[. . . ] Consult the Matrox Intellicam User Guide for more information the virtual frame rate for the current settings of the DCF is 1. 7 Hz. In each virtual frame there are 525 lines, 480 of which are active. 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 number of blanking lines can be reduced to no less than 1. 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 once it has received the external signal to trigger, the Pulsar sends the TTL exposure signal to the camera. The camera awaits the falling edge of the signal, at which point it initiates exposure. The exposure time is set by the Pulsar; the camera will expose for as long as the exposure signal is low. The exposure time is currently set to 12 288 pixels (the clock rate is 14. 318 Mhz). The camera initiates line readout upon arrival of the rising edge of the exposure signal total line time is exposure time plus 2122 pixels; thus it is currently 14 410 pixels trigger rate can vary between 0Hz and 1Khz virtual frame size is 2048 x 480, with 1 line of vertical blanking; therefore an effective 480 lines out of every 481 lines are acquired the DCF must be modified 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 continued PUL-CID-007 3 Interfacing non-standard cameras to Matrox Pulsar Loral Fairchild CAM1830 12/02/96 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 exposure 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).
