Page 7: Chapter 1 Introduction
Chapter 1 Introduction Overview The EM2096 OEM scan engine, armed with the Newland patented , a computerized image recognition system, brings about a new era of 2D barcode scan engines. The EM2096’s 2D 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 EM2096 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 EM2096 must be sufficiently enclosed to prevent dust particles from gathering on the lens and circuit board. -
Page 9: Installation Orientation
Installation Orientation There are two threaded mounting holes in the bottom of the EM2096 for fastening the engine to a mounting surface with machine screws. The following figure illustrates a front view of the EM2096 after correct installation. -
Page 10: Optics
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 furthest surface of the window. -
Page 11: Scratch Resistance And Coating
Scratch Resistance and Coating Scratch on the window can greatly reduce the performance of the EM2096. It is suggested 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. - Page 12 Vertical:...

Page 13: Ambient Light
Ambient Light The EM2096 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 EM2096 has no lasers. It uses red LEDs to create illumination and aiming beams. The LEDs are bright, but testing has been done to demonstrate that the engine is safe for its intended application under normal usage conditions. - Page 14 Side View Top View...

Page 16: Connecting Imager To Decoder Board
Connecting Imager to Decoder Board The EM2096 consists of two separate components — an imager and a decoder board. The imager should be connected to the decoder board with a 21-pin FPC cable as shown below. Imager Decoder Board... -
Page 17: Chapter 3 Electrical Specifications
Chapter 3 Electrical Specifications Power Supply Do not power up the EM2096 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. -

Page 19: Timing Sequence
Timing Sequence The following diagram indicates the typical timing for the Power-up sequence of the engine. Notes: 1. In the diagram above, it takes about 400ms for the engine to power up: A - time needed to choose the boot mode; B - time needed to boot the kernel; C – time needed to initialize decoder chip. 2. -
Page 20: Chapter 4 Interfaces
Chapter 4 Interfaces Host Interface Connector The following table lists the pin functions of the 12-pin host interface connector of the EM2096. PIN# Signal Description 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 21: Dimensions Of The Host Interface Connector (Unit: Mm)
Dimensions of the Host Interface Connector (unit: mm) The EM2096 uses a 12-pin FPC ZIF socket (bottom contact, model: 10051922-1210EHLF) manufactured by FCI. The socket can be connected to a host device with an FFC cable. -
Page 22: Ffc Cable (Unit: Mm)
FFC Cable (unit: mm) A 12-pin FFC cable can be used to connect the EM2096 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. -
Page 23: Communication Interfaces
Communication Interfaces The EM2096 can communicate with the host device via its TTL-232 interface. This interface is applicable to most system architectures. For those requiring RS-232, a TTL-232 to RS-232 conversion circuit is needed. The EM2096’s TTL-232 interface supports baud rates from 1200bps to 115200bps; it does not support hardware flow control. -
Page 24: Control Interfaces
Control Interfaces Reset Driving the Reset pin (PIN 11) on the host interface connector low for 100us-500us can reset the EM2096. However, do not reset the engine at unreasonably short intervals. The minimum interval between resets must exceed 2 seconds. Trigger Driving the nTrig... -
Page 25: Beeper
Beeper The EM2096 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 read. The PWM output is not strong enough to drive a beeper, thus a beeper driver circuit is needed. The following beeper driver circuit is provided for reference. -
Page 26: Good Read Led
Good Read LED The EM2096 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 and then the signal is back to a low level. -
Page 27: Chapter 5 Development Tools
Chapter 5 Development Tools The EM2096’s development tools include both software and hardware and can be utilized for engine performance evaluation, application development and engine configuration. The EVK is provided to help users to test and evaluate the EM2096, which contains beeper & beeper driver circuit, LED &... - Page 28 Headquarters Fujian Newland Auto-ID Tech.
