2.5 Legend Text Selection using ProCS™
The JA31-N01 has no required adjustments, but the configuration program ProCS™can be used to customize the
text for each legend either at the time of ordering the unit, or if text changes are required after installation. The JA31-
N01 need not be connected to a computer to select the legend text.
For information on ordering customized legends, refer to the ProCS™ Ordering Instructions on the JAC website.
2.5.1 Front Panel Switches
The Front Panel Switches window is used to specify the text for each legend.
Note: If the name of a front panel switch is changed using this software, the change will be incorporated in
the connector maps and interconnect, to give truly customized installation diagrams.
In the example shown here, the option ‘New…’ has been selected. A
pop-up ‘New Label’ window will appear, allowing the user to create a
customized legend –in this case, JAC. The new legend name will
now be shown in the appropriate position on the faceplate
representation in the software program, and will be used in the
connector maps and interconnect.
2.5.2 Connector Maps
This section contains connector maps and interconnects that are automatically generated to show changes to switch
labels that affect the installation of the JA31-N01.
Among the options is ‘- - - -‘ which signifies that
the legend will be left blank, and ‘New…’ which
allows the user to enter a completely new
legend of up to five characters. If a ‘new’
legend has been added, the option ‘Edit …’ is
added to the menu to enable changes to the
newly created label.
Clicking on a customizable legend will open a drop-
down menu listing the options for that label. The
currently selected option will be highlighted. To escape
from the menu, click on the desired option, or right-click
in the window. A 'Print…’ box will appear. Click outside
the box to escape, or select it to print the 'Front Panel
Switches’ window showing the current label selections.

3.3 Operation
Note: The JA31-N01 does not require power from the aircraft for operation.
3.3.1 Panel Lighting
The legends will be illuminated and dim through the aircraft lighting bus.
3.3.2 BUS Selection (Talk Groups)
When the USER switch is in the BUS 1 position, the USER’s ICS Tie Line will be connected to Bus 1.
When the USER switch is in the BUS 2 position, the USER’s ICS Tie Line will be connected to Bus 2.
3.3.2.1 JA31-N01 for Talk Groups/Isolation
If it is a requirement for
ALL USERS to be able to talk
together on the intercom, all
users' switches must either
select BUS 1 or BUS 2 (i.e. all
switches in the same direction.)
If one user is to be ISOLATED
from the other users, that user
must be connected to a different
bus to all the other users. (i.e.
User's switch must be in the
opposite direction to all the others.)
In this example, User 4 is isolated
from Users 1, 2 and 3.
If it is necessary to SPLIT
the users into Talk Groups, (for
instance Flight Crew and Cabin
Crew) the users' switches
should be connected to different
busses (in this example, User 1
and User 2 are connected on
BUS 2; User 3 and User 4 are
connected on BUS 1.
