  • Page 9: Chapter 1 Getting Started

    Chapter 1 Getting Started Introduction The EM20-80 is an area image engine for barcode reading. It includes eight illumination LEDs, two Good Read LEDs, one 12-pin FPC connector and two 4-pin box connectors. LED Compliance Statement The EM20-80 complies with IEC 62471:2006 for LED safety. The EM20-80 contains: •...
  • Page 10: Illumination

    The 12-pin FPC connector/4-pin box connectors on the engine can be connected to a host device with an appropriate cable. Illumination The EM20-80 has eight LEDs for supplementary lighting, making it possible to scan barcodes even in complete darkness. The illumination can be programmed On or Off. Good Read LED The EM20-80 provides two green LEDs to indicate good read status.
  • Page 11: Chapter 2 Installation

    Chapter 2 Installation Introduction This chapter explains how to install the EM20-80, including general requirements, housing design, and physical and optical information. △ Caution: Do not touch the imaging lens when installing the engine. Be careful not to leave fingerprints on the lens. !...
  • Page 12: Thermal Considerations

    Thermal Considerations Electronic components in the EM20-80 will generate heat during the course of their operation. Operating the EM20-80 in continuous mode for an extended period may cause temperatures to rise on CPU, CIS, LEDs, DC/DC, etc. Overheating can degrade image quality and affect scanning performance. Given that, the following precautions should be taken into consideration when integrating the EM20-80.
  • Page 13: Housing Design

    Figure 2-1 Housing Design ※ Note: Conduct an optical analysis for the housing design to ensure optimal scanning and imaging performance. Housing design should make sure that internal reflections from the aiming and illumination system are not directed back to the engine.
  • Page 14: Window Placement

    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 directly against the front of the engine (parallel, a=0). Figure 2-2 Window Material and Color Window material must be clear.

    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: Figure 2-3 Vertical: Figure 2-4...
  • Page 17: Roll, Skew And Pitch

    Three different reading angles, roll, skew and pitch are illustrated in Figure 2-7. Roll refers to rotation around the Z axis, skew to rotation around the X axis and pitch to rotation around the Y axis. For the engine’s technical specifications, please visit the Newland website or contact your dealer. Figure 2-5 Ambient Light The EM20-80 shows better performance with ambient light.
  • Page 18: Chapter 3 Electrical Specifications

    Chapter 3 Electrical Specifications Power Supply Do not power up the EM20-80 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. Make sure that the FFC cable is horizontally inserted into the connector when installing the cable to connect the engine’s 12-pin connector to the host.

In the diagram above, it takes A+B (about 940ms) for the engine to power up: A is reset time (about 280ms), B is time needed to start the engine (including bootloader execution, kernel boot and decoding chip initialization).
  • Page 20: Chapter 4 Interfaces

    Chapter 4 Interfaces Interface Pinouts The physical interface of the EM20-80 consists of a 12-pin FPC connector and two 4-pin box connectors: • 12-pin FPC connector can be used as TTL-232 interface or USB interface. • One 4-pin box connector can be used as standard USB interface and the other as RS-232 interface. Figure 4-1 12-pin FPC Connector The following table lists the pin functions of the 12-pin FPC connector.

    ※ I = Input; O = Output; od = Open Drain; ※ 1 This external trigger signal can be either level trigger or pulse trigger. Level trigger: A trigger pull (i.e. driving the nTRIG pin low for over 10ms) activates a decode session. The decode session continues until a barcode is decoded or the trigger is released.
