The extra 120Ω on the CAN transceiver is unbalancing the termination. 1(1/120Ω ) = 120Ω ; Needs one. 1(1/120Ω + 1/120Ω ) = 60...

Re: Vida CEM swapping

Hi, no just in position II. Should i try it in Position 0? Latency is not different for lets say 5 positions. There is no clear favorite, there are some: Example: 17:11:18.712 -> best candidates ordered by latency: 17:11:18.712 -> 0: 43 lat = 210001 17:11:18.712 -> 1: 95 lat = 210000 17:11:18.712 ->...
