Hello.
Can anyone point me to an Internet source for general questions on RS485
please? I need to know several points such as; maximum line length vs.
speed, calculating termination resistor wattage etc.
Just for the record, I've been asked to develop a half-duplex 60 node
system running at 10Kbps (max.) over a cable length of up to a 100 metre
limit. Just a quick question... given the aforementioned, is twisted
pair essential? The application is in the retail environment so the
worst-case noise is likely to be from fluorescent light fittings.
Thanks for any advice.
Simon.
