User manual MAXTOR CLC31024N

[. . . ] Line scan rate is fixed and is determined by frequency of EXSYNC signal. Matrox Pulsar sending RS-422 EXPOSURE1 (PRIN), RS-422 EXPOSURE2 (EXSYNC) and RS-422 Reference clock (MCLK) signals to camera; the EXPOSURE1 and EXPOSURE2 signals control the exposure time and initiates line readout. Matrox Pulsar receiving RS-422 pixel clock (STROBE @ 15 MHz) and RS-422 VSYNC (LVAL) signals from camera; the LVAL signal indicates valid lines (pixels). [. . . ] The clock rate is 15 Mhz; the line rate is therefore 3. 5KHz. The line rate of the camera, and therefore the exposure time, can be modified in the DCF using Matrox Intellicam. Consult the Matrox Intellicam User Guide for more information. The virtual frame rate for the current settings of the DCF is 287µs x 512 = 146. 9µs = 6. 8Hz. In each virtual frame there are 512 active lines. The host buffer of the Matrox Pulsar can grab images of up to 2048 x 2048 (4MB) and the display buffer can grab images of up to 2048 x 1024 (2MB) The time between the rising edge of the EXPOSURE1 and EXPOSURE2 signals is the exposure time. In order to select the exposure time, the width and deployment time of each EXPOSURE 1 and EXPOSURE 2 must be set in Matrox Intellicam.

Line rate is variable and is controlled by the external trigger signal. Virtual frame size for this DCF is 1024 x 1 x 512 Once it has received the external signal to trigger, the Matrox Pulsar sends the RS-422 EXPOSURE1 (PRIN) signal to the camera to initiate exposure. The Matrox Pulsar will send the RS-422 EXPOSURE2 (EXSYNC) signal to the camera following a delay that is equal to the desired exposure time. A short (variable) delay after receiving the EXPOSURE2 pulse, the camera sends the RS-422 LVAL signal to the Matrox Pulsar to indicate line readout (line valid).
