6HC CAN 0 connector

lelynch

I recently purchased a 1LC Toolboard and wanted to connect using the smaller CAN 0 connector on the 6HC v1.02 due to the limited space around the mainboard. I finally found in another post that this was not used for the main CAN bus. What is it used for then? There is no documentation for it that I can find. I'm going to have to do a major re-engineering of my housing to use the RJ-11 connector if I can't use it.

@lelynch you definitely need to use the RJ11 connector.
I believe o-drives use it but its mainly there as a spare to allow another CAN type standard to be implemented

@jay_s_uk Thank you for the information. Guess I have some work ahead of me.

@lelynch it's possible to use the CAN0 connector instead but only if you compile the firmware yourself.

@dc42 Thank you, but that's beyond my current knowledge level and would likely take me longer to learn than just changing and printing new housings to open up this area to the RJ11 port. It would've been helpful to have had something in the documentation that stated that it was for future expansion and that it could not be used for the main CAN bus.

@Herve_Smith I considered it, but wasn't looking to void the warranty since it is fairly new still. It turned out that is wasn't as bad as it seemed and I was able to reprint the housings to add some extra room around the RJ11 connector area.

FYI- these work well, however you do need to trim a bit of the black plastic off around the connector to get it to seat into the 6HC.. which only takes seconds.

@oozeBot Thanks for the suggestion. That's a nice little adapter but would not have helped in this case. I will have to remember it for the future though. I have my problems solved now. It was all a matter of space available on that side of the board. The issue was that the side of the housing that the RJ11 is on only had about 5mm of space to the side of another housing next to it. I wasn't able to make the mainboard housing any smaller but was able to redesign and print the the second housing so it left more room available.
