I have an E6C PID controller - Looking at pins 4,5 &6 , they are labelled o/p3 and have RS485 next to them. Does this mean they could be used to acquire data, if so, what data, and how?
Never used one of those, I've had enough problems with cheap converters over the years. Although more expensive, I prefer Brainboxes stuff. The Uc 324 is what I use at the moment.
So far I've only used then as 4-wire but in a fortnight I'll be trying a bus with some of these on so I'll have to go back to the bad old days of 2 wire.
