Specifications Manual
1. Abstract
This document provides specifications of the MSL 2000 laser scan engine.
2. Overview
The MSL 2000 (hereafter called “the scan engine”) is an undecoded compact laser barcode
scan engine that can be installed in various handheld products such as portable terminals.
When scanning a target at the minimum decode distance, this scan engine can scan up to
44 mm wide at an angle of 44°. The use of a short-wavelength red laser beam enhances
the visibility of the laser beam when scanning barcodes.
This scan engine scans barcodes using laser light and outputs those barcode images as a
logic level signal (hereinafter called the “signal”). This scan engine also outputs timing
waveforms (signals) synchronized with scanning. Such timing waveforms (signals) are
hereinafter referred to as “TIMING”. This scan engine can be turned on and off via an
external input signal, “POWER EN”. The laser light emission of this scan engine can be
controlled via an external input signal, “LASER EN”.

This scan engine is compliant with RoHS.
