... Preamble and CRC are automatically generated and added to the RF transmission. Operating within the 433MHz band the modules operate in user selectable channels. The RF650 can use any channel in 100kHz steps. The modules both use a crystal controlled design which provides narrow band performance which is far superior to other wideband ‘ ...

... Operation The Host Data Rate pins are read when the PD pin goes high. The RF650 must be put into standby mode by taking the PD pin low in order to change the selection. The size of RF data packets are set during configuration. If fewer bytes are received by the RF650 than the preset size, then after 10ms from the last byte received from the host, the RF packet will be processed (expanded to meet the preset packet size) and transmitted ...

... MHz working frequency: Config value (decimal) = [(desired RF frequency / 2) - 422.4MHz Please Note, the calculated value must be converted into hexadecimal format. The Configuration pin must be held low for at least the first byte to change the RF650 module into configuration mode. If the Configuration pin is still low at the end of the configuration then the module will send the current configuration back to the host ...

... Application Information Connection of the RF650 to an RS232 host terminal device such serial port may easily be achieved using the circuit as below. The 9 way ‘D’ socket (J1) provides the standard pinout required to connect directly to the serial port of any std PC using a 9 way male/female cable. The MAX3232 (U2, a low voltage RS232 line driver) provides level conversion between the RS232 levels on the serial port and the logic levels pins of the that direct connection of RS232 levels to the module will result in immediate destruction of the device) ...

... The RF650 evaluation board provides a reliable proven host board for development with the RF650 module. A single board is supplied, no RF650 module is included with the board and the antenna socket is not fitted. This enables the board to be used for either the 433MHz or 868MHz module with a range of antenna socket types ...
