10 / 12 page DS0353-9 March ‘05 ©2005 Reg. No. 227 4001, ENGLAND Page 10 TRXQ1 RXQ1 FM NARROW BAND TRANSCEIVERS TRXQ1 application schematic: logic level connection to host micro controller. Direct connection of the TRXQ1 to a host micro controller allows the design of complex systems where the host micro controller provides all of the processing power and the TRXQ1 acts as the data carried between system nodes. The use of the broadcast mode will allow multiple transceiver systems to be implemented and with suitable software and a user defined protocol is will be possible to implement complex networks where control of the data path, retries etc. are under the control of the designer. Where a point to point system is required then the addressed mode will provide this and also give the required level of security. This, along with the automatic retry feature of the TRXQ1 module will remove from the system designer all of the normal overhead of writing communications software. As was the case with the RS232 example given above, the TRXQ1 hybrid requires 4 signal connections to operate correctly. TxHOST: serial data which is to be transmitted by the hybrid. RxHOST: serial data which has been received by the hybrid. \CTS: control output to the host is low when it is Clear To Send data to the hybrid. \RTS: control input from the host is low when it is making a Request To Send data from the hybrid. In some addressed mode applications the learn/erase components may not be required and the LRN/LED pin could be connected to the host micro controller which would be programmed to handle the functions of this pin. Where the module is to be used in the broadcast mode then the learn/erase components will not be required which will lead to further simplification of the circuit. |
