Are terminating resistors necessary on my RS-485 network?

Article Number: 31 | Rating: 4/5 from 3 votes | Last Updated: Fri, Jan 18, 2008 at 12:00 AM

No, generally terminating resistors are not required, and can actually cause communication problems on the network. Every network is different, and has different requirements, but it is best to start without terminating resistors, and add then only if necessary.If terminating resistors are necessary, then 120 ohm resistors should be used.
