Introduction
This chapter describes the screens and menus associated
with the TxPORT PRISM 3000 front panel LCD interface.
The ‘Terminal Operation’ chapter discusses the screens and
menus associated with the external terminal interface. In
general, the options are the same for both interfaces.
The
illustration on this page
depicts the front panel which
has three LED indicators, an LCD screen, and five control
buttons. The
table below the illustration
is referenced by
number to the front panel controls and indicators along with
a brief description.
NOTE: Throughout this manual, all the factory default
settings are shown underlined.
3.1
Front Panel Operation
After power is applied and the unit performs a self test, the
idle display screen appears as
shown in the illustration
below
. The top display line is text that may be user pro-
grammed (see ‘User Info’,
). The
bottom line displays the unit serial number and the
hardware/software revision numbers. The unit may be
accessed by pressing any front panel key.
3.1.1
Maintenance Reset
The PRISM 3000 provides non -volatile memory retention
of unit configuration in the event of power failure. This fea-
ture allows the unit to automatically restore normal service
following a power loss. Note, however, that when the unit is
stored without power for an extended period, the battery
may drain and some parameters may become corrupted.
Therefore, when the unit is first received for installation or if
power has not been applied for an extended period, a factory
default ‘maintenance reset’ operation should be performed.
This is done by pressing and holding the ‘
’ button
and then applying power to the unit. Hold this key until the
‘
RAM
CLEARED
’ message appears. This procedure installs
the predefined ROM configuration to eliminate the possibil-
ity of data corruption. The battery is fully charged after
power has been applied for 160 hours.
NOTE: The maintenance reset operation sets all
parameters to the factory default ROM settings and
zeros all performance registers.
