@uint8_t canbus is only two wires, right? why not 4p2c or something
Show threadZ̈oéNov 7, 2019

@ellies it needs two wires only, but shielding does not hurt
we would need tooling for 4p2c (rj11) and have everything for 8p8c plus a half spool of Cat5e

Elen would like to avoid the (although non-catastrophic) possibility of swapping our 1GBase-T and CAN-FD wiring

I though color coding will do

@eqe @uint8_t kinda cursed. Type2 connector doesn't use CAN but only resistance encoded current limits.

@dwagenk @uint8_t the only connector that's really worth my time is the CBM meeting specification S683-29902

@uint8_t from what I encountered the DB9 is common. Easy to hook up a USB2CAN adapter for debugging the bus.

@uint8_t what about XLR? Or Schuko, except cables have plugs on both ends. 😬

@uint8_t NBD over USB over WiFI has to be my favorite, but DSL over wet shoestring comes close

@uint8_t 8p8c/RJ45 because the patch panels and cables are so ubiquitous and cheap. I crimp those on a lot of different cables (this week I made myself a MIDI extension cord that way).

CANL/CANH should be one of the pairs, crimp shield on one of of the spare pins, but be consistent.

Use pachpanels with the wires crossing many sockets as a bus/splitter/...
