Model 512 is a legacy product and is not recommended for new designs. Legacy products are available but may have lead times up to 12 weeks and minimum order requirements. We recommend model 953 as a substitute for this product.
Model 512 is a PC/104 frame grabber that captures and transfers full-frame (640x480) video at 30 frames per second. It overcomes the low bandwidth of the PC/104 bus by using hardware compression to produce encoded MPEG2 data streams of 100 kbits to 10 Mbits per second.
MPEG-2 data reduces the amount of memory required to store full motion video. The compressed data requires a smaller transmission bandwidth. This makes it possible to transmit 30 frames/second video over the PC/104 bus or over a 10/100 Base-T Ethernet. The hardware compression circuit uses a motion estimation algorithm to produce smooth images from interlaced cameras. The length of MPEG-2 video streams is not limited by the viewing software.
Encoded MPEG-2 data can also be decompressed by the 512's hardware to produce composite video. The video output is available at a flat cable header.
The 512 has four multiplexed video channels that function as four separate composite channels or as two S-video inputs. This model does not support audio. For an MPEG-2 frame grabber with audio, see our model 516.
Three bi-directional logic lines are under software control.
Digitized video inputs can be looped back to the output circuits to allow camera adjustments. The 512's D/A can be programmed to generate color test bars. This is useful for testing the video output channel.
