Symbol MS4404/MS4407 Integration Guide

.

Imager Engine - The SE4400 engine provides digital images which can be transmitted to a decoder to decode a 
bar code of any format supported by the decoding software. The engine utilizes laser aiming and an LED illumination 
system, and can switch between two focus positions for extended working range or for more precise focusing in 
high-density bar code decoding or digital picture taking.

Interface Board - The interface board adapts the imager engine's interface into usable signals and data for the host. 
It also contains a beeper. LED illumination and red/green LED for audio/visual feedback, and provides for an 
external trigger and external beeper.

The Symbol MS4404 interface board converts TTL level SSI signals to proper RS-232 levels for connection to any 
RS-232 compliant host, and the Symbol MS4407 interface board allows connection to logic level serial and USB 
hosts.

Voltage Regulator (Symbol MS4404 only) - The power supply allows the Symbol MS4404 to operate of the 
extended input voltages of 5 - 12 Vdc.

DB9 - The DB9 connector provides an outlet for the various interface signals used between a MiniScan and the host. 
It also maintains pin compatibility with MiniScan (MSXXXX) host cables.
