RFID Keychain

RFID Reader according to 1-Wire Bus, RFID - iButton reader iButton, security and authentication system on 1-Wire basis Contactless reader unit for reading RFID* cards or keys via the 1-Wire bus. RFID cards are read like normal iButton keys via 1-Wire bus. Each RFID card or key has a unique and uniquely assignable serial number. The only difference is that the RFID's are interrogated wirelessly. The RFID reader is intended for permanent installation in machines, doors or devices. Ideally suited as an access system for front doors or secure areas in companies and public authorities. The data transfer between RFID card or key and the 1-Wire bus is serial. Only three wires with a power supply, data and ground line are required. Examples of use Security and authentication system Goods tracking within logistics Access rights for devices and machines Inventory Type DG9092L2 RFID tags RFID UNIQUE 125kHz, 64 bit Reading distance 2 - 10cm, depending on the quality of the cards or buttons to be read Power supply 6.5 to 32VDC Power consumption approx. 12mA without LEDs Connection 5 wires, approx. 40cm with open cable ends Cable Assignment Yellow: Power supply 6.5 - 32VDC Grey: Ground, GND White: 1-Wire Data Green: Cathode (minus) for green LED Brown: Cathode (minus) for red LED Design Plastic housing, M12 thread LED indicator LED green and red (no series resistor necessary) LED Power consumption approx. 10mA per colour Bus interface iButton, 1-Wire bus with 5VDC voltage Software Like all 1-Wire and iButton components, each RFID tag has a unique and unambiguous serial number. Compared to standard iButton, the data transfer is contactless. As with all 1-Wire modules, several reader units can be operated on one 1-Wire bus. The RFID reader has the following 1-Wire commands: - Read Rome, 33h - Search Rom, F0h The number of the RFID tags is transmitted as follows: CRC (1 byte), 0x00, serial number with 5 bytes, Family Code 01h (DS1990) Dimensions 28 x 9 mm (DxT, visible range) 15mm installation depth, M12 plastic thread Assembly Fixing by M12 threaded screw connection Scope of delivery reading unit with approx. 20cm connection cable, tension spring for mechanical fixation Hint: No series resistors are required for the LEDs. To switch on an LED, only the corresponding cable must be connected to GND. *Reading of UNIQUE 125 kHz RFID tags (Manchester coding) via the 1-Wire protocol

Door opener / Access system via iButton / RFID - Functional extension for 1-Wire Controller / 1-Wire Gateway Features: Independent access system for electric doors / door opener via iButton and RFID key (RFID via RFID to 1-Wire reader, Art. No. 11614) the 1-Wire Controller / 1-Wire Gateway takes over the control of an electric door opener when an RFID or iButton key is contacted or brought into the area of the RFID reader. Additionally, an additional feedback output for an LED display can be controlled. Internal relays of the 1-Wire Controller 2 or any 1-Wire module in the 1-Wire network can be used as control output Door open time can be set in a wide range (1 - 65000 seconds) Additional display output for feedback via LED displays Electrical devices can also be activated for a time up to 65000 seconds incl. iButton / RFID Fast Mode function extension NO superordinate software / control system is required for the door opener function max. 30 keys can be used. If further 1-Wire devices are controlled, correspondingly fewer keys Application: With this function extension for 1-Wire controller / 1-Wire gateway, a door opener function or access system can be implemented via iButton Release of electrical devices for a certain time, e.g. for TV, beamer or game consoles (child safety lock)
