[. . . ] Interfacing non-standard cameras to Matrox Pulsar Loral Fairchild CAM1351 Camera Interface Overview · · · · Application Note: 03/06/96 1024 x 1 x 8-bit analog video output 20MHz pixel clock rate mode of operation: variable line scan rate with external exposure control Camera Interface Details Variable line scan rate with external exposure control Video Data rate in Data rate out Line/Integrate e Line sync out LORAL C. 1351 Matrox Pulsar (with PLS-TTL-CABLE) · · · · · · · · 1024 x 1 x 8-bit TTL external trigger analog video output DCF configured for 800 lines per virtual frame the line scan rate is determined by the frequency of the EXPOSURE1 (Line/Integrate) signal, which is the frequency of the external trigger signal. [. . . ] The rising edge of the signal initiates line readout; the readout of a line of data is delayed by 1 or 2 clock cycles from the arrival of the rising edge of the EXPOSURE1 signal the line scan rate is determined by the frequency of the Line/Integrate (EXPOSURE1) signal, which is the frequency of the external trigger signal. The time between external trigger signals must be greater than the sum of the exposure time and the line transfer time (51. 2µs) The exposure time is the duration of the low cycle of the Line/Integrate signal; the exposure time can be altered by modifying the low period of the EXPOSURE1 signal provided by the Pulsar. The width of the low portion of this signal can be adjusted though the use of Intellicam: load CA1351AL. DCF and go into Camera Spec. Move the cursor down to EXPOSURE such that the words generated on trigger"are " selected and press enter; an interface entitled Exposure signal information"will open. " The exposure time can be modified by changing the time specified for T pulse width. Under the heading of sec. , select the exposure time in seconds; the value of T pulse width must be greater than 2 clock cycles, which corresponds to 0. 1µs for a pixel clock of 20MHz. To complete this operation by accepting and computing the registers etc. , follow the instructions in the Intellicam User Guide. The default setting of the exposure time is 1. 5ms, thus the external trigger rate for the current settings of the DCF must not exceed 645Hz continued · · · PUL-CID-021 2 Interfacing non-standard cameras to Matrox Pulsar LORAL CAM1351 · Application Note: 03/06/96 the DCF is configured for 800 active lines per virtual frame. The number of active video lines can be altered by using Matrox Intellicam to modify the DCF. 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 DCF(s) mentioned in this application note can be found on the MIL and MIL-Lite CD, or our FTP site (ftp. matrox. com). The information furnished by Matrox Electronics System, Ltd. is believed to be accurate and reliable. [. . . ] 1901, 19/F, Workington Tower, 78 Bonham Strand E. , Sheung Wan, Hong Kong.
