Oh, nice! The left-hand LEDs on these RJ-45 connectors are bi-colour (green/yellow):

Here's a little RS-485 test board to check the footprint and the interface circuitry. I'll wire this up to a Pi Pico, then if everything tests out, I'll make a #Protonema stamp for it.

Pretty standard on 10/100 ports.

Indeed!

I'm going to be using these for RS-485, with the RED LED indicating termination, green indicating RX, and yellow indicating TX.

I usually use 3 or 5 pin XLR for RS485, something about spending too much time doing lighting.

All the renewable energy control equipment I'm working with uses RJ-45. Other equipment I've used was based around Phoenix terminal blocks. Seems to largely industry-by-industry conventions.

Aye, I've seen D9 used a lot too.

@ve7fim @zl2tod so one could read the leds from a distance to decode what’s going on (there’s a paper on that)

I don't connect TX/RX directly the LEDs, but rather drive it from the software stack. That way you can have more control over the blink behaviour and it doesn't leak nearly as much information.
