The problem is *NOT* a layout problem but the result of a deliberate, but
somewhat questionable design decision by Lear Siegler.  It is their method
of starting a terminal self-test routine!!  To the best of my knowledge it
applies to several other ADMs as well, including 5 and 9.  Disconnecting
the offending lead indeed fixes the problem (Learnt during more than one
$75.00+ service calls by LSI people at the large installation I used to
work for).

Three cheers for standardization and un-documented "features".
