Unsure about CAN Jaguar Errors

[otherguy]

The youtube video you linked is mine.

The wiring for the connector from NI and in the video should (and need to be identical). The colors NI lists in the document don't match, but you shouldn't wire by color. I mention this in the video, the wires within the DB9 connectors are not always consistently colored. There is a standard convention, but not all manufacturers seem to adhere to it.

There's a comprehensive writeup of how to make the cables and flash the jaguars on my team's website here: http://team2168.org/index.php/resour...10-can-jaguars

Verify your cable is made correctly with a multimeter to check continuity to the pins listed on the website. Use a paperclip to probe the pins in the DB9 conenctor, and the tip of the meter should be able to probe the pin on the RJ12 connector.


All that said, I would first verify that the USB to serial adapter you have is actually working. There's a lot of crappy USB to serial adapters out there, and a lot of them don't actually work with newer versions of windows.

A quick way to check is to plug in the adapter, open up a serial application (like putty). Bridge the transmit and receive wires on the DB9 side of the serial connection. Anything you type in the terminal program should show up printed on the screen. If it doesn't, then you have a problem with your USB->Serial adapter that needs to be addressed before you can start tying to get anything else working.

If you need more help let me know what you need clarification/guidance with.

[edit] It also may be worth noting that in the upcoming season, you will no longer need to communicate to the Jaguars through the serial bridge to a black jaguar. The new roboRIO has built in support for the CAN bus. See more information here.
