The on-board amplifier processes the video signal to produce a sequential stream of video

at the video output pin of the PI404MC-A8 module.

Illumination is by means of an integrated LED light source. All components are housed in

a small plastic housing which has a cover glass which acts as the focal point for the object

being scanned and protects the imaging array, micro lens assembly, and LED light source

from dust. I/O to the module is the 10-pin connector located on one end of the module.

See Figure 4, Mechanical Structure on the last page. The cross section of the PI404MC-

A8 is shown in Figure 1 and the block diagram in Figure 2.
