| There is a wide range of readers with capabilities that are designed to suit differing application requirements. In general terms, a reader comprises a microprocessor-controlled RF transmitter and receiver. The reader is controlled through an interface, typically a serial port, the characteristics of which will vary according to application (RS232, USB, Ethernet, etc.). The amount of memory a reader will contain for data and event logging, etc., also varies substantially. These can range from an elementary device with minimal complexity, designed for embedded applications (such as inside a Zebra printer/encoder), to a sophisticated reader used in high-performance situations (such as on a high-speed conveyor). |
