In addition to its RFID system with all-metal components for particularly demanding environments (low-frequency technology), Contrinex has now also developed an RFID product range which works according to high-frequency technology (13.56 MHz). This new standard system allows for the integration of all tags complying with the requirements of the ISO/IEC 15693 standard. It is moreover particularly user friendly, due to the fact that its read/write modules can be connected directly to an RS485 field bus. In this way, a network of up to 253 read/write modules may be built up. By means of a USB adaptor, up to 10 read/write modules can be directly addressed physically from a control console. The physical address of a specific read/write module is determined by means of a selector built into the device. And by programming each read/write module separately, up to 253 addresses can be controlled. To ensure easy use of the system, a demo programme provides the user with an introduction to the system.
