I have read all of the FAQ pages and support pages. The detail on the actual ports is non-existent.
PORT A - D1, D0, GND this sounds to me like an RS485 port not a relay. Maybe for Wiegand devices? In which case please answer what can be used on this port? Wiegand fob and keypad would be nice. Otherwise can any part of Port A be used as a relay to open a gate?
PORT B - is this a dry contact? What are its voltage limits? Can it be configured for NO or NC, if not which one is it? Does it momentarily press, or does it press and press again to release, can this be configured in the app? If momentary can the amount of time it is latched be configured? Can it be scheduled to hold the gate open during times of day? Can a user go into the app and open the gate manually and leave it open?
Sorry for all the questions but literally none of this is covered in any manual or web page
