Pin Description
1
DO_COM
DO: Digital Output;
each digital output pin to
COM (Pin1) is a photo-coupled relay on Normal
Open status. External device can directly connect to
the terminals. However the current that will go
through the 2 nodes must not exceed 130mA. An
external “Relay” can also be connected to the
terminals as an implementation. In this case, current
(or/and voltage) limitation is specified by the
external Relay.
DI: Digital Input;
Only one set is designed in this
Camera Model. The internal device is also
photo-coupled electrical relay; and the external
device can be simply an On/Off switch. Each set of
On/Off switch can be connected as one trigger
source.
Default Setting:
Short Pin4 and Pin5 with a wire
PIN with a short wire to revert to factory default
settings. Break the short when the LED starts quick
flashing, and then camera will reboot automatically
a few minutes later.
