This connection is typically made in two stages. A short cable, internal to the
instrument, runs from P6 of the computer board to a IS-pin "D" connector. The
signals are then brought to the remote annunciator via an extension cable which is
of a length appropriate to the specific installation sit. This cable extends pins
1,2,S,6,9,10,11,13 and 14 of the "D" connector from the instrument to the
annunciator.
