[. . . ] The total line time is currently set to 2149 pixels; this figure includes the total number of active (2048) and blanking (101) pixels in one line of data. 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 6. 88Hz. Both the number of active video lines and the number of blanking lines can be altered by using Matrox Intellicam to modify the DCF; the virtual frame rate will be altered accordingly. 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) Mode 2: Variable line scan rate · · · · · · PSG FPGA version 3. 01 or newer is required The line rate is variable and is controlled by the external trigger signal; the exposure time is inversely proportional to the line rate Once it has received the external signal to trigger, the Pulsar sends the RS-422 EXPOSURE2 (EXSYNC) signal to the camera. The camera awaits the rising edge of the signal; a short (variable) delay thereafter, the camera sends the RS-422 LVAL signal to the Pulsar to initiate line readout. The LVAL signal is high for the period during which a line of data is being read out Trigger rate can vary between 0Hz and 0. 68Khz Virtual frame size is 2048 x 480, with 4 lines of vertical blanking; therefore an effective 480 lines out of every 484 lines are acquired With an optional LCD electronic shutter, the exposure time can be controlled independently of the external trigger signal and is set in the DCF at the hardware register level. A hardware register editor is provided by running Intellicam with the -hwreg option (specifically by running INTELCAM -hwreg). An additional menu item, "HW REGISTER EDITOR", appears on the main menu screen. The following registers are used to define exposure timings: CTRL_SET1CNTL CTRL_SET1CNTH CTRL_T1STARTL CTRL_T1STARTH PUL-CID-012 4 Interfacing non-standard cameras to Matrox Pulsar DALSA CL-E1-2048A May 29, 1996 Application Note: These last are two 16-bit registers that have been split in two: the low byte and the high byte. To set these registers, note first that CTRL_SET1CNTL must be equal to CTRL_T1STARTL and that CTRL_SET1CNTH must be equal to CTRL_T1STARTH; this minimizes the delay between the time the Pulsar receives the external trigger signal and the time it sends the hsync or EXPOSURE1 signal to the camera. These values must be in pixels and must be set in hexadecimal; the value of each 16-bit register can vary between 0 (0000 in Hex) and 65 535 (FFFF in Hex). The default width of the EXPOSURE1 pulse for use of this camera with an optional LCD electronic shutter is 8192 pixels, which in hexadecimal is 2000; at a clock rate of 7. 159mhz, this corresponds to an exposure time of 1. 14ms. The registers are set in the following way: CTRL_SET1CNTL CTRL_SET1CNTH CTRL_T1STARTL CTRL_T1STARTH 0H 20H 0H 20H When computing the hardware registers, the following question may be asked: "Some registers have been manually edited.
