Page 5: Chapter 1 Introduction
Chapter 1 Introduction About EM2037 EM2037 is an embedded 2D Barcode Scan Engine with CMOS technology and Newland`s . It can read barcodes on various carriers like paper and magnetic cards and is suitable to be integrated into various OEM devices including handheld scanners, PDA, kiosks, etc. -
Page 6: Chapter 2 Installation
Chapter 2 Installation General Requirements ESD Precautions ESD has been taken into consideration during the design of EM2037 and the engine is shipped in ESD safe packaging. Use care when handling the engine outside its package. Be sure grounding wrist straps and properly grounded work areas are used. -
Page 7: Optics
Figure 2-1 Optics Window Placement The window functions as an isolation wall in front of EM2037 to separate the engine from other parts of the entire device. Meanwhile the window placement should ensure that the illumination and aiming beams can come out and no reflection into the engine, otherwise the reading performance might be affected. -

clear and has even refraction. It is suggested to use PMMA or optical glass with transmission rate over 90% and vagueness rate less than 1%. Whether coated or not depends on materials and application demands. Abrasion-resistant and Coating Scratch on window will severely reduce the reading performance. It is suggested to use high-abrasion window material or use abrasion-resistant coating to prevent scratch and abrasion. - Page 9 Figure 2-4 Longitudinal Section Optical Diagram of 37.5° Lens Figure 2-5 Crosswise Section Figure 2-6 Longitudinal Section Optical Diagram of 42° Lens...

Figure 2-7 Crosswise Section Figure 2-8 Longitudinal Section Ambient Light EM2037 might show better performance with ambient light. For high-frequency impulse light, however, the reading might be interfered. Eye Safety EM2037 adopts LEDs instead of laser for aiming and illumination. Such LEDs are safe to eyes in normal circumstances. -

Chapter 3 Electrical Power Supply Do not input power until the engine is connected properly, otherwise the components inside the engine might be damaged. Be sure the power is cut off before connecting or disconnecting the flexible flat cable. Unstable power supply or sharp voltage drop might make the engine under unstable state. Wait at least for 2s before supplying power again. -
Page 16: Chapter 4 Interfaces
Chapter 4 Interfaces Interface Definition The interface of EM2037 consists of 12 PIN-FPC and Micro USB: 12 PIN-FPC can either be TTL232 or USB form. Note: One product model supports either TTL-232 or USB form. Micro USB can only be used as standard USB interface. The location of 12 PIN-FPC connector and Micro USB connector are marked in below illustation. -
