CC640 Digital Camera 2. Introduction The CC640 digital camera was designed to meet the stringent operational requirements necessary for remote battery powered installations. The CC640 has a very low quiescent power draw and can operate over a wide temperature range. The camera contains a compact flash memory card interface that turns the camera into a powerful image logger. The combination of JPEG compression and memory card storage enables the CC640 to store over 10,000 images.
Operating Manual Table 1.
CC640 Digital Camera 2.3 Operating The CC640 is capable of acquiring images in a self-timed mode, an external trigger mode, and by manually taking a picture using the Snap button (Section 3.3, page 6). Self-timed mode is set using the Device Configuration Utility, while a short pulse applied to the Ext. Input Signal on the camera will initiate image acquisition in the External Trigger Mode. When taking a picture manually using the Snap button, the power switch needs to be in the ON position. 2.

Operating Manual 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. This is done to conserve power in its low power state.
CC640 Digital Camera Figure 4 Using C2006 adapter board to carry RS-232 TX and RX on multi-conductor cable The necessary RS-232 TX (transmit) and RX (receive) signals can also be carried by the recommended 6 conductor cable. Figure 4 demonstrates using a DB-9 to terminal breakout board (part C2006) and the standard cable to transmit the RS232 signals. This provides a practical means of carrying the RS-232 signals when the camera is installed remotely from the datalogger.
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).
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.
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).
CC640 Digital Camera 4.4 RS-485 Port The RS-485 terminals can be used in conjunction with the MD485 to interface a datalogger to the camera over distances of up to 4000 feet. The +12V GND and EXT control lines cannot be practically run these long distances. Normally the RS-485A and RS-485B lines, and an additional ground connection, are run these distances. Refer to the MD485 manual for additional information. 5.

The size of the images varies with the image content.
Operating Manual 8. Lens The standard Lenses for the CC640 camera contain the following features: • • • • CS Mount Varifocal (manual zoom) Manual Focus DC Iris The camera controls the iris of the lens using the cable with a 4-pin connector. This connector must always be plugged into the receptacle (on the front lens plate of the camera) for proper operation. 8.1 Lenses and Field of View • Currently there are 2 optional lenses for the CC640 camera. A 3.5-8mm and a 6-12mm.
CC640 Digital Camera 8.2 Focus and Zoom Adjustment The lens is equipped with manual zoom and focus adjustment rings. The most practical way to adjust the lens is by utilizing a normal Television monitor or a portable Television. • Connect an appropriate video cable from the video output connector (RCA Jack) of the camera to the video input on the video monitor of the television. • Turn the power switches of both the camera and the television to the ON position and then press the Set-up Button.
Operating Manual 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. Figure 10 Lens and Filter 9. Maintenance The CC640 requires little maintenance and no calibrations. Keeping the camera clean and in a dry environment is important for the longevity of the camera.
CC640 Digital Camera 9.2 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. 10. Set-up and Interface Guide 10.1 Trigger mode Determine how the camera will be triggered to initiate an image acquisition. There are 2 different trigger sources.
Operating Manual 10.2 Communications Communications can enable remote retrieval and/or storage of images to external devices such as compatible Campbell Scientific dataloggers. The PakBus protocol is used to facilitate the transfer of images. 10.2.1 Communications Disabled When a camera is not connected to other devices for communications then it is important to: • Set the parameter PakBus Port to None 10.2.
CC640 Digital Camera Refer to Section 4.2 for additional information and connections diagrams using the RS-232 port. 10.2.4 RS-485 Communications The camera can download images via its RS-485 port using the PakBus protocol. An MD485 can be used to transmit images via PakBus from a camera to other devices: • Set the parameter PakBus Port to RS-485 • Set the parameter PakBus Address to a unique value in the PakBus network.
Operating Manual The quiescent power consumption in Amp-Hours is calculated as follows: Pquiescent = 250x10-6 Amps * 24 Hours = 0.006 Amp-Hrs / Day The operating power usage per picture in Amp-Hours is calculated as follows: Poperating = 0.250 Amps * (30Sec. / 3600 Sec./Hr) = 0.00208 Amp-Hrs / Picture The daily power usage will depend on the number of pictures taken per day. The power usage can be calculated using the following formula: Pusage / Day = 0.006 Amp-Hrs + (0.

Operating Manual The following methods can be used to set the drive size of the USR: • The Device Configuration Utility program • PakBus Graph • Editing the parameter from the Status Table • The CR1000’s optional keypad and display. 13.2 CR1000 Files Manager The Files Manager setting on the CR1000 facilitates the management of JPEG files that are received from the camera. The Files Manager allows the user to specify a name for the files and the number of files kept in a ring memory type fashion.
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. The Null modem cable is required because both the camera and the CR1000 are DCE type devices.
Operating Manual • Send_File Sends a particular file to a station. • Delete_File Deletes a file stored in the datalogger. This is currently not supported on the CR10X datalogger. • Retrieve_File < Station > < Filename >
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). In this example the station CR10XPB is a station that is set-up in Loggernet. The Add Scheduled button can be used to create a task with a programmable schedule.
Operating Manual Figure 11 Task Set-up 35
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. To set-up a task that executes after data is collected the desired station would be selected and the Add After option would be selected in the Task Master set-up screen.
Operating Manual 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. 15.1 Enclosures Refer to Appendix A for recommended enclosures. 15.
Appendix A. Camera Enclosures 1. ENC 16/18-CC The ENC16/18-CC enclosure provides a means of housing the camera along with other equipment such as a datalogger and modem. The ENC 16/18-CC enclosure uses the same fibreglass enclosure and mounts as the standard ENC 16/18 enclosure.
