Operation
Front Panel Controls and Indicators
All Digital XPoint controls and indicators are on the front panel (figure 3-1). The
large, illuminated push buttons can be labeled with text and/or graphics. The
buttons can be set to provide amber background illumination all the time or the
background illumination can be set to off. The buttons blink or are fully
illuminated (depending on the operation) when selected. The 8x2 character LCD
indicates the current I/O configuration, preset configurations, the input detection,
and the status of additional system features.
Figure 3-1 shows the DXP 88 SDI. The DXP 44 SDI is identical, with the
exception of fewer input and output buttons. The function of the DXP 44 SDI
is identical, with the exception of the preset number assignments.

Definitions
The following terms apply to Extron matrix switchers, and are used throughout
this manual:
Tie —
An input-to-output connection.
Set of ties —
An input tied to two or more outputs. (An output can never be tied
to more than one input.)
Configuration —
May consist of one tie or one or more sets of ties.
Current configuration —
The configuration that is currently being used (also
called configuration 0)
Global memory preset —
A configuration that has been stored. Up to 16 global
memory presets
can be stored in memory. The input and output buttons
select the desired preset memory location to load or retrieve a preset. When
a preset is retrieved from memory, it becomes the current configuration.
One preset can be assigned to each input and output button. On the
DXP 44 SDI, presets 9 through 16 can only be stored and retrieved via the
RS-232/RS-422 link.
