Page 4: Introduction
Introduction The RT214D is an area image engine for barcode reading. It includes an illumination LED and an aiming LED. The RT214D contains: a CMOS image sensor and its lens an LED based illumination system • an LED aiming system •... -
Page 5: Illumination
Aimer The RT214D contains a red LED aimer to help the user to easily position the target barcode within the engine’s field of view to increase scan efficiency. The aiming pattern can be turned On or Off. It is advisable to turn it on when scanning barcodes in regular circumstances. -
Page 6: Introduction
Dust and Dirt The RT214D 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 7: Thermal Considerations
Thermal Considerations Electronic components in the RT214D will generate heat during the course of their operation. Operating the RT214D 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 RT214D. -
Page 8: Mounting
Mounting The illustrations below show the mechanical mounting dimensions (unit: mm) for the RT214D. Note: Tolerance of dimension is ±0.15mm. Two m1.4 screw holes are reserved for installation, and the depth of the screws into the shell shall not exceed 2mm. -
Page 9: Housing Design
It is recommended to use baffles or matte-finished dark internal housing colors. Optics The RT214D 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 of the engine). -

Figure 2-2 Table 2-2 Distance from the front of the engine housing (b) Minimum Angle (Tilted Window) 10mm 15mm 20mm Uncoated, minimum window positive tilt (+w) 35° 30° 28° Uncoated, minimum window negative tilt (-w) Window Material and Color Window material must be clear. Use only cell-cast plastics or optical glass. PMMA and chemically tempered glass are recommended. -
Page 11: Coatings And Scratch Resistance
Coatings and Scratch Resistance Scratch on the window can greatly reduce the performance of the RT214D. It is suggested to use abrasion resistant window material or coating. The following introduces two commonly-used types of coatings: •... -

Eye Safety The RT214D 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 13: Power Supply
Power Supply Do not power up the RT214D 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. - Page 14 500mA. Ensure that Rdc of the cable is controlled within 0.35Ω by shortening FPC cable, increasing power line and ground line width, etc. Avoid using long cables to connect the RT214D. Power consumption will result in abnormal function.
