DS814 split high-performance 4-channel UHF UHF electronic label reader is suitable for multi-label reading and writing, completely independent intellectual property design, combined with proprietary efficient signal processing algorithm, while maintaining high literacy rate, to achieve fast reading and writing processing of electronic labels. Can be widely used in logistics, access control systems, anti-counterfeiting systems and production process control and other radio frequency identification (RFID) systems.
Features:
Completely independent intellectual property design;
Operating frequency 840 ~ 960MHz (can be adjusted according to different countries or regions);
Based on the Impinj R2000 read and write engine design, electronic labels that comply with EPC CLASS1 G2 and ISO18000-6B
standards are fully supported.
Operates in broad spectrum frequency hopping (FHSS) or fixed frequency transmission mode, supports RSSI function, and the
peak label inspection speed is greater than 700 photos/second;
Output power up to 30dBm (adjustable);
Built-in 4 external TNC antenna interfaces to support antenna detection;
Support response mode and real-time inspection mode;
Label cache capacity: 1000 @96bitsEPC;
