Page 7: Chapter 1 Introduction
Chapter 1 Introduction Overview The NLS-EM3396 OEM scan engine (hereinafter referred to as “the EM3396” or “the engine”), armed with the Newland patented , a computerized image recognition system, brings about a new era of 2D barcode scan engines. The EM3396’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 EM3396 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. Note: The EM3396’s laser diode (circled in the figure below) is ESD sensitive and rated Class 1A Human Body Model (HBM) 270V, thus ESD protection measures, such as the ones mentioned above, must be taken when handling or installing the EM3396 to avoid damage to the laser diode. -
Page 9: Ambient Environment
Ambient Environment The following environmental requirements should be met to ensure good performance of the EM3396: Operating Temperature -20℃ to 55℃ Storage Temperature -40℃ to 70℃ Humidity 5% ~ 95% (non-condensing) Thermal Considerations Electronic components in the EM3396 will generate heat during the course of their operation. Operating the EM3396 continuously for an extended period may cause temperatures to rise on CIS and decoder chip. -
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 farthest 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 EM3396. 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: Ambient Light
Vertical: Ambient Light The EM3396 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 EM3396 uses red LEDs to create illumination beam. 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 15: Chapter 3 Electrical Specifications
Chapter 3 Electrical Specifications Power Supply Do not power up the EM3396 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 17: 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 18: 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 EM3396. 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 19: Dimensions Of The Host Interface Connector (Unit: Mm)
Dimensions of the Host Interface Connector (unit: mm) The EM3396 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 a FFC cable. -
Page 20: Ffc Cable (Unit: Mm)
FFC Cable (unit: mm) A 12-pin FFC cable can be used to connect the EM3396 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 21: Communication Interfaces
Communication Interfaces The EM3396 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 EM3396’s TTL-232 interface supports baud rates from 1200bps to 115200bps; it does not support hardware flow control. -
Page 22: Control Interface
Control Interface Reset Driving the Reset pin (PIN 11) on the host interface connector low for 100us-500us can reset the EM3396. However, do not reset the engine at unreasonably short intervals. The minimum interval between resets must exceed 2 seconds. Trigger Driving the nTrig... -
Page 23: Beeper
Beeper The EM3396 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 24: Good Read Led
Good Read LED The EM3396 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, and then the signal is back to a low level. -
