Introduction
The Symbol PL4507 is a companion decoder module for the Symbol SE4500 imager engine, and controls the
imager, acquires images, and decodes 1D and 2D symbologies. For information on the SE4500 imager engine,
refer to the Symbol SE4500 Integration Guide, p/n 72-112996-xx.
The Symbol PL4507 is a hybrid, multi-chip processing system, composed of an XScale core and related
subsystems. The PL4507 includes asynchronous serial (the standard Symbol Simple Serial Interface/SSI
command set) and SNAPI (Symbol Native API) interfaces, as well as USB keyboard emulation, and a variety of
RS-232 host interfaces.
Symbol PL4507 architecture includes:
•
Marvell PXA320 microprocessor core, 624 MHz
•
64 MB Double Data Rate (DDR) Synchronous DRAM
•
128 MB asynchronous flash
•
Camera Sensor Interface (CSI) port
•
Host communication port.
System peripherals include:
•
One UART (RS-232) channel: SSI support for compatibility with existing devices and applications
2
•
I
C bus used for camera control
•
USB 2.0 Full Speed port for image and bar code data transfers.
This integration guide describes the decoder theory of operation, installation, specifications, and configuration.
