Design The Piranha camera uses 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 Piranha camera, a timing board (PB-P1- X206) generates all internal timing and a driver board (PB-P1-X138 for resolutions up to 2048;...

(0-255 for 8-bit cameras, 0-4095 for 12-bit cameras). These digital numbers are what the camera outputs as data to a framegrabber. For more information on terms and concepts from the digital imaging industry, see DALSA’s current Databook Glossary, CCD Technology Primer, and Application Notes.

Frequency = 40kHz µ desired resolution You require 1 pulse for every 100µm of Shaft Encoder object travel. Assuming a shaft/web Circumference encoder producing 1000 pulses/rev., shaft = 0.10m circumference must be 1000 x 100µm 2.3 Input/Output DALSA Corp. 03-32-00253-13...
The companies listed below make power supplies that meet the camera’s requirements, but they should not be considered the only choices. Many high quality supplies are available from other vendors. DALSA assumes no responsibility for the use of these supplies.

Figure 4. 3.2 Mounting For maximum stability and best heat sinking, DALSA recommends mounting the camera by its front plate. There are four M4 threaded holes and seven 4-40 UNC holes tapped into the front plate for mounting or attaching heat sinking. Other mounting options include M4 holes on the sides of the camera (stability increases with number of sides used) and the tripod mount (least stable).

With the typical system as base, follow these specific guidelines to ensure best performance: • Keep control and data cables as short as possible. • Ensure that all cable shields have 360° electrical connection to the connector. • Fasten and secure all DB25 connectors with screws.

EXSYNC must toggle (300 Hz min.). The camera will not output lines if EXSYNC is restricted to logic HIGH or logic LOW. Using an oscilloscope, check the camera end of the control signal cable to verify that EXSYNC and EXSYNCB toggles. DALSA Corp. 03-32-00253-13...
