Dear piclist members,

I have a master(PC) with 10 slaves(pic16f628) that I want to connect via a serial cable link. The max distance can be up to 200 meters from the master unit
Does anybody know where can I find a information or links about hardware/electrical diagrams to build a data link cable driver between these devises.

Regards

Francois

Sure!  But you forgot to mention which protocol (Hardware) you wish to use.
(RS-232, RS-422, RS-485,  what?)

I believe what you are looking for is RS485

have a look here
http://dbserv.maxim-ic.com/appnotes.cfm?appnote_number=373

but you should find plenty of info from elsewhere as well

Chris

By the way I think this should be under EE not PIC
