MDI-3100-HD

Specifications Manual

1. Abstract

This manual provides specifications for the MDI-3100-HD imager scan engine.

2. Overview

The MDI-3100-HD is an imager scan engine with an integrated decoder, which enables high speed scanning of high resolution linear (1D) and 2D symbologies at close range. Main features of the MDI-3100-HD are as follows:

・ High-speed reading

Extremely high-speed performance ensures stress free scanning and fast response without being affected by hand movement and light conditions.

・ Integrated decoder

The MDI-3100 with its combined camera and decoder module offers an ultra-miniature module.

The compact design enables easy installation.

・ Low power consumption

Power consumption in operating, standby and low power states has been drastically reduced. Various power saving settings can be configured in low power mode.

・ LED aiming

LED's provide a crisp green line for clear and consistent targeting.

・ RoHS compliance

The MDI-3100 is a RoHS compliant product, which is declared by Optoelectronics Co., Ltd.

Note: Refer to “Serial Interface / Software Specifications” for supported codes and commands.

Note: The above shows the possibility of high speed decoding, but 100% decoding at high speed can not be guaranteed, since other factors can influence this capability. If high speed (>=1M/s) capability is required, then always run in-motion evaluation test along with image captures to determine if this product satisfies all requirements before a large purchase is made.

While this module is capable of high speed in-motion decoding by itself, other factors may be required in certain applications, such as:

• Eliminating all specular reflections

• Adding External Illumination

• Using an External Trigger signal (i.e. photoeye)

• Improving the quality and contrast of the bar code symbol.

(b) Image Data Acquisition

There shall be no excessive noise or misalignments in acquired images when sinusoidal electrical noise (50 Hz to 100 kHz, smaller than 20mVp-p) is added to the power supply line.

Note: There may be a case where the electrical noise affects the quality of captured images. The signal processing system of the MDI-3100 is especially designed for the purpose of scanning symbologies but not for the acquisition of image data. Therefore, the quality of captured images of the MDI-3100 may be lower than that of general digital cameras.

9.5. Vibration

There shall be no sign of malfunction of the MDI-3100 after the following vibration test.

Vibration Test: Increase the frequency of the vibration from 12Hz to 200Hz at accelerated velocity

Note: RoHS: The restriction of the use of certain hazardous substances in electrical and electronic equipment,

2002/95/EC.

13. Reliability

MTBF 53310 hours

Note: The reliability of the MDI-3100 is guaranteed as far as it is operated under normal operating conditions in the range of advised operating temperature and without excessive electrical or mechanical shock.

14. Precautions

• All workbenches, tools, measuring instruments and any part of human body, which have come into contact with MDI-3100, must undergo preliminary antistatic treatments.

• Do not touch the optical and electrical components. Hold it on the chassis when carrying the MDI-3100.

• Avoid handling the MDI-3100 in a dusty area. In case dust gets on the MDI-3100, gently blow it off with dry air. Direct contact of swabs and such on its optical part may cause deterioration of its performance.

• Do not drop the MDI-3100.
