Page 9: Chapter 1 Getting Started
Chapter 1 Getting Started Introduction The EM20-M37 is an area image engine for barcode reading. It includes an LED illumination system. LED Compliance Statement The EM20-M37 complies with IEC 62471:2006 for LED safety. The EM20-M37 includes: • a CMOS image sensor and its lens •... -
Page 10: Illumination
Illumination The EM20-M37 has 4 white LEDs for supplementary lighting, making it possible to scan barcodes even in complete darkness. The illumination can be turned On or Off. -
Page 11: Chapter 2 Installation
Chapter 2 Installation Introduction This chapter explains how to install the EM20-M37, 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-M37 will generate heat during the course of their operation. Operating the EM20-M37 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-M37. -
Page 13: Mounting
Mounting The illustrations below show the mechanical mounting dimensions for the EM20-M37. The structural design should leave some space between components. Front View (Unit: mm) Figure 2-2 Side View (Unit: mm) Figure 2-3 Rear View (Unit: mm) Figure 2-4... -
Page 14: Top View (Unit: Mm)
Top View (Unit: mm) Figure 2-5 Optics Window Placement The window should be positioned properly to let the illumination beam pass through as much as possible and no reflections back into the engine (reflections can degrade the reading performance of the engine). The window should be mounted as close to the front of the engine (parallel) as possible. -
Page 15: Window Material And Color
Window Material and Color Window material must be clear. Use only cell-cast plastics or optical glass. PMMA, ADC and chemically tempered glass are recommended. Window material selected for the engine should meet or exceed the specifications specified in Table 2-2. •... -
Page 16: Window Size
Both tempered glass and plastic windows can be AR coated. However, it is easier and more cost-effective to put an AR coating on the glass than on the plastic. The AR coating specifications below should be met when using an AR coated window. Single side AR coating: 92% minimum transmittance within spectrum range from 420 nm to 730 nm. -
Page 17: Roll, Skew And Pitch
Three different reading angles, roll, skew and pitch are illustrated in Figure 2-9. 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 2-9 Ambient Light The EM20-M37 shows better performance with ambient light. -
Page 18: Chapter 3 Electrical Specifications
Chapter 3 Electrical Specifications Power Supply Do not power up the EM20-M37 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. Unstable power supply or sharp voltage drops or unreasonably short interval between power-ons may lead to unstable performance of the engine. -

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-M37 consists of 12-pin FPC connector and 5-pin box connector: • 12-pin FPC connector can be used as TTL-232 interface or USB interface. • 5-pin box connector can only be used as standard USB interface. The figure below illustrates the positions of 12-pin FPC connector and 5-pin box connector on the EM20-M37’s decoder board, as well as the pin layout of the FPC connector. -
