[Hai-users] Update: Sharing a TW-523 with ADICON RLY8XA

[Byron Peebles]

You can check the ADICON (www.appdig.com) site for the postings,
but I was able to confirm that the ADICON 2500 RLY8XA relay units
do NOT have an X-10 transmit (TX), so putting two RLY8XA units on
one TW-523 X-10 interface with a four-wire telephone line splitter will
work and will not damage the interface within the RLY8XA units.

Of course, the lack of a TX will prevent them from reporting their status
via X-10, so you need to maintain it yourself or trust it at the 
controller unit status.

For me, I'm going to put the more important relays into spare Zones 
(there aren't
many in the Omni IIe.)  Because the RLY8XA has a Normally Open and a 
Normally
Closed connector on each relay, using the NC with a zone will give an 
ACTUAL indication
that the relay has closed the NO side. (I guess you all know this, but 
it was an Aha! to me.)

If it had occurred to me six years ago, I wold be using NC sides of 
relays for this everywhere.
I've been programming flag and toggles for ages.  This eliminates all of 
that.
