Data Transferrinf Over a 25 Meter Wire.


Recommended Posts

Hi
I am designing a new Language laboratory System.
I want to send serial data via a Common bus to all Stations (Students devices).
The length of this bus is around 20-25 meters. Which method is the best
for transferring Data. I mean FSK, RJ485 (if I wrote it right), SPI (that I don't think it work) or ...
The Baude Rate is Around 9600 bps

ThanX in advance

Thank you very much for your reply.

Master Should send Data to all slaves and Retrieve some data from each Slave.
Just like a I2C Bus System.
But the difference with this system and a Small I2C Bus System is Distance between Master and Slaves.

BTW, Each Slave is a MCU Based Circuit.

ThanX
Shahriar
