A few pics of my Rx Splitter Combo proto type
Top two pics showing front and rear .
Bottom left showing the rx receiving an ir signal
Bottom right showing rear, with stick on emitters plugged In
I will use these as I should only require approx 4 points per zone max as my equipment will be mostly located in each zone . The stick on emitter holders are Clipsal plastic end caps (25mm + 20mm) with 3mm ir leds inserted.
