NOTE: The digital input is electrically isolated from the rest of the camera’s electrical circuitry via
general-purpose photo couplers. The input is additionally protected with a serial 250 Ohm resistor, and
a de-bouncing circuit. Duration of any input signal should be at least 5 ms to comply with the
requirements of the de-bouncing circuit.
NOTE:
Table 2
shows the cable color for digital input and output.
