Library's collection Library's IT development CancelSerial communication is commonly used in PC interface, but serial
communication that commonly used is RS-232 which only can communicate in
one to one.
In this final project design a RS-232 to RS-485 converter which in the RS-485
system can communicate in one to many using a multidrop network system.
An Application in order to use this converter is monitoring a computer, so that ini
one computer we can see what they doing in the order computer by looking in that
monitor.
Software designed under Windows (32 bit) using Delphi 3.0 from Borland
International, Inc Software. There is two kind software which one is a master that
use to control which computer we want to see while the other one is slave that use
to send the picture in the other computer which stay resident and active.
For hardware it made 3 RS 232 to RS 485 converter that installed at the 3
PC which one used for master and 2 PC for slave.
Testing in the hardware is by iooking at the signal input from the PC and input-output
signal from the IC that used in the converter, testing in the software is the
truth of sending data, picture compression, and the speed of transmission. From
the data gained shows that the errer is 1% in transmission data and the speed of
transmission.
