RE: Interfacing PIR's

["Henderson, Darren" <Darren.Henderson@xxxxxxx>]

Ok diagram came through well, but what do I use in the HA PC to pick up
these outputs ?

Patrick has mentioned an ISA card he has that can accept the outputs as you
described, and Dan mentioned a serial device (what is this device Dan ?,
any
more info ?) that can do something similar. Now I realise that some
programming will have to be done, but once I have a method to interface the
outputs to a PC, then I can write something to inform Homeseer.


Sorry about sounding like a newbie, but I am :o)
