Figure 7-16 Digital I/O Settings
7.4.5.1 External Trigger Input Settings
The External Trigger Input can be configured to Active High or Active Low. When
set to Active High 0 volts will be the Inactive state and a positive voltage will be
the Active state.
The CC5MPX is shipped from the factory by default with a pull down resistor
connected to the External Trigger Input and the External Trigger is set to Active
High. With this default setting, when no signal is applied to the input the External
Trigger is inactive. A positive voltage is required to change to the active state.
7.4.5.2 Light Power Control Settings
The camera can be configured to switch the external +12 V on, based on the
available light in the scene (Yellow wire). There are 3 settings: Not Used, Active,
and Flash Type. ‘Not Used’ disables the output, while the other 2 enable it.
There are future plans to add 2 different modes of operation, but currently they
operate in the same manner. The light will only come on when capturing from a
self-timed capture or when an external trigger occurs while the camera is in sleep
mode. The light does not turn on for motion detection capture. The light turns off
after the capture is complete.
7.4.5.3 Communication Power Control
The Communication Power Control setting controls the Communication Switched
Power Output line on the Power I/O cable of the CC5MPX camera.
The switch output is intended to manage the power to a communication device,
such as a cell modem. This is useful in a solar powered site when there is a need to
limit power consumption of communication devices.
This option enables the CC5MPX to supply up to a maximum of 750 mA of
current. The voltage level will be the same as the camera’s input power (i.e. 12
VDC).
Some modems will require a warm up time or a period of time to register on a
network. The Communication warm up time parameter allows an appropriate time
to be entered for this purpose.
