hi every one
i m trying to design a digital clock. One Master-Clock that will send a serial data at 9600 baud-rate, and slave clocks will receive the data and will display it, for Master-Clock, I used AT89C51 and for Slave-Clock AT89C2051.
The most near Slave-Clock is approximately 12-15 feet, but the last one is approximately 300 feet far. my idea is to use coaxial-cable, (for common ground and signal)
------------------
Questions?
1) Will i need any buffer/booster to send data at the last end and receive it perfectly?
1-i) If Yes, so how can i boost it?
2) Is Coaxial Cable is good for this purpose
Thanks
