In my case, I did connect as shown on the datasheets, but the TSOP did no=

*sustain* the output low as long as the transmitter was sending a continu=

38khz carrier.  So far I had not been using a microcontroller, but just=20
sending the output to an oscilloscope.  I interpreted the datasheet secti=

on suitable data format as *IF* I intend to use some coding scheme, but=20
apparently it is a requirement.

At this point, I've re-architected the IR section such that I will have a=
 new=20
sub-app that will interpret the IR signals and farm it out to the 6=20
individual units as they require.  One of the transmitter buttons will=20
function to select which device I need to control, and the other will=20
set/control that device.  I will now only need only one IR receiver/decod=
er=20
but I'll add a single 7-seg digit to show which unit is being controlled.=
 =20
I've come up with a very simple coding scheme to discern one of 3 differe=
nt=20
signals from the transmitter.  Wish me luck... :-)
