Page 4: Introduction
We thank you for purchasing from the DVC-340 product line. The DVC-340 cameras are based on the Kodak KAI-0340 interline CCD, which provides 640(H) x 480 (V) pixel resolution and 7.4 µm square pixels with high quantum efficiency and low noise. The DVC- 340 is available with either Gigabit Ethernet or CameraLink digital video and control interface. -
Page 5: Receiving And Unpacking
Receiving and Unpacking Your DVC-340 camera was thoroughly tested and carefully packed at the factory. Once the camera shipment is accepted for delivery, the carrier assumes full responsibility for its safe arrival. Should you receive your shipment with any damage—concealed or apparent—please contact the carrier at once. The carrier will instruct you on how to initiate a damage claim. -

Page 7: Operating Speed
The DVC-340 has five basic operating modes described in detail below. Each mode can be operated at either 20 or 40 MHz and can support binning and region of interest. All operational modes are initiated by a trigger signal. In the continuous modes, the trigger initiates the stream and the camera continues to run in streaming mode until disabled by the host computer. -

(falling) edge of the external or CameraLink control lines, with an exposure time set by software. Alternatively, the exposure can be initiated by the host via the DVC API. The exposure and readout sequence is the same as the non-... -
Page 9: Bulb (Pulse-Width Exposure) Mode
Bulb mode in the DVC-340 is analogous in that the CCD exposes as long as the trigger signal is asserted (a low logic level on the external trigger or a low command on the CameraLink CC1 control line). -
Page 10: Region Of Interest
The KAI-0340 CCD is a high-performance image sensor with remarkably ideal behavior over a wide operating range. To be as versatile as possible, the DVC-340 camera exploits as much of the CCD capability as possible and provides the user a great degree of control over the CCD functions. As a result, it is possible to observe some interesting, low-level CCD phenomena under certain extreme conditions. -
Page 11: Maintenance
To minimize the need to clean the optical surfaces, do not remove the protective lens mount cap shipped with the DVC-340 camera until you are ready to mount the camera to the optical system. - Page 12 • dry location where it is safe to use flammable solvents (please see caution below) Carefully loosen the lens mount lock ring using the supplied DVC lock ring • wrench. Orient the camera so that the lens mount is pointing downward and carefully •...

Caution: This procedure will cause the focus calibration to be lost. Readjustment of the lens back-focus will be required after reassembly Loosen the lens mount lock ring with the wrench supplied by DVC Unscrew the lens mount/filter assembly ring from the camera body and remove the lock... - Page 14 Remove the filter from the filter ring with lens tissue and store in a protective container Replace the lens ring on to the filter ring and screw on clockwise Remove the lens ring from the lens cap Screw the lock ring back onto the lens mount ring and screw both back onto the camera. Adjust focus by loosening the lock ring and rotating the lens mount ring to adjust the lens-to-CCD distance.

Use a CLEAN, DRY (preferably brand-new), camel-hair lens cleaning brush • (such as those used by photographers) to gently wipe the contaminants off of the CCD Faceplate. If in doubt, or if the CCD faceplate surface is very dusty, please call DVC • customer service before proceeding. •... -
Page 16: Warranty And After-Sale Service
DVC such as lenses, optical and electro-optical assemblies, power supplies, cables, image processor boards and software are warranted by the original manufacturer. This warranty is in lieu of all other warranties expressed or implied. DVC shall not be liable for any collateral or consequential damages. - Page 17 In no event will DVC be liable for any direct, indirect, special, incidental or consequential damages, including lost profits, lost business, or lost data, resulting from the use or reliance upon the information, whether or not DVC has been advised of the possibility of such damages.

Page 18: Appendix A: Exposure Timing Diagrams
Appendix A: Exposure Timing Diagrams Continuous, overlapped, electronic-shuttered exposure mode In the continuous, overlapped exposure mode, the camera remains in an idle state until the falling edge of the trigger. A first exposure is made, followed by the typical, interline CCD overlapped exposure/readout cycle. - Page 19 Continuous, overlapped, extended-exposure mode This mode is similar to the overlapped, electronic-shuttered exposure mode except that the electronic shutter is not enabled and the exposure times are greater than one readout cycle (frame time). As a result, readout frame rate will decrease as exposure time is increased, but the overlapping exposure and readout provide the maximum frame rate for a given exposure time.
- Page 20 Continuous, non-overlapped exposure mode This mode is similar to the overlapped exposure mode except that the exposure and readout periods are separate and do not overlap. As a result, readout frame rate will decrease as exposure time is increased. This mode also offers much longer integration times than overlapped exposure mode, and exposures are controlled via software.
- Page 21 Edge-triggered exposure (single frame capture) mode Edge-triggered exposure mode operates almost identically to the first frame of the non-overlapped continuous mode except that instead of continuing to run, the camera returns to the armed state, waiting for another trigger. Exposure is controlled by software. trigger ignored during exposure and readout trigger ignored during exposure and readout software...
- Page 22 Bulb (pulse-width exposure) mode Bulb mode allows the camera exposure to be controlled by the external trigger signal. The leading edge of the trigger signal initiates the exposure, and the camera will continue to expose until the trailing edge of the trigger, as shown. The readout sequence begins immediately after the trigger signal trailing edge, and at the end of readout, the camera returns to the armed state, awaiting the next trigger.

Page 24: Pin 3, Ttl_Reset
DIFF_RESET_OUT is labeled INPUT_1 on older DVC cameras and on the Mini-DIN- to-BNC cable accessory sold by DVC. Pin 3, TTL_RESET TTL_RESET is a TTL input used to trigger exposures. It functions identically to the CameraLink CC1 signal. TTL_RESET is also labeled VRST_INT on older DVC cameras and on the Mini-DIN-to-BNC cable accessory sold by DVC. -
