Chapter 1 Introduction
Overview
TM
The EM1365-LS OEM scan engine, armed with the Newland patented , a computerized image
recognition system, brings about a new era of 1D barcode scan engines.
The EM1365-LS’s 1D barcode decoder chip ingeniously blends technology and advanced chip
design & manufacturing, which significantly simplifies application design and delivers superior
performance and solid reliability with low power consumption.
The EM1365-LS supports EAN-13, EAN-8, UPC-A, UPC-E, ISSN, ISBN, Codabar, Code 128, Code 93,
ITF-6, ITF-14, Interleaved 2 of 5, Industrial 2 of 5, Standard 2 of 5, Matrix 2 of 5, GS1 Databar, Code 39,
Code 11, MSI-Plessey, Plessey.
Illumination
The EM1365-LS uses a laser diode (648nm~660nm) for illumination, making it possible to scan barcodes
even in complete darkness. The illumination can be programmed On or Off.
Aimer
The EM1365-LS employs laser aimer to help the user to easily position the target barcode within the
engine’s field of view to increase scan efficiency.

Chapter 2 Installation
General Requirements
ESD
ESD protection has been taken into account when designing the EM1365-LS 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 EM1365-LS must be sufficiently enclosed to prevent dust particles from gathering on the imager, lens
and circuit board. Dust and other external contaminants will eventually degrade the engine’s
performance.
Ambient Environment
The following environmental requirements should be met to ensure good performance of the EM1365-LS:
Operating Temperature
-20℃~ 60℃
Storage Temperature
-40℃~ 85℃
Humidity
5% ~ 95% (non-condensing)
Thermal Considerations
Electronic components in the EM1365-LS will generate heat during the course of their operation.
Operating the EM1365-LS in continuous mode for an extended period may cause temperatures to rise on
CIS and decoder chip. Overheating can degrade image quality and affect scanning performance. Given
that, the following precautions should be taken into consideration when integrating the EM1365-LS.
Reserve sufficient space for good air circulation in the design.
Avoid wrapping the EM1365-LS with thermal insulation materials such as rubber.

Installation Orientation
The following figure illustrates a front view of the EM1365-LS after correct installation. From left to right in
the figure are illumination, lens and 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).
The window should be mounted close to the front of the engine (parallel). The maximum distance is
measured from the front of the engine housing to the farthest surface of the window. In order to reach
better reading performance, the distance from the front of the engine housing to the furthest surface of
the window should not exceed 3mm and the distance from the front of the engine housing to the nearest
surface of the window should not exceed 2mm.
If the window is required to be in a tilted position, the above distance requirements should be met and tilt
angle should ensure no reflections back into the lens.

Window Material and Color
Wavelengths of illumination and aiming beams 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%.
Whether to use an anti-reflection coating or not depends on the material and application needs.
Scratch Resistance and Coating
Scratch on the window can greatly reduce engine performance. It is recommended to use abrasion
resistant window material or coating.
Window Size
The window must not block the field of view and should be sized to accommodate the aiming and
illumination envelopes shown below.

Laser Aimer Envelope 38°
FOV Envelope 40°
Illumination Envelope 26°
Illumination Envelope 3°

6
Ambient Light
The EM1365-LS shows better performance with ambient light and it is well able to handle the flicker in
fluorescent lights using 50-60Hz AC power. However, high-frequency pulsed light can result in
performance degradation.
Eye Safety
The EM1365-LS uses a laser diode to form a bright, intuitive aiming aid. It is hazardous to stare into the
laser beam.

Mounting
The illustrations below show the mechanical mounting dimensions for the EM1365-LS. The structural
design should leave some space between components.

Chapter 3 Electrical Specifications
Power Supply
Do not power up the EM1365-LS 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.
Unstable power supply or sharp voltage drops or unreasonably short interval between power-ons may
lead to unstable performance of the engine. Do not resupply the power immediately after cutting it off. The
minimum interval must exceed 500ms.
The EM1365-LS itself does not provide a power switch. Users can switch the engine off by cutting off the
power.
The EM1365-LS’s start-up time is less than 200ms.
Ripple Noise
Image sensor and decoder chip are directly fed by the input power of EM1365-LS. To ensure the image
quality, a power supply with low ripple noise is needed.
Acceptable ripple range (peak-to-peak) : ≤100mV (≤50mV recommended).

Dimensions of the Host Interface Connector (unit: mm)
The scan engine uses a 12-pin ZIF socket (bottom contact). The socket can be connected to a host
device with an FFC cable.
FFC Cable (unit: mm)
A 12-pin FFC cable can be used to connect the EM1365-LS to a host device. The cable design must be
consistent with the specifications shown below. Use reinforcement material for the connectors on the
cable and reduce cable impedance for reliable connection and stable performance.

13
Communication Interface
The EM1365-LS can communicate with the host device through one of the following interfaces:
TTL-232: This interface, in most cases, does not require any hardware modifications to existing
platforms. However, for those requiring RS-232, a TTL-232 to RS-232 conversion circuit is needed.
USB HID-KBW: Based on USB connection, the engine’s transmission is simulated as USB keyboard
input. It works on a Plug and Play basis and no driver is required.
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.
HID-POS: HID-POS does not require a custom driver. However, an HID interface on Windows 98
does. All HID interfaces employ standard driver provided by the operating system.
The EM1365-LS’s serial port supports baud rates from 1200bps to 115200bps; it does not support
hardware or software flow control. Its default settings are 9600bps, 8 data bits, no parity check and1 stop
bit.

14
Trigger
Driving the nTrig pin (PIN 12) on the host interface connector low for over 10ms causes the EM1365-LS
to start a scan and decode session. If barcode is decoded, the EM1365-LS 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 EM1365-LS immediately stops decoding.
Next decode session does not happen until the EM1365-LS receives active trigger signal (driving the
nTrig pin low) again.
As a decode session involves image capture, barcode decoding and other steps, it is suggested that the
minimum interval between two triggers should exceed 50ms.
The following trigger circuit is provided for reference.
