Hi Andy , Ian + Ian
Had some success today with the 8 zone ir controller . I
decided to bypass the opto connected to incoming ir signal from Hv to
confirm my
suspicions. Tried it again and it worked but only with two ir leds inserted
in
the Zone Splitter . Looked at my schematic and realised it was slightly
different to my homebrew circuit. In my homebrew unit the driver
transistors
were connected common emitter but my new circuit was common collector
.Re
did the driver transistors and tried again. Now works with all 8 ir leds in
Zone
Splitter on all Zones . The range is approx 15ft and i monitored the
current
which was approx 5mA . I set up my Hv ports thru the
control
menu rather than a macro at this stage just to confirm my hardware was
connected
ok. Would still like to use opto isolation on the incoming ir ,will order
something from rs components. Now must update my drawing before i
forget.
