SOLVED - Could use some help commissioning a tool board

deckingman

I've just applied power to my new build for the first time and can't get CAN sync on the tool board. I have a 6HC main board and single tool board v1.3 (no distribution board). The sync light on the 6HC is flashing normally at about 1Hz but the sync LED on the tool board is flashing rapidly and continuously. The blue Vin LED is lit as is the red 5V LED. Following the documentation, I think I've done everything that I should. I've bridged the solder joint to bring the 120R termination resistor into play. I used a Kenable high speed ADSL cable (two twisted pair) and cut off one of the RJ11 connectors. As per the wiring instructions, I used the twisted pair connected to the centre pins of the RJ11 and connected RJ11 pin 4 to Can L pin3 of the supplied jst zh and RJ11 pin3 to Can H pin4 of the jst. At least I'm 90% sure that's what I've done but there is a 10% chance that these might be reversed depending on how one views the RJ11 when identifying pins. Would that matter?

Anyway, I've checked continuity from plug to plug and that's all fine.

I tried holding both buttons on the tool board while applying power to do a factory reset to no avail.

I'm a bit stuck now.............

Edit. Oh and I do have a G4 delay in my config.g before any CAN related commands.

@deckingman try swapping the two conductors over. It doesn't damage anything if you get them the wrong way round. One way to swap them is to use fine tweezers to remove the crimps from the ZH connector and re-insert them the other way round.

Thanks David- that fixed it!

@droftarts For future reference, it might be worth mentioning this in the CAN troubleshooting section of the docs or in the tool board connection section. Also for reference, I discovered that if you gentry prize up the "tang" on the jst zh shell with a very fine screw driver ( a pin or fine needle would also work), the connectors easily slide out.
