3.2 Operation from Front Panel
Front-panel
layout
The Unity 4600 front panel (3.2) includes the following four main parts: a liquid crystal
display (LCD), six pushbuttons, eight LED indicators, and the front-panel audio and video
monitor ports. Essentially all control available through the network or terminal is also
available from the front panel.
The front-panel LCD (1, see LCD screen relationships on page 29) supports unit
monitoring and control by displaying screens containing status information, menu navigation
pointers, and parameter input fields. Each LCD screen has a label or heading on the first
row and information, parameters, or prompts on the second row which may cycle through
multiple messages depending on the context.
The six pushbuttons (2) are your means of commanding the Unity 4600 from the front panel.
Use the four arrow buttons to navigate through menu screens and parameter selections and
to scroll through available choices or characters when editing an input field. Press the
ENT
(Enter) button to select menus (downward navigation), to open editable input fields, or to
commit edited parameters to the
Unity 4600. Press ESC (Escape) to exit an input field
without saving the entry or selection.
ESC also provides upward navigation through the
menu structure to the home screen.
The eight front-panel LEDs (3) provide status information about your Unity 4600 and its
processes. See
Table 3.2: Front-panel LED Indicator Descriptions on page 33 for complete
details. (Two additional LEDs are located on the rear panel and provide Ethernet status
indications.)
At far right are the video port and audio port (4) included for monitoring from the front panel.

LCD screen
relationships
Figure 3.3 shows LCD screen relationships from the top level downward. These screens are
structured in two dimensions, reflecting their relationships as peers, as parents, and as
children of other screens. The up-and-down dimension represents the parent-child screen
relationships (navigated with the
ESC and ENT buttons). The side-to-side dimension is the
peer relationship (navigated with the right- and left-arrow buttons). A parent screen is
usually a menu screen covering some category of
Unity 4600 operation or status. Its child
screens are opened by pressing
ENT at the parent screen. These child screens then
provide access to finer details of unit monitoring and control. Multiple child screens of a
parent menu screen are all peers to each other. However, the most significant set of peer
screens are the top-level screens that have no parent and that include the home screen.
The home screen may be reached by pressing and holding ESC (or pressing it repeatedly) from
any other LCD screen
. Appendix A Monitoring and Control Details gives more details on
screen types and using front-panel push buttons to navigate and control the Unity 4600.
