RE: [ECS] micro-redac and relays

David,

First, thanks so much for all your help.  Second I am apparently still doing
something wrong.

My Redac has the 8 relays and the 8 analogs across the top of the unit.
These are so labeled.  The screw posts along the bottom are not labeled and
I assume these are the digital inputs.  I ran wire to the basement (where my
system is) from the transformer.  I am using some phone cable I had laying
around if that matters.  I hook 1 end up to the screw post labeled "1" and
the other to either "9" or "10" (the two grounds).  I set up an item in item
editor.

When I first create an item in a group window it shows the item (let's call
it "digital") as being "high."  I would think this is correct (the initial
state is set to 'none').  When I apply power by turning the receiver ON the
item (in the group window) begins to toggle back and forth between  "low"
and "high."  Reversing the wires on the Redac doesn't help.  In fact with NO
connections to the Redac the item still toggles back and forth. I assume
that I am missing something silly? (the good news is that the Powerflash is
MUCH more reliable in it's new location).

Simply connect the positive of your power (transformer) supply that is
plugged into your receiver to a numbered input 0-7 on the Redac and the
negative to the G connection which stands for Ground. There are 2 grounds
and the 8 connections that correspond to the digital inputs.

After you have it all tested add the fuse and current limiting resistor.
