DB25 Switch/LED Connector
We're new. Sorry if this question has already been asked.
BrightSign HD600 documentation says "Connect LED outputs to the LED CATHODE and connect LED ANODE to ground." Schematic on next page shows the opposite (and what would be reasonably expected).
Which is correct?
Also, "...output is capable of sourcing or sinking up to 24ma at 3.3v..." are LED outputs truly either active high (source) or low (sink)? If so, how do you specify which you want? If not, which are they, sink or source?
