MiniScan MS-320X Integration Guide

Miniscan Block Diagram Descriptions

Decoded Scan Engine - The scan engine emits a beam of laser light that reflects off the

bar code to be decoded. Black bars absorb light, white spaces reflect light. The scan engine

collects the reflected light and processes the signal through several analog filters. The

filtered signal is digitized into a Digitized Barcode Pattern (DBP). Timing information is

analyzed by the decoder micro-controller to decode and transmit the data contained in the

bar code. Data transmission is carried out using Symbol's proprietary SSI Interface.

Interface Board - The interface board adapts the scan engine's SSI interface into usable

signals and data for the intended host. It also contains a beeper and red/green LED for

audio/visual feedback, as well as provisions for an external trigger and external beeper.

• The MS-3204 interface board converts TTL level SSI signals to proper RS-232

levels for connection to any RS-232 compliant host.

• The MS-3207 interface board converts the scan engine's data to Synapse, USB,

or TTL level RS-232. A separate host adapter cable (p/n 25-62186-XX) is available

to convert the TTL level RS-232 output to standard RS-232 levels. All interface

types are auto-detected based on the host cable attached.

DB9 - The DB9 connector provides a sealed outlet for the various interface signals used

between a MiniScan scanner and it's host. It also maintains pin compatibility with the

previous generation LS 1220 MiniScan host cables.
