rs-485 and rs-422 isolated ICs

[Jeckson]

I just making isolated rs-422 and rs-485.After seach and google didn't found.

The ICs drived basically from datasheet.

Can used different IC as buffer.

The design still amateur..:-(

Thank's for advice Dennis

I think the ICs better than my ICs

But I didn't have that ICs .
Have some of ICs at pcb description.

I will used your advice ICs but after I have moneys in the future...:-(.
Thank you

here is another one isolation conccept design

2 similar design given, cheer
you'll have idea make your own iso.RS485/RS422 now, don't forget to share your design.

Hai

Thank's

I'm sticky to rs-485 network cause the prices for Ethernet ICs(i.e modules still costly).

and better when have network chips as gateway for rs-485 network...

Here's pcb for common rs-485 and rs-422
