RE: Homevision IR(Keith)

["Keith Doxey" <lists.diyha@xxxxxxx>]

From your description it appears to me you have a dual emitter on Zone1. The LED's are in series so will have only 50% of the power of the single emitter. As you appear to have ruled out optical problems by stating thet when the zone1 emitters are unplugged it leaves 2 possibilities.

 

1. The expansion board is faulty (unlikely but possible)

2. You have a programming error and are actually sending to Zone 1 as well.

 

Get some visible LED's and wire them up instead, then you can SEE what is happening.

Set up is this:

I have 2 amps on IR Zone 1 both are sony but use different IR codes.
I have a sony amp on zone 2 which has a single emitter but uses identical IR
codes to one of the above amps.

If I send macro's to zone 1 the zone 2 has no effect at all.Thats input
selection and volume.

But If I send commands to zone 2 then zone 1 is effected. Only use inputs
for this amp.

To make things more interesting there is a 4th amp that uses the same codes
as one amp on zone 1,1 amp on zone 2 and this amp is on zone 8. When sending
to this zone all is ok and when sending to zone 1 and 2 all is ok.

I have unplugged zone 1 and sent commands to zone to and the problem
stopped. I have tried amps on different zones but end up so confused when
doing this and the problem seems to move around.

Its a messy set-up and one I must sort out but if Homevision was ever CE
approved and I was installing it and someone had like you say 5 devices the
same then are you going to get this problem??

I hope its not the board itself.

Other odd thing is some IR leads have led lamps so when I use zone 2 and
zone 1 triggers you might expect zone 1 to flash but it does not.So it must
be a weak signal leaking through.

Other point I thought about is when I brought my unit plus board I had a 9v
dc power supply.When I brought the unit for this office that came with 12vDC
would this have any effect??

Maybe this explanation will help.

Please call me if you have any ideas and a few mins to spare
