Details

• 1024 x 1021 x 12-bit @ 8fps (max)

• digital video output (RS-422)

• non-interlaced

• internal hsync, vsync and pixel clock signals (all RS-422) supplied externally

• 10MHz pixel clock rate

Continuous mode

• 1024 x 1021 x 12-bit @ 8fps (10-bit acquisition also available)

• Digital video output (RS-422)

• Non-interlaced

• Continuous video

• Matrox Pulsar receiving RS-422 hsync (Line Valid or LVAL), vsync (Frame Valid or

FVAL) and pixel clock (STROBE @ 10MHz) signals from camera

• DCF used: CAD7T12.DCF (12-bit acquisition); CAD7T10.DCF (10-bit acquisition)
