Question 1

will this function as a bus analyzer to support time stamped packet captures? Or is it just buffering data to be read over the usb?

Accepted Answer

It has no internal memory or timestamping. It captures & logs all messages to a simple PC app via USB, but no timestamping just sequential lines of address/data. Also can transmit a single message 1-8 bytes or a script file you prepare with given time intervals, either on the same port or the other port.

Question 2

Is there an updated driver or process to avoid the Windows error message "cannot verify signature"?

Accepted Answer

The current drive on ViewTool website has been certificated by microsoft for window XP,window 7,windows 2000 and old version of windows 10, for updated windows 10, there is no certificate so user has to manually disable windows driver digital certificate

Question 3

Why do I get a failed status when sending data?

Accepted Answer

There are a number of possible reasons ranging from bad wiring to the speed of the communications.  I was getting that message trying to communicate with a STM32 device and I ended up having to modify the data stream pulse widths to better conform with the CAN specs.

Question 4

I installed ginkgo with my device which gives 5 data sets of 64 bits after some time interval. my data at ginkgo is not updating. any guidance here?

Accepted Answer

1. If 5 data sets of 64bits has been presents after Ginkgo driver correctly installed (device led became "green") and no issues reported from Ginkgo apps (I am not sure which software working at this time, supposedly its "Ginkgo USB-CAN Interface Extend Software"), that is abnormal usually, please send us your issue picture with more detail info at our email address: fae@viewtool.com or sales@viewtool.com. Or you can try to more ways on this issue:
1. try another software "Ginkgo USB-CAN Bus Adapter Classic Software" to get more detail info while the error presents, capture the picture can sent to us, refer video demo to get a quick guiance on how to use this software; 
2. get another standard CAN interface device which is proven is right working one to communicate with our can product to see what happends?
3. check the CAN bus payload is correct (see documents on detail on how to connect internal payload for correct hardware wiring connection on can bus protocol communication); 
4. make sure CAN H/L wiring is correct; 
Thanks!
