The light and communication power control output are in parallel
on the same wire on the connector. If both powers are enabled, the
output remains on from the start of capture to when the file transfer
is complete.

The
Modem
Power
Control
setting controls the yellow Power I/O signal line of
the CCFC 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 CCFC 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 require a warm up time or a period of time to register on a
network. The
Early Power On
option is there for this purpose. Enter a value in
seconds; the maximum value that can be entered is 300.
