Page 9: Chapter 1 Getting Started
Chapter 1 Getting Started Introduction The EM27 is an area image engine for barcode reading. It includes four illumination LEDs and a 8-pin box connector. LED Compliance Statement The EM27 complies with IEC 62471:2006 for LED safety. The EM27 contains: •... -
Page 10: Illumination
Buzzer The EM27 provides a buzzer to indicate power-on and good read statuses. The Power On Beep and Good Read Beep can be programmed On or Off, and the Good Read Beep Volume, Duration and Frequency are also programmable by the user. -
Page 11: Chapter 2 Installation
Dust and Dirt The EM27 must be sufficiently enclosed to prevent dust particles from gathering on the lens and circuit board. Dust and other external contaminants will eventually degrade the engine’s performance. -
Page 12: Thermal Considerations
Thermal Considerations Electronic components in the EM27 will generate heat during the course of their operation. Operating the EM27 in continuous mode for an extended period may cause temperatures to rise on CPU, CIS, LEDs, etc. Overheating can degrade image quality and affect scanning performance. Given that, the following precautions should be taken into consideration when integrating the EM27. -
Page 13: Mounting
Mounting The illustrations below show the mechanical mounting dimensions (unit: mm) for the EM27. 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: Optics
Optics The EM27 uses a sophisticated optical system. An improperly designed internal housing or improper selection of window material can degrade the engine’s performance. 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). -
Page 15: Coatings And Scratch Resistance
Coatings and Scratch Resistance Scratch on the window can greatly reduce the performance of the EM27. It is suggested to use abrasion resistant window material or coating. The following introduces two commonly-used types of coatings: •... -
