Page 9: Chapter 1 Getting Started
Chapter 1 Getting Started Introduction The EM20-85 is an area image engine for barcode reading. It includes four illumination LEDs and a 12-pin FPC connector and a 8-pin box connector. LED Compliance Statement The EM20-85 complies with IEC 62471:2006 for LED safety. -
Page 10: Illumination
Buzzer The EM20-85 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... -
Page 11: Chapter 2 Installation
Dust and Dirt The EM20-85 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 EM20-85 will generate heat during the course of their operation. Operating the EM20-85 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 EM20-85. -
Page 13: Mounting
Mounting The illustrations below show the mechanical mounting dimensions (unit: mm) for the EM20-85. Figure 2-1... -
Page 14: Housing Design
It is recommended to use baffles or matte-finished dark internal housing colors. Optics The EM20-85 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: Window Material And Color
Window Material and Color Window material must be clear. Use only cell-cast plastics or optical glass. PMMA and chemically tempered glass are recommended. Window material selected for the engine should meet or exceed the specifications specified in Table 2-2. When using a clear plastic window, it is recommended to apply anti-reflection (AR) coating on it. •... -
Page 16: Coatings And Scratch Resistance
Coatings and Scratch Resistance Scratch on the window can greatly reduce the performance of the EM20-85. It is suggested to use abrasion resistant window material or coating. The following introduces two commonly-used types of coatings: • Anti-reflection coatings: Anti-reflection (AR) coatings can be applied to window surfaces to reduce reflected light from the window back into the engine. -
Page 17: Window Size
Window Size The window must not block the field of view and should be sized to accommodate the FOV envelopes shown below. Horizontal: Figure 2-3 Vertical: Figure 2-4... -
Page 18: Roll, Skew And Pitch
Eye Safety The EM20-85 has no lasers. It uses LEDs to produce illumination beam. The LEDs are bright, but testing has been done to demonstrate that the engine is safe for its intended application under normal usage conditions. However, the user should... -
Page 19: Chapter 3 Interfaces
Chapter 3 Interfaces Interface Pinouts The physical interface of the EM20-85 consists of a 8-pin box connector and a 12-pin FPC connector: • 8-pin box connector can be used as RS-232 interface or USB interface. • 12-pin FPC connector can be used as TTL-232 interface or USB interface. -
