R2000 UHF Integrated RFID Reader‑Writer (ISO18000‑6C / 6B)

DS504 is a high‑performance all‑in‑one UHF RFID reader‑writer built around the R2000 chipset with fully independent intellectual property rights. Equipped with proprietary high‑efficiency signal processing algorithm, it delivers high tag reading rate and fast multi‑tag read‑write performance for ISO18000‑6C(EPC CLASS1 Gen2) & ISO18000‑6B compliant UHF passive tags.

This compact integrated reader embeds a 4 dBi circular‑polarized antenna, achieving typical reading distance of 0‑4 meters. Multiple communication options including USB, RS232, RS485, Wiegand, RJ45 TCP/IP, WIFI and POE power supply are available for flexible system integration. Supporting auto‑read mode and interactive response mode, it supports stable 24×365 continuous running. Widely deployed for attendance, access control, anti‑theft detection, logistics inventory, anti‑counterfeiting verification and industrial production‑process control projects.

Key Features & Product Advantages

1. Independent intellectual property hardware design: Self‑developed firmware & signal‑processing algorithm for stable field performance.
2. R2000 chip‑based high‑performance radio: Excellent multi‑tag anti‑collision capability, fast batch tag reading & writing.
3. Global adjustable frequency band: 902‑928MHz working frequency; supports FHSS frequency‑hopping or fixed‑frequency transmission, configurable to satisfy regional radio regulations worldwide.
4. Tunable RF transmit power: Output power max 30 dBm with 0‑30 dBm adjustable range to match different reading‑distance requirements.
5. Built‑in 4 dBi circular‑polarized antenna: Typical read range 0‑4 meters (actual distance depends on tag model and site environment).
6. Dual working modes: Automatic continuous reading mode and interactive response trigger mode for diversified business workflows.
7. Rich multi‑functional interfaces: USB, RS232, RS485, Wiegand standard interfaces; optional TCP/IP Ethernet, WIFI and POE power supply, easy docking with access controllers, PLC and host software.
8. Low‑power optimized circuit: Single +9 V DC power input, low power consumption for long‑time continuous operation.
9. 24/7 reliable continuous operation: Designed for non‑stop 24‑hour × 365‑day running for industrial and commercial identification applications.
10. Compact all‑in‑one structure: Reader and antenna integrated in single unit, saving installation space and reducing deployment complexity.
