8.4.3.5.1 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.
8.4.3.5.2 Light Power Control Settings
The camera can be configured to switch the ex12 V on, based on the
available light in the scene (yellow wire). There are three settings: Not Used ,
Active , and Flash Type . Not Used disables the output, while the other two
enable it.
There are future plans to add two 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.
8.4.3.5.3 Communication Power Control
The Communication Power Control setting controls the communication
switched power output line on the Power and 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.
8.4.3.5.4 Heater Power Control
The Heater Power Control setting controls the operation of the optional
window defroster. If enabled, the camera will only turn on the heater if the
current internal temperature is below the threshold setting. The temperature
threshold values are limited to –40 to 25 °C.
If the Always On option is selected, the heater will be on whenever the
temperature is below the threshold and the camera is not in a low powered
state.
If Minutes prior to schedule is selected, the camera will wake up prior to any
of the Self Times schedules and turn on the heater if the temperature is below
