I need to create an ICD file for RS-343 (875 line) standard analog video. I am using a PCI-1409 and will soon be using a PCI-1410. I tried speaking with NI tech support and they encouraged me to try and modify the RS-170 ICD file but could not give me any specifics on paramters or syntax. After searching these forums it appears that this question has been asked before but at a higher resolution and was subsequently dimissed because the presumed pixel clock of the RS-343 was above the supported 40MHz of the PCI-1409/1410. The RS-343 I am trying to interface is the standard military monochrome 875-line and has the following general specifications...
Active Line Length: 960 pixels, 30.99 usec.
Vertical Active Height: 802 lines
Nominal Line Period (total width): 1180 pixels, 38.10 usec.
Lines Per Frame: 875 lines
Pixel Clock: 30.975000 MHz, period = 32.284100
nsec. Horizontal Line Frequency: 26.250 KHz
Horizontal Sync Duration: 85 pixels, 2.74 usec.
Horizontal Back Porch Duration: 105 pixels, 3.39 usec.
Horizontal Front Porch Duration: 30 pixels, 0.97 usec.
Vertical Front Porch Duration: 3540 pixels, 3.0 lines, 0.11 msec
Vertical Sync Duration: 3540 pixels, 3.0 lines, 0.11 msec
Sync Pulse Duration: 530 pixels, 17.11 usec
Sync Pulse Count: 6
Vertical Back Porch Duration: 36580 pixels, 31.0 lines, 1.18 msec
VWALK to ACTIVID duration: 10640 pixels, 9.016949 lines
Frame Frequency: 30 Hz Interlaced, 2 Fields
If anyone out there can lend a hand on this I would be much appreciated.
Thanks.
