INTRODUCTION

The IS4800 microQuest®series are miniature single-line scan engines designed

for direct integration into customer decode-equipped OEM devices.

The microQuest non-decode scan engine is equipped with a multitude of

features including:

•100 Scans per Second, Typical.

•Support for 3.3VDC Input Voltage (IS4813 Model)

•Support for 5VDC Input Voltage (IS4815 Model)

•A 650 nm Bright Laser Diode

•A narrow exit angle to provide precision beam positioning.

•Automatic (Hardware) Scan Sense

•A rugged industry standard size die cast chassis with threaded mounting

holes.

•A 10-pin ZIF Connector Industry Standard Pinout for Seamless Integration

into Portable Devices

•Low Mass (11 grams) Industry Standard Size

The manufacturer of the end equipment must register with agencies such

as the Food and Drug Administration (FDA). The specifications required

for registration are not obtainable until the OEM manufacturer uses the

microQuest Engine in its final configuration. Therefore, it becomes the

responsibility of the manufacturer who incorporates the scan engine into

their product to comply with all federal laser safety regulations.

The manufacturer must submit a Laser Product Report for the FDA in the

US. Metrologic will assist its customers in complying with the necessary

procedures.

THIS DEVICE DOES NOT COMPLY WITH 21 CFR 1040.

USE ONLY AS COMPONENT.

Caution: The laser is susceptible to permanent damage if enabled less

than 50 ms after the Scan Enable has been activated. This requirement

must be strictly adhered to or the limited warranty on page 23 is void.

Refer to Scan Sense Timing on pages 16 - 17 for additional information.

MOUNTING SPECIFICATIONS

Enclosure Specifications

The IS4800 scan engine series was specifically designed for integration into

custom housings for OEM applications. The scan engine’s performance will be

adversely affected or permanently damaged when mounted in an unsuitable

enclosure.

THIS DEVICE DOES NOT COMPLY WITH 21 CFR 1040.

USE ONLY AS COMPONENT.

The limited warranty (on page 23) is void if the following

considerations are not adhered to when integrating the

IS4800 series scan engine into a system.

Grounding

If the scan engine is going to be installed in a grounded host:

•Use an insulator between the engine chassis and host. The die-cast

engine chassis is at +Vcc.

•Use shoulder washers to isolate the screws from the host if the mounting

screws are metallic.

Magnetic Sensitivity

The scan engine can be negatively affected by magnetic fields:

•Use only non-magnetic screws and locating pins.

•Do not mount the engine within 1.00" of any magnetic materials.

Electrostatic Discharge (ESD) Cautions

The scan engine has exposed electrical components.

•DO NOT touch the leads of the Visible Laser Diode (VLD) or other

components.

•ALWAYS use grounding wrist straps and a grounded work area when

handling the engine.

•Mount the engine in a housing that is designed for ESD protection and

stray electric fields.

ESD has the ability to modify the electrical characteristics of a

semiconductor device, possibly degrading or even destroying the

device. ESD also has the potential to upset the normal operation

of an electronic system, causing equipment malfunction or failure.

Printed Circuit Board (PCB) Component Clearance

WARNING: When designing the IS4800 into the final product, be sure to eliminate

all possible means of shorting Resistors R3 and R25 in the IS4800.

A short could enable the scan engine to emit Class 3R radiation. Any

CDRH filing will require a disclosure of the design ensuring a method

to mitigate a potential short.

Figure 5. IS4800 PCB Clearence Warning

Airborne Contaminants and Foreign Materials

The scan engine has very sensitive miniature electrical and optical

components that must be protected from airborne contaminants and foreign

materials. In order to prevent permanently damaging the scan engine and

voiding the limited warranty (on page 23), the scan engine enclosure must be:

•Sealed to prevent infiltration by airborne contaminants and foreign

materials such as dust, dirt, smoke, and smog.

•Sealed to protect against water, humidity and be non-condensing.

Beam Clearance

•Keep the scan engine’s beam sweep free from obstructions. For detailed

information on the exit beam angle and location please refer to Exit Beam

Specifications on page 4.

•A dark matte-finish on the internal walls of the housing can be utilized to

avoid internal beam reflections.
