GENERAL DESCRIPTION
HF reader Module RR9091TM is designed upon fully self-intellectual property. Based on proprietary efficient anti-collision algorithm, the series features excellent tag read/write operation performance with high identification rate. The series can be widely applied in many RFID application systems such as Logistics, Personnel Identification, Conference Attendance, Access Control, Anti-counterfeit, Jewelry Management, Self-service of Laundry and Industrial Process Control.
FEATURES
l Self-intellectual property;
l Support ISO/IEC15693, ISO18000-3 protocol tags;
l RF output power over 1W;
l Advanced anti-collision algorithm, high identification rate, typical tag process speed is over 80 tags/s;
l Support standard 50ohm RFID antenna with effective distance up to 70cm*;
l Antenna open/short circuit tolerant;
l Support Scan-mode;
l Support Transparent Command operation;
l Support addressable multiple antenna ports;
l Support DPPM/WPPM tag-parsing mode;
l Support reader network;
l Low power dissipation design;
l Provide DLL and Demonstration Software Source code to facilitate further development.
Scan-mode: It refers to reader’s automatic working mode.
Transparent Command Operation: It is an advanced feature designed to support tag’s future functions and different chip vendors’ customized tag functions.
DPPM/WPPM Tag-parsing Mode: DPPM tag-parsing mode means depth-first parsing pattern and WPPM means breadth-first parsing pattern. They are different methods of decoding multiple tags.
