Page 9: Chapter 1 Getting Started
Chapter 1 Getting Started Introduction The EM2037 is an area image engine for barcode reading. It includes an LED aiming system, and an LED illumination system. LED Compliance Statement The EM2037 complies with IEC 62471:2006 for LED safety. The EM2037 contains: •... -
Page 10: Illumination
Illumination The EM2037 has two red LEDs (wavelength: 612nm-624nm) for supplementary lighting, making it possible to scan barcodes even in complete darkness. The illumination can be turned On or Off. The EM2037 uses red LEDs for illumination, so the engine shows better reading performance on barcodes printed in non-red colors. For applications involving red barcodes, it is advised to turn off the engine’s illumination and use non-red supplementary lighting (such as green) instead. -
Page 11: Chapter 2 Installation
Chapter 2 Installation Introduction This chapter explains how to install the EM2037, 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 EM2037 will generate heat during the course of their operation. Operating the EM2037 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 EM2037. -

Page 17: Housing Design
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. The reflections from the housing or window can cause problems. For particular window tilt angles, the unwanted reflections can bounce off the top or bottom and reach the engine. -

Page 19: Coatings And Scratch Resistance
Pay extra attention to the wavefront distortion when using plastic materials. Plastic materials are not recommended for tilted windows; colored windows are not recommended if the engine is used to scan barcodes on moving objects. Coatings and Scratch Resistance Scratch on the window can greatly reduce the performance of the EM2037. It is suggested to use abrasion resistant window material or coating. - Page 20 • SR version Horizontal: Vertical: Figure 2-13...

Page 22: Roll, Skew And Pitch
Three different reading angles, roll, skew and pitch are illustrated in Figure 2-15. 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 2-15 Ambient Light The EM2037 shows better performance with ambient light. -
Page 23: Chapter 3 Electrical Specifications
Chapter 3 Electrical Specifications Power Supply Do not power up the EM2037 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. -
