And what happens if one of them dies.......a lot of trouble....I'd use
425...all connected in parallel so if one goes down it does not take down
the rest. At least then u could request an answer from each in turn and the
one that does'nt answer is the problem, The problem i see with your schem
below is if you ask 1 for data and say 36 is dead or locked then how do u
find which one it is,,,,if 2 goes down and you ask say 27 for data which one
do u point to as the problem

just my tuppence..

Kenny baby,
One of Two in a vast wilderness.

Thank you for all PIC members who read my email.
Now I am encouraged to design my control system as I planned.

Yes, Bill. My system will look like this.



+->Rx.PC1.Tx---->Rx.PC2.Tx--->Rx.PC3.Tx--->Rx.PC4.TX---...-->Rx.PC36.Tx--+

|                              __________                                V
+------------<----------------| Main PC  |-<-------------------<---------+
                               __________

I am trying to write a control program that will control a multivision
system, so called cubes.
So I need to adjust brightness, contrast, tint and all bunch of stuff with
PC.
Thank you.
