Hi, is it correct that R8 is the CAN termination resistor on the MS3? I am asking before I remove it...
regards, Thomas

Re: R8 on the daughterboard
That looks correct but it would be better to have a confirmation from a developer. However, why do you want to remove it from the MS3? I assume you have more than one CAN device on the bus you're using but that seems like the wrong place to remove the termination resistor. The ECU will always be on the bus so it should be one of the end points.

Re: R8 on the daughterboard
I actually came across a bike where there was a simple 125KBps bus, ECU <-> ABS. Neither of them had a termination resistor but there were probably closer than 30cm away, wiring-wise. In this case, the termination resistor on the MS3 daughterboard prevented communication between the MS3 and the ABS unit (the stock ECU was removed). As soon as I removed the resistor, comms were restored.

That is strange and it definitely is not compliant with the CAN bus standards.Reverant wrote:I actually came across a bike where there was a simple 125KBps bus, ECU <-> ABS.

Re: R8 on the daughterboard
I have got multiple devices indeed. I have got an ECUmaster PMU on one end with termination activated and then an ECUmaster keyboard, an 8fold EGT module (ecumaster), a racetechnology dash+ datalogger, a steeringwheel module (ecumaster), and at the very other end a analog board for diff and gearbox temps with termination again. Wiring loom wise this does simply not work with the termination inside ms3...
