1U ACTIVE CONTROL PANEL
GENERAL INFORMATION
Modules may be controlled by means of a local,
front control panel, by a similar panel at a remote
location or a computer interface. Communication is
via a wired network system called RollCall™ and
many units may be controlled.
THE CONTROL PANEL
All operational parameters and selections are
made using a system of menus displayed in two
LCD windows.
Menus are selected by push buttons and further
menu selections made by rotating a spinwheel and
pressing a push button.
The spinwheel also allows continuously variable
parameters, (where applicable) to be adjusted and
the settings seen in the LCD window.
Various specific operations may be achieved by
operating dedicated push buttons.
The Menu System
The system may be considered structured as a set
of menus and sub-menus that are displayed in the
Control window. The
Information
window will
display the current status of the controlled module
and other information messages. (e.g. error
comments, warnings etc.)
The
Control
display contains the names of the
lower-level menus that may be scrolled through
using the spinwheel.
The sub-menu may be then be selected by
pressing the push button adjacent to the
arrowhead in the text line of the menu name.
This sub-menu will then be displayed in the window
and will have the option of selecting another sub-
menu in the same manner, or allow the adjustment
of a particular parameter.
Pressing the
Home
button will display the
Select
Menu
in the control window from any position in
the menu hierarchy.
The
Previous
button allows a return to the last
menu that was changed. Up to 20 changed menus
may be retraced using this function.
The
Return
button will allow access to the
previously selected upper-level menu.
Note that the spinwheel will only be operative when
the
Scroll
green LED is illuminated, indicating that
a menu with more than four text lines is being
displayed. Operating the spinwheel then allows the
other text lines to be displayed.
When illuminated the
Adjust
LED indicates that
parameters of the selected module may be
adjusted.
