First convert your paralel data into serial one, of course you can do it in harware or software. Then use MT8880 (DTMF Tx/Rx) controlled by MCS51.
MT8880 is included ring indicator but I never use it yet. I succeed receiving and transmitting data via power line 220v using this chip. Even sending a music about 50 meters. I hope this usefull. |
