Fsk Transceiver Modules for Home Security Alarm and Remote Keyless Entry

RY4432 wireless transceiver module

RY4463 adopts Silicon Lab Si4463 RF chip, which is a highly integrated wireless ISM band transceiver chip. Extremely high receive sensitivity (-126 dBm) and +20 dBm output power ensure that the covering of the range and improve the data link performance. Built-in antenna diversity and the hopping function can be used to aggressively improve the performance.

Users can set the button transceiver frequency, transmitter power, wireless transmission module, serial number rate of transmission rate, the serial data bits, stop bits, parity bit parameters.

Work mode:
1) Transmitting mode: Send data packets period ( In setup mode, not to send data packets );
2) Reception mode: Enter the receiving mode after power up. Receive data packets and send to the serial ports.
3) Regular transmitting mode: the modules continuously transmit;
4) Regular receive mode: module is often receive state (not forwarding data);
5) Sleep mode: data transmission module in the standby state.
Button operation
1)  SET Button
Press enter setup mode, such as the setting of the last one parameter, then press jump set
mode.
2)  UP /Down Button
In setup mode, changes corresponding to the set parameters by these bottoms
3)  Read Button
Read parameters of module, and updated on the LCD display.
4)  Write Button
The button will be the current display interface parameters of write current connection
module.
5)  Default Button
Button factory default configuration parameters written to the current connection module.
Note: The data transmission module with FLASH, power-down all the parameters set can be saved automatically read the relevant parameters of the plug inside the module after power-on.
