Can someone please explain the purpose
of R4 on this RS232 interface example from
Microch*p. Its not for current limiting during shorts is it. I'll need a fat high wattage res for that won't I?
Its from the "caring and feeding of
the 1674 pdf" - its not explained there.
Also what effect does higher value caps
have - I want to be able to use 1uf or 10uf caps.
Thanks.
