BizTalk RFID with XR450, Light Stack and Motion Detector - Help!

[Christian Loris]

I have an XR450 with a DC400 LIB. I've wired everything up in stand-alone
mode and it works great:

1. Green Light Comes on when running
2. Orange flashes with tag reads
3. Motion sensor controls polling

When I turn on BizTalk, this all stops. The Orange light goes solid and I
lose the green indicator.

We wanted to modify the behaviour of some of the lights so I started out
attempting to do this (using the techniques described in
http://social.msdn.microsoft.com/Forums/en-US/biztalkrfid/thread/1ea3cf93-cc5f-497b-86bb-9b5ea06c4f73):

1. On BT RFID process start, the green light goes on.
2. On motion detect (Input1), do not ignore any reads - pass them through
3. On tag read - flash orange off then on

I've validated my control of the lights with some initial process startup
sequences. However, once tags start flowing, it's like I am fighting with
the XR450 for control of thelught - the Orange one in particular. So I told
the XR450 to ignore the LIB and now I get control of the lights without
interferance. However, I do not see the motion detects anymore. This is
where I am stumped. How can I get my event handler visibility into the
motion detector while trying to get the XR450 out of the loop from control of
the lamps?

Any suggestions and such would be appreciated.
