Uses an EIA-485 (RS-485) physical interface over a twisted, shielded wire pair (TSP).
The APC loop maintains constant optical power by adjusting the drive current, compensating for temperature-induced efficiency drops. VLC 1600 datasheet, optical output power, forward current,
Before diving into pinouts and absolute maximum ratings, it is crucial to identify which you are dealing with. Based on market research and technical forums, the two most common interpretations are:
