Re: HV to CBUS

[Kevin Hawkins <lists@xxxxxxxxxxxxxxxxx>]

At the moment the ports are spare and may (or may not ) be used later.
They were for use in the xAP board for future attached peripherals like
perhaps a Meteor CID  - HomeVision - TOM10 temp board, Matrix switcher
etc etc.  There is also the electronics for an X10 interface,  keypad
and lcd screen on there - basically it was a good flexible base for
later expansion.   I can't implement the PCI functionality , or the CNI
as there is no information available to do this, and it is probably very
complex, or resource intensive anyway.
