z/hardware/data-logger/gl-logger/#c343633
• CANedge1 - https://www.csselectronics.com/products/can-logger-sd-canedge1

Any help is appreciated. Thanks.

Do you want to use multiple interfaces at the same time?

[aeitzer]

No, we would only be using one of those interfaces at a time, but likely have all of the CAN busses populated for each

I'm currently having an issue with multiple of the these connected in SavvyCAN: https://www.peak-system.com/PCAN-USB-FD.365.0.html?&L=1

Specifically I'm having the issue when bridging them for man-in-the-middle analysis. The vehicle's bus is 500kbit/s at around 25% bus load. I think there is a throughput bottle neck somewhere, but even being USB 2.0 that speed shouldn't be an issue, and if it's a computer processing issue I can't understand why that's causing a hardware (adapter) error/fault. If some forwarded packets were dropped that would probably be ok, but when the LED on the adapter turns red it stops all bridging. I can go into the connections and reset the adapters and it starts working again, but I've never had the bridging work longer than 10sec before one of the adapters turns red.

Any help is appreciated. Thanks.

reads as if the CAN BUS is in the bus-off state. Is the Autorecovery option activated? Typically caused by hardware going through a reset or some kind of hacking prevention?

[ZSC100]

Where/how do I set "Autorecovery Option"?

There is no hacking prevention on the vehicle I don't think the modules simply start working as soon as you connect the CAN wires.

I have seen it work for several seconds, then the adapters blink red, then green, then back red. It's like they are not able to keep up with the packet forwarding, but not sure why the adapters would turn red.

Is there any way for me to see in SavvyCAN what the adapter's errors are when this happens?

Your hardware and QtSerialBus plugin must support this option. I use the RUSOKU TouCAN adapter and CANAL library which support similar functions (windows and macos).They are also added to the RUSOKU QtSerialBus plugin support. All I needed to do was slightly modify the SavvyCAN GUI to add on/off for this options.
IMHO the same can be done with the peakcan QT plugin if these functions are supported by the low level library.
