  • Page 7: Chapter 1 Introduction

    Chapter 1 Introduction Overview The EM1395-LD OEM scan engine, armed with the Newland patented , a computerized image recognition system, brings about a new era of 1D barcode scan engines. The EM1395-LD’s 1D barcode decoder chip ingeniously blends technology and advanced chip design &...
  • Page 8: Chapter 2 Installation

    Chapter 2 Installation General Requirements ESD protection has been taken into account when designing the EM1395-LD and the engine is shipped in ESD safe packaging. Always exercise care when handling the engine outside its package. Be sure grounding wrist straps and properly grounded work areas are used. Dust and Dirt The EM1395-LD must be sufficiently enclosed to prevent dust particles from gathering on the imager, lens and circuit board.
  • Page 9: Installation Orientation

    Installation Orientation The following figure illustrates a front view of the EM1395-LD after correct installation. From left to right in the figure are lens and illumination (aiming), with decoder board on the top and mounting holes on the bottom. Optics Window Placement The window should be positioned properly to let the illumination and aiming beams pass through as much as possible and no reflections back into the engine (reflections can degrade the reading performance).
  • Page 10: Window Material And Color

    Window Material and Color Wavelength of illumination beam and CIS’s responsiveness (mainly to wavelengths of red light) should be taken into consideration when choosing window material and color, to achieve the possible highest spectral transmission, lowest haze level and homogeneous refractive index. It is suggested to use PMMA or optical glass with spectral transmittance over 90% and haze less than 1%.
  • Page 11: Window Size

    Window Size The window must not block the field of view and should be sized to accommodate the illumination envelope shown below. Illumination Envelope FOV Envelope Illumination Envelope Ambient Light The EM1395-LD shows better performance with ambient light and it is well able to handle the flicker in fluorescent lights using 50-60Hz AC power.
  • Page 12: Mounting

    Mounting The illustrations below show the mechanical mounting dimensions for the EM1395-LD. The structural design should leave some space between components and reserve enough room for the FFC cable. Front View (unit: mm) Top View (unit: mm) Bottom View (unit: mm)

    Chapter 3 Electrical Specifications Power Supply Do not power up the EM1395-LD until it is properly connected. Be sure the power is cut off before connecting a flexible cable to or disconnecting a flexible cable from the host interface connector. Hot-plugging could damage the engine.

    Chapter 4 Interfaces Host Interface Connector The following table lists the pin functions of the 12-pin host interface connector on the EM1395-LD. PIN# Signal Name Function Not connected. 3.3V power supply. Power-supply ground. TTL level 232 receive data. TTL level 232 transmit data. USB_D- USB_D- differential data signal.
  • Page 16: Dimensions Of The Host Interface Connector (Unit: Mm)

    Dimensions of the Host Interface Connector (unit: mm) The engine uses a 12-pin ZIF socket (bottom contact, model: 10051922-1210ELF/ 10051922-1210EHLF) manufactured by FCI. The socket can be connected to a host device with an FFC cable.
  • Page 17: Communication Interface

    USB COM Port Emulation: The USB port on the host device is emulated as a serial port with the same data transmission and configuration as a real serial port. A driver is required.  USB DataPipe: This protocol is defined by Newland. A driver is required when using this protocol to communicate with scanner. ...
  • Page 18: Trigger

    bit. Trigger Driving the nTrig pin (PIN 12) on the host interface connector low for over 10ms causes the EM1395-LD to start a scan and decode session. If barcode is decoded, the EM1395-LD waits for the voltage at the nTrig pin to turn high (or the trigger to be released) after sending the data to the Host. If the trigger is released during a scan attempt, the EM1395-LD immediately stops decoding.
  • Page 19: Beeper

    Beeper The EM1395-LD provides a pin (Buzz, PIN 9) on the host interface connector that provides a PWM output to an external driver circuit for generating audible feedback to the user to indicate statuses like power up or good decode. The PWM output is not strong enough to drive a beeper, thus a beeper driver circuit is needed.
  • Page 20: Good Read Led

    Good Read LED The EM1395-LD provides a pin (LED, PIN 10) on the host interface connector that can be used by an external driver circuit to drive an LED to indicate a Good Read status. When a good read occurs, the LED pin produces a high level output for about 300ms, then the signal is back to a low level.
  • Page 21: Chapter 5 Development Tools

    Chapter 5 Development Tools The EVK is provided to help users to test and evaluate the EM1395-LD, which contains beeper & beeper driver circuit, LED & LED driver circuit, trigger & reset buttons, TTL-232 to RS-232 converter & TTL-232 to USB converter, RS-232 & USB interfaces, etc. The EM1395-LD can be connected to the EVK via a 12-pin FFC cable type 1 (contacts on the same side).
