8 RS422 with Mega board ?

Grag38:
I found in old posts that you worked with that chip. Did you success on your project ?

Can you give us some schematics, or elements that will help me to realize it ?

Best Regards

I also found on the net : MultiSerial Shield - Hackstrich

May be it can be useful. Just have to remove Max232 chip and use max488. But I've to design it...

Yup, the project came out nicely. The hackstrich board is a great model, you can find Eagle files and code here:
