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.

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 Regards Chris >I have a master(PC) with 10 slaves(pic16f628) that I want to connect via a >serial cable link.

By the way I think this should be under EE not PIC -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
