b Selected source name displays
These show the name of the currently
selected signal (source) on the bus
corresponding to the delegation button.
c DEST (destination) button
Press this button, turning it on, to display
the names of buses allocated to the
delegation buttons in the selection source
name displays.
d Selected bus display

e Cross-point buttons
The cross-points in the auxiliary bus control
block are arranged in two rows: an upper
row (1st row) and a lower row (2nd row),
and are allocated to the buses selected with
the AUX delegation buttons. The 1st row
contains the cross-point buttons for
unshifted buses, and the 2nd row contains
the cross-point buttons for shifted buses.
When the DME 1V/K to 4V/K buses are
selected with the AUX delegation buttons,
the 1st row cross-point buttons are for the
currently showing side of DME, and the
2nd row are for the reverse side.
By holding down the [2ND] button and
making an AUX delegation selection, you
can allocate the 2nd row to a different bus
from the 1st row.
In this case, if the 32nd button is set to be a
[SHIFT] button (in a 32-button system), the
cross-point buttons switch to the shifted
allocation while the [SHIFT] button is
enabled.
f XPT HOLD (cross-point hold)
buttons
Press one of these buttons, turning it on, to
enable cross-point hold.
g KEY button
While this button is held down, you can use
the cross-point row of buttons to select key

h 2ND button
After selecting a bus with an AUX
delegation button, hold down this button,
and select another AUX delegation, thus
allocating a different bus in the 2nd row
from the 1st row.
i Source name displays
These show the names of the source signals
which can be selected by the cross-point
buttons. While the [SHIFT] button is
enabled, the shifted signal name is
displayed. If a different bus is allocated to
the 2nd row, while the [2ND] button is held
down, the 2nd row signal name is
displayed.
While the [KEY] button is held down, the
source name of the key signal assigned to
the cross-point buttons appears.
j SHIFT button
While this button is enabled, the shifted
signal names appear in the source name
display. Pressing this buttons toggles the
source name display between the shifted
signal names and unshifted signal names.
