DIY VE.Can terminators

I might need to use some ve.can gear soon and I'll need terminators, but I really can't find them anywhere (USA). Does anyone know what the terminators consist of so that maybe I can just make my own?

120ohm resistor connected in parallel on the bus, nearbuy at the end of the line at the latest device

What pins of the rj45 would that be?

In a pinch, this works fine.

There are good answers here for the DIY route.

They come supplied with every GX device, and many systems do not use VE.Can functionality, so dealers tend to end up with a few.

It is also possible to purchase them under Victron part number - ASS030700000

I would make polite enquiries with Victron Dealers in your area, they might have some spares.

Fyi the Octo-GX I've received recently did not come with one. Hence my hack.

2x 120 Ohm between CAN-H and CAN-L on both bus ends

Beware there must be no more than 2 (two) terminators in the whole CAN network, one on each network endpoint.

The network (bus) without powered devices should measure about 60Ohm between CAN-H and CAN-L
