Something I was going to mention before but got tied up in a whole new
mess. <br><br>
Russound makes an IR Hub/Repeater, this is what I'm going to use as an IR
blaster for now. I talked to their tech support wednesday, I asked if I
could drive their repeater from a serial port. Their reply was, "The
block is expecting a standard IR signal (Tip & Ring i.e.'signal &
ground') It was meant to handle connections from the IR-out from many
different manufacturers. So as long as the serial port is sending an IR
signal, it will work" I told them that I could control devices
from the serial port using a resister, diode and an IR-LED. they said
"then it should work"<br><br>
The 857 connecting block from russound goes for around $35US. You
can use a 9-12V transformer to power it, or if the output from the device
is high enough ( again 9-12v) the 857 will power itself from
that.<br><br>
The advantage that I see in this is that the 857 has 6 mini jack IR-outs
that are intended for the little stick-on IR eyes. Which means you can
have up to 12 devices connected to the block and have a nice clean
look.<br><br>
What I'm planning on doing is, from my serial port, making the simple IR
transmitter, instead of an IRLED, I'm going to make a fairly long lead
with a 2-pole mini-jack. plug that into my 857 block, and use a couple IR
stick on eyes on the devices I'm going to control.<br><br>
<br>
Anyway, the reason I mentioned this is that, if the "PVR
Multi-Circuit" had an IR-out Jack, a device like the 857 can be
used. Just tie the jack in as if it were an LED.<br><br>

as long as you've got the power and the parts are cheap, I'd say the more
the merrier. For Tx at least, you just need to spray IR out (I
suppose if different devices have different delays it could cause
interference, though). I'd say all three.... put a header inside, a
common plug on the front panel (e.g. 1/8" minijack), and a Tx LED on
the front panel facing forward. It'd be easy to put jumpers on the board
to configure which ones to turn on. If they don't interfere when you have
them all on, you could probably even forgo the jumpers (although the more
cheap tweaks, the better). I'm sure that some people have
configurations where different boxes are in different places and could
benefit from diversity transmitters.<br><br>

you who have provided input to this project. It's really helping me
design something that will meet the end user's wishes and needs.
Now, some more questions: How should IR emitters (blasters) attach to
this board? I can have headers on the pcb that would require
routing the wires out the back of the PC keeping them hidden or put
sockets on the front panel where the wires would be visible and easily
accessable...or maybe both? Should I mount one very powerful
emitter on the front panel also? It may be strong enough in some
cases to control everything without the need to run emitters on
wires.<br><br>
