Page 7: Chapter 1 Introduction
Chapter 1 Introduction Overview The EM3296 OEM scan engines, armed with the Newland patented , a computerized image recognition system, bring about a new era of 2D barcode scan engines. The EM3296’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 EM3296 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 EM3296 must be sufficiently enclosed to prevent dust particles from gathering on the imager, lens and circuit board. -
Page 9: Installation Orientation
Avoid wrapping the EM3296 with thermal insulation materials such as rubber. Installation Orientation The EM3296 has two threaded mounting holes for machine screws in its bottom. The following figure illustrates a front view of the EM3296 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 farthest surface of the window. -
Page 11: Scratch Resistance And Coating
Scratch Resistance and Coating Scratch on the window can greatly reduce engine performance. 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 illumination envelope shown below. -
Page 12: Ambient Light
Vertical: Ambient Light The EM3296 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 EM3296 has no lasers. It uses LEDs to produce 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 15: Chapter 3 Electrical Specifications
Chapter 3 Electrical Specifications Power Supply Do not power up the EM3296 until it is properly connected. Be sure the power is cut off before connecting a cable to or disconnecting a 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 on the EM3296. PIN# Signal 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 EM3296 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 EM3296 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 EM3296 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 EM3296’s TTL-232 interface supports baud rates from 1200bps to 115200bps; it does not support hardware flow control. -
Page 22: Control Interfaces
Control Interfaces Reset Driving the Reset pin (PIN 11) on the host interface connector low for 100us-500us can reset the EM3296. 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 EM3296 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 EM3296 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 25: Chapter 5 Development Tools
Chapter 5 Development Tools The EVK is provided to help users to test and evaluate the EM3296, which contains beeper & beeper driver circuit, LED & LED driver circuit, and trigger & reset buttons, TTL-232 to RS-232 converter & TTL-232 to USB converter, RS-232 & USB interfaces, etc. The EM3296 can be connected to the EVK via a 12-pin FFC cable type 1 (contacts on the same side). - Page 26 Newland Auto-ID Tech.
