Page 7: Chapter 1 Introduction
Chapter 1 Introduction Overview The NLS-EM3396 V2 OEM scan engine (hereinafter referred to as “the EM3396 V2” or “the engine”), armed with the Newland patented , a computerized image recognition system, brings about a new era of 2D barcode scan engines. -
Page 8: Chapter 2 Installation
Chapter 2 Installation General Requirements ESD protection has been taken into account when designing the EM3396 V2 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 EM3396 V2 must be sufficiently enclosed to prevent dust particles from gathering on the lens, circuit boards and LEDs. -
Page 9: Ambient Environment
Ambient Environment The following environmental requirements should be met to ensure good performance of the EM3396 V2: Operating Temperature -20℃ to 55℃ Storage Temperature -40℃ to 70℃ Humidity 5% ~ 95% (non-condensing) Thermal Considerations Electronic components in the EM3396 V2 will generate heat during the course of their operation. Operating the EM3396 V2 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: Window Size
Window Size The window must not block the field of view and should be sized to accommodate the aiming and illumination envelopes shown below. Horizontal:... -
Page 12: Ambient Light
Vertical: Ambient Light The EM3396 V2 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 V2 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 13: Mounting (Unit: Mm)
Mounting (unit: mm) The illustrations below show the mechanical mounting dimensions for the EM3396 V2. The structural design should leave some space between components. -
Page 14: Chapter 3 Electrical Specifications
Chapter 3 Electrical Specifications Power Supply Do not power up the EM3396 V2 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. -

Page 16: I/O Voltage
I/O Voltage VDD=3.3 V, GND =0 V, T=25° C Parameter Condition Minimum Maximum Unit except for nTrig pin except for nTrig pin only nTrig pin 2.2 (VDD-1.1) only nTrig pin 2.9（VDD-0.4） Iol= 4mA~16mA Ioh= 4mA~16mA The high and low level thresholds of nTrig are related to the external power supply voltage VDD. The input low level VIL of nTrig should not be higher than VDD-1.1, and the input high level VIH of nTrig should not be lower than VDD-0.4. -
Page 17: Timing Sequence
Timing Sequence Power Up Timing Sequence 400ms 50ms 250ms 100ms USB_D+ USB_D- nTRIG nRST In the diagram above, it takes A+B+C (about 400ms) for the engine to power up: A is bootloader execution time (100ms), B is kernel boot time (50ms) and C is decoding chip initialization time(250ms). Waken-up duration from the deep low consumption mode is 300ms. -
Page 18: Power Down Timing Sequence
Power Down Timing Sequence USB_D+ USB_D- nTRIG nRST Note: When powered down, ensure that levels of TXD, RXD, USB_D+, USB_D-, nTRIG and nRST signals are kept low in addition to cutting off the input power, otherwise it will lead to abnormal power-on function. -

Chapter 4 Interfaces Host Interface Connector The following table lists the pin functions of the 12-pin host interface connector of the EM3396 V2. 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 (optional) USB_D+... -
Page 20: Dimensions Of The Host Interface Connector (Unit: Mm)
Dimensions of the Host Interface Connector (unit: mm) The EM3396 V2 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 21: Ffc Cable (Unit: Mm)
FFC Cable (unit: mm) A 12-pin FFC cable can be used to connect the EM3396 V2 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 22: Communication Interfaces
Communication Interfaces The EM3396 V2 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 V2’s TTL-232 interface supports baud rates from 1200bps to 115200bps; it does not support hardware flow control. -
Page 23: Control Interface
Control Interface Reset Driving the Reset pin (PIN 11) on the host interface connector low for 100us-500us can reset the EM3396 V2. However, do not reset the engine at unreasonably short intervals. The minimum interval between resets must exceed 2 seconds. Trigger The circuit below is used to provide the engine with a signal to trigger a scan and decode session. -
Page 24: Beeper
Beeper The EM3396 V2 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. -
Page 25: Good Read Led
Good Read LED The EM3396 V2 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. -
