Consider the question retracted. For all my long hours of testing, the switch cable lay passively plugged into the wrong digital in.

This is a confirmation of one of Murphy's many computer laws:

"In every case in which computer error is asserted, there are at least two human errors, including the error of blaming it on the computer."

Thanks anyway.
