CAN can be done for under $50 quite easily using the 2011 (and later) KOP and some wise shopping. CAN parts can be made from recycled parts and is pretty easy to wire.
A tutorial on the hardware (electronics) aspect of CAN wiring using the black jaguar out of the 2011 (and later) KOP. Made from the experiences of a veteran wiring student who had no previous knowledge of CAN bus and had to ask a lot of questions and do some experimenting to make CAN work while keeping to a tight budget. Includes previously undocumented (as far as I know of) methods and quick tricks.
Also included is a pinout spreadsheet. If you are trying the “use your own serial cable” method or using an rj-12 adapter with different pinouts than described, feel free to add a new column for your pinouts and delete the ones you are not using. I keep a copy for this exact reason… you never know when it may need to be edited.
Same here. The only time I have ever had to fiddle with DIP switches are when flashing the cRIO.
Edit: Just wanted to point out, make sure that when crimping the cables, the wire ends are fully inserted and have contact with the end of the plug, and you do a FIRM crimp. We did CAN last year, and so many CAN cables failed due to a bad crimp.
The console out switch controls whether or not debug messages and the like are echo’d out the serial port. It has absolutely nothing to do with the network communications link, and as far as I know, should have no effect on the ability to transfer files to the cRio. Perhaps someone else can verify this for me?
Interestingly enough, if you’re using the serial to CAN bridge, I’d think leaving it on WOULD mess with CAN, but I guess if the Jags are smart enough to ignore non-properly formatted messages all it would do is slow things down a bit.
There was an error in the graphics in the latest version.
Since I was using libreoffice and the .doc conversion (when I opened the source to edit it) was to blame for the errors, I now have a .odt version for those who wish to edit using libreoffice/openoffice/etc. the other 2 versions were also updated to fix the error.
Anybody else able to confirm the pinout? Unlike the db9 adapters from mono price these seem to use the correct color/rj12 color scheme. Unless I hear otherwise, I will promptly edit the document to reflect that.
good- all documents have been updated, including the pinout chart
bad- I was only able to upload the .pdf version; the other versions are no longer allowed for upload. I will see if there is a way around the issue, as the editable versions were actually seeing downloads before the filetype ban.
what was changed:
pinout charts updated to include the 2012 pinouts (thank you ggorsuch for the tip!)
changed some image formatting in the serial splice cable section
added references to the 2012 adapter
made some spelling fixes
converted the document to Justified alignment to make it look more professional.
as always, comments and suggestions are always welcome.
EDIT- Weekend/build season wise, today happens to be the 1 year anniversary of the document’s original writing.
