Page 10: Introduction
The combination of JPEG compression and memory card storage enables the CC640 to store over 10,000 images. The CC640 can operate in a stand-alone mode with image acquisitions triggered by the cameras own precision real time clock. Image acquisitions can also be triggered by an externally applied digital signal. -

Page 14: Power Switch
CC640 Digital Camera 3.2 Power Switch The power switch can be used to power the camera continuously on or to place the camera in Auto power mode. The switch should not be left in the On position under normal operation. Leaving the switch in the On position will prevent the camera from entering its low power quiescent mode of operation. -

repeatedly update its firmware every time the camera wakes up from its quiescent mode. 4. Communications 4.1 PakBus Communications The camera uses the PakBus protocol to send image files from the camera to the datalogger or other PakBus compatible devices. Communications are not enabled while the camera is in its quiescent mode. -

Operating Manual Figure 5 RS-232 wiring using C2006 boards with multi-conductor cable Depending on the datalogger the wires can be terminated directly on the control ports or another C2006 adapter board can be used to provide a 9-pin connector at the datalogger end (see Figure 5). -
Page 20: Connections For Configuration
CC640 Digital Camera Figure 6 Connections for Configuration The RS-232 port is used in conjunction with the Device Configuration software to change settings in the camera such as the PakBus addresses. Figure 6 illustrates the connections required for interfacing to a computer. -
Page 21: Cs I/O Port
Operating Manual Figure 7 Camera connections for CS I/O port operation 4.3 CS I/O Port The CS I/O port on the camera provides a connector for CS I/O communications. The port is designed to communicate with Campbell Scientific dataloggers equipped with CS I/O communication ports. A ribbon cable assembly (C1947) is used to provide a male 9-pin connector that can plug directly to the CS I/O port or to a SC-12 cable that connects to the CS I/O port (See Figure 7). -

Page 26: Operational Description
CC640 Digital Camera 6. Operational Description 6.1 Self Timed Mode In self-timed mode the camera is capable of waking itself up and acquiring an image. In order to place the camera in self-timed mode use the Device Configuration Software to set the Self-Timed Interval parameter to non-zero. -
Page 27: Image Quality
When the CC640 is over-exposed by an overly bright object, such as the sun in a sky shot, the over-exposed object may begin to turn black. This is a result of the CMOS image sensor being over-exposed to light and becoming saturated. -
Page 28: Jpeg Compression
CC640 Digital Camera Figure 9 Illustration of Time Stamp banner 7.4 JPEG Compression There are 5 selectable levels of JPEG compression: NOTE These are typical values with the time stamp enabled on the image (640x504 pixels). The size of the images varies with the image content. -
Page 29: Lens
• Manual Focus • DC Iris • Currently there are 2 optional lenses for the CC640 camera. A 3.5-8mm and a 6-12mm. • What does this mean? These numbers have a direct correlation to the zoom or field of view. -
Page 30: Focus And Zoom Adjustment
8.2.1 Temperature Variations and Focus The CC640 can operate under extreme temperature variations. The focus of the lens can change slightly with large variations in temperature. For example, if a lens is focused at +25°C the lens may be slightly out of focus at -30°C. The change in focus will be less noticeable if the focus is adjusted closer to the cameras operating temperature. -
Page 31: Lens Filter
8.3 Lens Filter The CC640 camera is equipped with an IR cut filter on its lens. This is threaded onto the front of the lens and is required to filter out near-infrared light that can have an undesirable affect on the images. It is recommended that the filter always be left installed on the lens. -
Page 32: Lens Cleaning
If the filter or lens requires cleaning, it is very important that only a proper lens cloth (like those included with your CC640 camera) or lens tissue be used. The use of inappropriate materials to clean the lens can permanently damage or reduce the effectiveness of the filter or lens. -

11. Power Calculations and Timings The CC640 was specifically designed for operation in power-constrained systems such as solar powered sites. It is critical in such systems that the power switch on the camera always be left in the AUTO position to take advantage of the low power mode. -
Page 35: Operation With Communications
The quiescent power consumption in Amp-Hours is calculated as follows: = 250x10 quiescent The operating power usage per picture in Amp-Hours is calculated as follows: = 0.250 Amps * (30Sec. / 3600 Sec./Hr) = 0.00208 Amp-Hrs / Picture operating The daily power usage will depend on the number of pictures taken per day. The power usage can be calculated using the following formula: / Day = 0.006 Amp-Hrs + (0.00208 Amp-Hrs * Number of Pictures Per Day) usage... -

CR10X Interface Guide This section contains information for interfacing the CC640 camera to the datalogger. The CC640 camera can interface to the CR10X datalogger via I/O port directly or through an MD485 interfac 12.1 CR10X Datalogger Requirem It is highly recommended that the datalogger be a 2Meg datalogger. The datalogger must also contain the PakBus operating system to support the communications and file storage capabilities. -

13. CR1000 Interface Guide This section contains information for interfacing the CC640 camera to the CR1000 datalogger. The CR1000 and the CC640 both have several different types of communication ports. This provides many different interface options for the user. This includes using the CS I/O port, the 9 Pin RS-232 Serial Port, the control COM ports (1-4), and RS-485 if using an MD485 interface. -

CC640 Digital Camera Refer to Figure 7 Camera connections for CS I/O port (page 13) for an illustration of the connections between the camera and the CR1000 datalogger. 13.4 CR1000 RS-232 Port Communications The camera can be connected to the 9 pin RS-232 port of the CR1000. A Null modem cable or adapter must be used between the camera and the CR1000. -
Page 41: Using Loggernet File Control
• Send_File <Station> <Filename> Sends a particular file to a station. • Delete_File <Station> <Filename> Deletes a file stored in the datalogger. This is currently not supported on the CR10X datalogger. • Retrieve_File < Station > < Filename > <Output Filename > This should be the only command required to collect images with the CR10X. -
Page 42: Task Set-Up / Lncmd.exe
CC640 Digital Camera 14.3 Task Set-up / LNCMD.EXE Automated image collection can be achieved by setting up a Task in Loggernet that executes the LNCMD.EXE executable. A sample screen of a Task set-up that executes LNCMD.EXE is shown in Figure 11 Task Set-up (below). -

Page 44: Task Using Add After To Collect Images After Scheduled Call
CC640 Digital Camera In the above example the task will execute on its own schedule separate from data collection. A task can also be created that calls the LNCMD.EXE after scheduled data is collected. This may be more desirable for stations that are called using a dial up connection to eliminate separate dialling for data and images. -
Page 45: Installation
15. Installation The camera must be installed in an environmentally sealed enclosure that offers protection from moisture or high humidity. It is also recommended that desiccant be installed in the camera enclosure to absorb excess humidity. Failure to install or replace the desiccant as required may cause malfunctions or damage the camera. -

CC640 camera. The procedures are useful to do a quick check on the camera’s operation and familiarize the user with focusing. These procedures are intended for use only as an initial check of the CC640’s operation. It is recommended to read the CC640 manual prior to deployment in the field. - Page 54 STEP 4: Connect your TV or video monitor to the video-out port on the back of the CC640 and turn it on. STEP 5: Move the toggle switch on the back of the CC640 to the ‘On’ position. Observe that the LED flashes 4 times. This is a normal power on sequence.
- Page 55 Snap button. NOTE Refer to the CC640 manual for operation with a compact flash memory card. If a properly formatted memory card is inserted in your camera, pressing the Snap button will store the images to the memory card.
