SM72 Block Diagram Components

Following are descriptions for the block diagram components.
  • Scan Engine - The imaging engine captures 8-bit grayscale WVGA images at up to 30 fps, which are sent uncompressed to a companion board for processing. The engine uses a red LED for intuitive aiming and features LED illumination.
  • Decoder Interface - The decoder board is a companion decoder module for the imaging engine, which controls the engine, receives images, decodes 1D and 2D symbologies, and performs various image processing tasks. The board controls red and green LEDs for visual feedback, and supports SNAPI (Symbol Native API) as well as USB HID Keyboard through a micro USB connector. The micro USB connector provides an outlet for the various interface signals used between the SM72 and the host.
