[. . . ] The line rate is fixed and is determined by the frequency of the EXSYNC signal. The HSYNC parameter in the DCF specifies the line rate of the camera and therefore the exposure time. The line rate of the camera, and therefore the exposure time, can be modified in the DCF using Matrox Intellicam. The virtual frame rate for the current settings of the DCF is 287µs x 512 = 146. 9µs = 6. 8Hz. 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).
