Specifications Manual

1. Abstract

This manual provides specifications for the MDL 2000 laser scan engine.

2. Overview

The MDL 2000 laser scan engine is a compact laser barcode scan engine that can be installed
in various handheld products, such as a cellular terminal. When scanning a target at the closest
point, it has the ability to scan up to 44 mm wide at an angle of 44°. The use of a short­wavelength red laser beam enhances visibility when scanning lines.

A decoder is built into the MDL 2000 that enables this scan engine to decode barcodes after
scanning and output the information using serial communication.

The MDL 2000 complies with the Restriction of Hazardous Substances (RoHS).

When in low power mode, the state of operation changes automatically from “Power On” to
“Low Power”.

If there is a transition to the “IDLE” state by enabling “CTS ON” or “WAKE ON” in “Low Power
Mode,” it will automatically go back to the “Low Power” state in a second unless transitioning to
another mode.
