DataMan 200 ID Reader is said to be the first image-based reader to feature full Ethernet connectivity in a package the size of a matchbox; is also the first to offer liquid lens technology. Ethernet connectivity provides real-time data and image transfer, and integration with plant controllers and information networks. Liquid lens technology is optional; adjusts the camera’s focus by applying an electrical charge to fluid within the lens. Autofocus is achieved with a single software command. Reportedly provides excellent depth of field and field-of-view range. Setup uses two laser aimers. Laser targets are seen through the entire depth of field. Supports a wide range of 1-D and 2-D codes, including UPC/EAN/JAN, Code 39, Code 128, Code 93, Interleaved 2 of 5, Data Matrix, QR Code, and micro QR Code.
