??
The interval is programmable from 0 seconds (takes pictures as fast as the camera can cycle), to
255 Hrs, 59 Mins, 59 Seconds (over 10 days).
??
The number of images can be set from 0 to 65535, where 0 indicates Infinity (takes pictures
forever).
??
The initial delay can be set from 0 to 65535 minutes, allowing a delay between power-up and the
beginning of the time-lapse sequence.
3) Advanced Time-Lapse (ATL)
ATL allows for time-of-day triggering of time-lapse sequences, unrelated to when the system is
powered on. Up to eight sequences may be enabled, with start time (per 24 hr clock), interval, and
number of pictures all configurable.
Power Management
The DigiSnap 3000 is designed for minimum power drain, and can control the timing of external lighting
and camera power maximum battery life. The DigiSnap 3000 controls the power to the camera, external
lighting, and auxiliary internal power, timing each to come on as required to support image acquisition.
As an example, consider a battery powered, un-attended ATL application, where 10 images are to be
acquired at each of four times per day, with an interval of 5 minutes. The camera, and external lighting
would be configured to power on just before each image is acquired, and turned off after it is stored on the
camera’s internal memory card. The DigiSnap 3000 would operate full-time, but is itself designed for low
power.
Other Features
The DigiSnap 3000 manages the electrical signal flow for all of the equipment associated with the camera
assembly and housing. Many of these signals are controllable via the terminal interface. All electrical
connections are made to this circuit board through connectors designed to be polarized and unique to each
function. Replacement of a camera assembly, housing swaps, etc. may be readily accomplished with
minimum potential for miss-connection.
DC Power
The DigiSnap 3000 incorporates an isolated switching power supply to convert the applied DC power to
the bias levels required for all internal functions, including the camera. The acceptable DC power input
range is 9-36 VDC.
Video Output
The video output of the camera is buffered by the DigiSnap 3000 for driving long cables.
High Speed Image Download
The USB port of the camera is routed through the DigiSnap 3000 as well, however USB is not suited for
long distance operation.
High Capacity Lighting
The DigiSnap 3000 has an on-board isolated switch for controlling local lighting for the camera, having a
switching capacity of 10 amps for short periods (i.e. 30 seconds, 10% duty cycle). The long term current
capacity is 5 amps, due to thermal dissipation on the circuit board. The voltage is the same as that supplied
to the housing, so at 36 volts, the total external switched power can be as high as 360 watts.
