Bluetooth Management System Advantages Parking: 1, Bluetooth products are optical excitation, wake-up, high-tech crystal Bluetooth communication, fast reader, reading distance away, has a good direction, the reading distance can be controlled (1-5 meters 5-10 m, 10-20 m adjustable) 10-60 km per hour may not stop the reader. 2, up and down ramps, corner entrances not stop the reader, to avoid the vehicle stalled, Banpo start. 3, protective film from the vehicle (such as riot film) effect for all vehicles. 4, do not stop, do not open the window reader; bad weather snow storm is no longer the owner of the impact of the car window. Do not stop the reader, greatly improving traffic throughput, rush hour traffic jams are no longer long queues phenomenon. 5, no mutual interference between the reader (Bluetooth communication using advanced technology and code division multiple access), good direction, an effective solution to mutual interference problems all around the driveway. 6, the frequency of 433MHZ, the frequency has not radiation damage. 7, card good stability, product jamming, anti-fading, interference from other communication products (such as: mobile phones and other wireless communication products). Phone calls will not burn cards. 8, Wiegand 26/34, RS232C / 485 adapted to interface with good scalability can be common in other car park, highway, long-range identification fields. / ID card is fully compatible with existing equipment to the IC. Operating mode: light excitation positioning, DES encrypted communication, Hugh eye wake. . Power supply: DC12V --- DC20V Working current: 1A Bluetooth power: 12W Operating Frequency: 433M excitation frequency: 38K reader angle: 85 degrees reading distance: 1 ~ 35 m adjustable tag protocols: 3DES encryption protocol interface types: Wei Root 26/34, RS232, RS485 Storage temperature: -45 ℃ ~ + 95 ℃ Operating temperature: -30 ℃ ~ + 75 ℃ Relative humidity: 95% maximum size: 25.2 * 32.2 * 6CM Ma Feida Bluetooth card factory Contact People: Zhengsheng Tel: 18122701519 020-28948999 Enterprise QQ: 2355515420 Website: http: //www.gdmdf.com group Electronic Technology Co., Ltd. in Guangzhou
