___Wireless Data RF Modules 

   The DTD465 is a serial of high-performance embedded wireless data transceivers. Operating in the 429~434 MHz ISM band, this module is capable of providing reliable wireless data transfer between almost any type of equipment which uses an asynchronous serial interface. The small-size and superior RF performance of this module make it ideal for many applications.

 Features:
 Key features of the DTD465 include:
  • Low power transmission with 10mW, 500mW, and 1W available.
  • With 433MHz as factory default carrier frequency, but 402~470MHz available if needed. Transmission within a public, license-exempt band  of the radio spectrum – this means that it can be used without access fees.
  • Providing security, reliability and high tolerance to interference
  • Based on the Gaussian Frequency Shift Keying (GFSK) modulation, the high-efficiency forward error correction channel encoding technology is used to enhance data’s resistance to both transient interference and random interference and the actual bit error rate of 10-5 ~ 10-6 can be achieved when channel bit error rate is 10-2.
  • Long Transmission Distance
  •   Within the visible range, when the height of antenna is higher than 2m and The Bit Error Rate (BER) is 10-3, the reliable transmission distances respectively is 4500m @1200bps, and >2000m@9600bps.
  • Transparent data transmission
  •   Transparent data interface used in transceivers is for meeting many standard or nonstandard user protocols. Any false data generated in air can be filtrated automatically (What has been received is exactly what has been transmitted).
  • Multi-channels
  •   DTD465 transceivers offer 8 channels, if needed, 16 or 32 channels available to satisfy various configuration of communication under user’s demand at the same time
  • Two data port interfaces with three driver levels
  •    DTD465 transceivers provide 2 ports with three driver levels: a UART interface of TTL level, a RS-232 driver level and a RS-485 driver level, which both are defined by user software (define it just by plugging out and in one short circuit device and then power on). A serial I/O data port with handshaking and hardware flow control, allow the DTD465 to interface directly to any equipment with an asynchronous serial interface.
  • Big data buffer area
  •    With optional interface baud rate: 1200/4800/9600/19200/38400bps and 8N1/8E1 data format (set by user), the transceiver can transmit unlimited data frames with flexible user program.
  • Intelligent data control and no any extra programs required
  •    Even for half duplex communication, no any excessive programs required. All RF system data transmission/reception and other On-the-Fly conversion and control are performed by DTD465 transceivers automatically.
  • Lower power consumption & Sleep function
  • With +5V power, the receive current is less then 50mA, the transmit current is <400mA, and the sleep current <5uA.
  • High reliability, small and light
  •   By using monolithic radio-frequency integrated circuit and single-chip MCU, the transceivers have less peripheral circuits, high reliability, and low failure rate.
  • More options of configurable antennas for user different applications
  •  
     Applications:
        While the typical application for the DTD465 is to provide a short- to mid-range wireless communications link between DTEs, it can be adapted to almost any situation where an asynchronous serial interface is used and data intercommunication is required. 
    Typical uses for this module include: 
  • Auto Meter Reading system.
  • Remote control and monitoring.
  • Remote Camera/Robot Control.
  • Traffic Control.
  • Fleet Management.
  • Automatic data collection.
  • Data communication used for railway, oil field, dock and army.
  • Medical and electric equipments control.
  • Light and home appliances intelligent control.
  • Security alarm and monitoring control.
  • Check attendance system and positioning in coal mine.
  • Car burglar proof, pressure detecting of the wheel, four-wheel orientation.
  • Wireless POS in shops.
  • GPS system.
  • LED display in thruway and public places.
  • Queue-management system in bank and government.
  • Smart wireless PDA terminal for restaurant ordering system and voting system.
  • Telemetry system.
