Hi all,
I´m trying to make an portable DMX analiser that you would select a channel and it would display the actual value of that chan. All is working right, I got 4 buttons, a 2,5 digit LCD and I´m using the 75176 for the RS-485 conversion.
But when im connect it to a lighting controller and try to read out the chan values I get weird numbers and channel interference (one chan up changes the value of the last one... eg. changes on chan 2 do weird number on chan 1...)
If you would like to help me (PLEASE!) the source can be found here.

Thanks, Gabriel.
