Fw: Improving Xantech IR ?

[Gareth Cook <g@xxxxxxxxxx>]

It's sluggish - but at no particular time really.

The cbus switch merely causes the IR receiver to flash - thats more
annoying than anything else. Dont think it affects it any more tho. Mebe
my cbus comment was a red herring - the sluggishness was there before cbus
was put in.

Hi Gareth
Is the interference only there for a short time ?? ie
while
the cbus switch is txing its message on the cbus network ?? or is it
happening when theres traffic on the cbus network  in general ??
