As described in the proper section, there are at least 4 I/O lines which may be associated to

The factory default is the first line for each pin. All of these lines may be preset active high or
low in the same menu.
As for the Transmitter, when "Remote Locked", the apparatus cannot be changed in its presets
from front panel knob before exciting from this condition. The input pin #6 may be associated to
