Helixnet: What are the functions of Pin 2 & 3 of HelixNet Powerline
Question: Pins2 & 3 both carry DC volts. From some tests that we have done, I havenoticed that there is still some 'power' (the buttons are backlit) when pin 2is disengaged. Hence, would I be right in observing that to a degree that aspin 2 is the positive DC volts, this 'carries' data transmission to belt packsand pin 3 does belt pack to main station?
Answer: Itis a full duplex digital system using similar function to IP datapackets. Yes pin 2 is +ve voltage, pin 3 is –ve voltage but both pins areused for TX/RX.
