GAO RFID Inc. has rolled out its 433MHz active reader/writer which operates at dual-frequency for fast and reliable communications. The reader transmits at 433MHz and receives at one of 916MHz, 927MHz and 868MHz depending on what is required for the geographical region. This RFID reader/writer is designed for easy set-up, configuration and use. It is suitable for applications including access control, asset tracking and inventory control.
The active reader/writer, model 241026, is encapsulated within an impact resistant polystyrene case with UL94-HB flammability rating. It has two input contacts for door sensor inputs and two output relays for electric door strikes, magnetic locks, CCTV, lights or sirens.
The RFID reader uses parity bits and cyclic redundancy check to maintain data integrity. It receives data transmitted by a tag and sends the information in real time to a host PC. The data can be used to control access to restricted areas, track assets or manage inventory counts. In additional, it has multi-tag reading capability and supports host communication interfaces such as RS232, Ethernet or WLAN.
