Figure3- 6: Internal equivalent circuit of camera when Line2 is configured as input
To avoid the damage of GPIO pins, please connect GND pin before supplying power to
Line2/3.
Line2/3 is configured as output:
●
Range of external voltage (EXVCC) is 5~24V.
●
Maximum output current of Line2/3 is 25mA, output impedance is 40Ω.
●
Output voltage and output current in typical application conditions (temperature is25°C) are shown
in Table3- 7.

●
Rising time delay = tr+td: <20μs (0°C~45°C) (parameter description as shown in Figure3- 4).
●
Falling time delay = ts+tf: <20μs (0°C~45°C) (parameter description as shown in Figure3- 4).
●
Delay parameters are affected greatly by external voltage and resistance, but little by temperature.
Output delays in typical application conditions (temperature is 25°C) are shown in Table3- 8.
