I think that would work just fine.  Just run +12 (or +5 or whatever) through
a current limiting resistor in series with the relay coil and connect the
other end of the coil to a TX OUT line.  That will energize the relay when
the Orion goes into transmit and pulls the TX OUT line low.  And a N.O.
contact can switch the voltage you want to control.
