You
can use Homevision WITHOUT needing the expansion board
The IR
signal is positive from the tip of the 3.5mm jack.
Use 2
of Port A's pins to ground the negative side of the IR
LED's
Eg.
Set Port A1 (digibox1) LOW
Send IR
Set Port A1 High
Set Port A2 (digibox2) LOW
Send IR
Set Port A2 high
by
setting both Low you can send commands to both.
Give
it a try.
You
will need VERY low power MiniEmitters (put a resistor in series) so the IR
doesnt spread to the other box, trial and error by increasing the resistor
value.

Last week I ordered 2 Sky+ boxes, and they're due to be installed
soon. Since we don't have any terrestrial TV we need to be able to
watch
at least two separate channels, and with the Sky+ inbuilt Tivo player two
favourites can both be recorded even when the schedules clash.
Great!
Anyway, I got thinking about controlling the 2 boxes as they will be
next
to each other in an AV rack. I assumed that since the Sky+ system is
designed to use 2 boxes then there would be a set-up screen, switch etc..
to
have one box set to 'Sky box No.1' and the other to 'Sky box No.2' and the
same IR remote to control the two separately/discreetly. I've just
got
off the phone with Sky+ technical and they say that there isn't a way to
control them as there aren't any discreet codes - so both boxes will
respond
to the IR remote at the same time :o( Technical said that the number
of
people that would want 2 boxes next to each other is very low so they
didn't
bother with adding this feature!
They said that I could use a standard digibox for the second box as it
has different IR codes than to the Sky+ box.
I suppose I could use HomeVision's expansion card multi-zone IR to
control 2 Sky+ boxes, but things start getting complex(ish)
Just thought I'd let you all know before someone else orders 2 Sky+
boxes.
Any other suggestions?
