Hi,
I am thinking of putting together an RS232 sniffer for the shack.
Pretty simple, just some LED's for activity.
What would be the best way ?
Can compartors be used to show activity ? I am looking for lots of them ,
hence lots of pins to watch.
We have break out boxes, but they never really seem to have all the
connections we want, for a CRO etc
Ideas ?
A circuit to switch on with a +1.2 or greater volts
Not sure what to do about the -ve swing. or even bother - activity is the
aim.
MAX232 only has 1/2 in it what I want to do
