Continuous line scan (analog or digital video outputs) · The line scan rate and the exposure time are determined by the frequency of the hsync (CLTout) signal; the exposure time is the period of the CLTout signal, which is set using the thumb wheel on the rear of the camera. PUL-CID-019 5 Interfacing non-standard cameras to Matrox Pulsar i2S iVC185BC Special Considerations Application Note: May 27, 1996 · The thumb wheel settings correspond to the following exposure times: Position 0 1 2 3 4 5 6 7 8 9 Exposure time 250µs 500µs 1ms 2ms 4ms 8ms 16ms 20ms external mode 2. Asynchronous line scan (analog or digital video outputs) · · · · · The thumb wheel on the rear of the camera must be set to position 9: external mode The line scan rate and the exposure time are determined by the frequency of the external trigger signal; the exposure time is the time between external trigger signals Once it has received the external signal to trigger, the Pulsar sends the asynchronous RS422 EXPOSURE1 (LTin) signal to the camera to initiate line readout. The camera returns the RS-422 hsync (CLTout) and pixel clock (RCLK) signals to the Pulsar The first frame to be read out will be inaccurate; the exposure time is the time between trigger signals, therefore the first frame will correspond to the first trigger signal and the one previous to it. The correct frame will be read out on the second trigger signal Trigger rate can vary between 50Hz and 3. 9kHz 3. Exposure control line scan (analog or digital video outputs) · · · The thumb wheel on the rear of the camera must be set to position 9: external mode The line scan rate and the exposure time are determined by the frequency of the periodic trigger signal supplied by the Pulsar; the exposure time is the reciprocal of the frequency of this signal Once it has received the external signal to trigger, the Pulsar sends the periodic RS-422 EXPOSURE1 (LTin) signal to the camera. The camera returns the RS-422 hsync (CLTout) and pixel clock (RCLK) signals to the Pulsar PUL-CID-019 6 Interfacing non-standard cameras to Matrox Pulsar i2S iVC185BC Special Considerations · Application Note: May 27, 1996 The frequency of the periodic EXPOSURE1 signal can vary between 50Hz and 3. 9kHz. The frequency of this signal can be adjusted though the use of Intellicam: load the proper DCF and go into Camera Spec. Move the cursor down to EXPOSURE such that the words "periodic generated" are selected and press enter; an interface entitled "Exposure signal information" will open. The frequency of the periodic EXPOSURE1 signal, and thus the exposure time itself, can be modified by changing the time specified for Tlow.
