900Mhz COFDM Wireless Transmitter


1 Watt COFDM Wireless Transmitter

900Mhz High Speed Radio Data Modem 1 Watt RS-232 / RS485 Data Radio




The XTend RF Module was engineered to provide customers with an easy-to-use RF solution that provides reliable delivery of critical data between remote devices. The module transfers a standard asynchronous serial data stream, operates within the ISM 900 MHz frequency band and sustains up to 115.2 Kbps data throughput.


Key Features:


Advance Networking & Security


True Peer-to-Peer (no Master device required),Point-to-Point, Point-to-Multipoint & Multidrop

FHSS (Frequency hopping spread spectrum).10hopping channels,each with over 65,000 unique network addresses available


AES Encryption:


performed using a FIPS197 certified implementation on a Phillips LPC microcontroller

128-bit AES for international variant.


Low power consumption:


2.8 - 5.5 V Supply Voltage.

Pin,serial port and Cyclic

Software sleep modes supported

Shutdown pin enables hardware sleep mode,that draws only 5 µA(typical)



  • No configuration necessary for out-of box RF communications
  • Free X-CTU software (Testing and configuration software)
  • RF modules easily configured using,standard AT & binary commands
  • Transparent Operation (wireless links replace serial wires)
  • API Operation (Frame-based communications)
  • Portable
  • (small form-factor easily designed into a wide range of data systems)
  • Software - selectable I/O interfacing rates
  • Multiple data formats supported (parity,stard and stop bits,etc.)

1* Module

1* RS-232data cable

1* power line

1* small antenna


Optional accessories:


RS-232 programming cable. (For user get through the computer's RS232 interface module parameter settings)

USB interface programming join line. (for user get through the computer's USB interface module parameter settings)

the data transmission test equipment. (User-friendly in the selection or the actual use of the module testing)

optional antenna. (The user can follow according to their actual situation to choose their own antenna,so that achieve the best results)




1, in order to achieve the best communication results, try to use a smaller power supply ripple factor, the maximum current power supply module should be greater than 1.5 times of the maximum current.

2, TTL, RS-485, RS-232 three interfaces can only choose one.

3, the transfer rates are divided into: the number of interfaces rate: users can be changed by KYLPRO.exe PC software;
