optical Signal, emitted of Transceiver
optical Signal, received of Transceiver
Note:
Transmitter and Receiver invert the signals, which means that
-
in standard transmitting mode: low level (0V) at DI causes the illumination of the LED (LEDO
1
=
light on) and vice versa,
-
in standard receiving mode: no light onto the Photodiode (PDI
0
= light off) causes output of 5V at
DO and vice versa.
