CHAFON CF591 UHF RFID Access Reader, 9 dBi Antenna, 865~868MHz, RS232 & WG-26, Adjustable 0~26 dBm, IP65

The CF591 requires a stable 12V DC power supply capable of delivering 2A current. It is connected via the dedicated power port. Using an underpowered or unstable supply may result in reduced read performance or module malfunction.

The module provides two primary interfaces for access control integration. Use the RS232 serial port for direct communication with a PC or controller software. Alternatively, use the Wiegand-26 output (DATA0 and DATA1 lines) to connect directly to the Wiegand input of most standard access control panels.

Yes, the reading range can be influenced by adjusting the RF output power from 0 to 26 dBm via software commands sent through the RS232 interface. Reducing the power decreases the interrogation zone, which can help prevent unwanted reads from distant tags and comply with local RF emission regulations.

Yes, the CF591 features an IP65-rated enclosure, making it protected against dust ingress and low-pressure water jets from any direction. This rating makes it suitable for outdoor installation in weather-protected areas, such as under eaves or in entryway shelters.

The CF591 is designed to read passive UHF RFID tags compliant with the EPCglobal Gen2 (ISO 18000-6C) standard operating in the 865-868MHz frequency band. Ensure your tags are tuned for the same frequency region (ETSI) for optimal performance.
