DI/DO Specifications

Pin 1
FUNCTION
Uses an open-drain NFET transistor with the source connected to GND in camera. If used
with an external relay, a diode must be connected in parallel with the load for protec-
tion against voltage transients. Max loading is 100 mA.
DC 5 V Output / Max. 100 mA
A switch from DI to GND, activated by setting NO. or NC.
