2 Introduction The RT214C is an area image engine for barcode reading. It includes an illumination LED and an aiming LED. LED Compliance Statement The RT214C complies with IEC 62471:2006 for LED safety. The RT214C contains: •a CMOS image sensor and its lens •an LED based illumination system •an LED aiming system Figure 1-1 System Block Diagram

3 Illumination The RT214C has a white LED for supplementary lighting, making it possible to scan barcodes even in complete darkness. The illumination can be programmed On or Off. Aimer The RT214C 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. For applications in the background of different materials and colors or in the strong light or backlight environment, it is advised to turn off the aimer.
