Andy,
Have you had a look at some of the
products offered by Niles Audio.
They seem to have a number of IR distribution
products.
http://www.nilesaudio.com/misc_products/infrared.html
I think one of the main
advantages/features of this type of system is that the sensors give you an
LED
on/off status of the product you are controlling in addition to the usual
'blink'

Subject: [ukha_d] HV IR
Distribution Was Gurus brain required...
I've been having a serious think about this
one
and came up with the
following,
The solution should be a '2 box' one. One box
would be the Homevision
IR Zoner the other would be the 'single to
multiple emitter' box.
Why? Ok, well the Homevision box speaks for
itself. The question is
would you want to build the 'single to
multiple
emitter' that only
ever worked with Homevision? The answer has to
be
no. The single-to-
multiple-emitter box could be made to perform
the
same functions for
a number of IR sources. The HV IR zoner is
effectively one source,
but what if you wanted to use the
single-to-multiple-emitter box with
comfort..a new design?
So here is the idea.
HV Zoner box
1 x 3.5mm mono Jack for IR in (from
Homevision)
8 x 3.5mm mono Jack for IR out - to either
emitters or to the single-
to-multiple-emitter box
design as per http://groups.yahoo.com/group/ukha_d/files/HVIR.jpg
IR Distribution (single-to-multiple-emitter
box)
8 x 3.5mm mono jacks from IR input box (eg HV
Zoner)
64 x 3.5mm mono jacks for IR emitters - split
into
8 zones of 8
outputs (i.e. each one of the 8 inputs
emmits on 8 of the outputs.
If homevision was outputting on all 8 zones
could
it cope?
The IR distribution box mut be able to cope
with
ALL 64 emitters
firing but should not affect the input box (eg
HV
Zoner) - Seperate
PSU? (as per Ians message?)
Perhaps this could be integrated with Ian's or
Nigel's IR circuits
too to give Zone control from a remote
location...
I thought if this were a more generic design
then
it would appeal to
more people...
Anyone got any thoughts/ideas?
