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.

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.

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.
