Page 5: Introduction To The Ca-D6
The CA-D6-xxxxW cameras use DALSA’s patented modular architecture. This system of connecting circuit modules through standardized busses allows DALSA to build a high performance modular camera using the reliability, flexibility, and cost-effectiveness of high-volume interchangeable parts. Within the camera, a timing board (PB-D6-X205) generates all internal timing and a driver board (PB-D6-A198) provides bias voltages and clocks to the CCD image sensor. - Page 6 0 .8 0 .6 0 .4 0 .2 4 00 5 00 6 00 7 00 8 00 9 00 1 00 0 W ave le n gth (n m ) R e sp o n sivit y 03-32-00225-06 DALSA INC.

EXSYNC and optional signal PRIN. These signals must be supplied from your framegrabber to the camera using EIA-644 (differential) format, which requires the use of twisted pair cable. DALSA recommends shielded cables. Maximum cable lengths depends on environmental factors and EIA-644 limitations. See Appendix A. - Page 13 Keeping PRIN high maximizes the time the sensor is exposed to light.

The camera’s electronics are housed in a rugged anodized aluminum case. Mounting For maximum stability and best heat sinking, DALSA recommends mounting the camera by its front plate. There are four M4 holes and seven 4-40 UNC holes tapped into the front plate for mounting the camera or attaching heat sinking. -
