9 Local System Access and Management Interfaces
The front panel of the HDX-1100 includes an LCD touch screen that allows radio operating
parameters to be initially configured and later modified by maintenance personnel. The
touch screen provides the ability to recall and review and/or change the frequency of
channel presets, turn the power amplifier on and on, switch between high power and low
power modes, and gives visual feedback to maintenance personnel for each of the
described actions. Future software updates will provide additional set-up capability,
including the ability to set modulation constellation, guard interval, and Forward Error
Correction, and will support saving any changes to a selected or new preset.
NOTE: Both the HDX-1100 touch screen and the RCU remote panel are active and
capable of control when the RCU is powered on. Information shown on the touch screen
will update dynamically if settings on the RCU are changed. Information shown on the
RCU WILL NOT update if settings are changed on the touch screen. The Indications may
be re-synchronized by initiating any change with the RCU, i.e. – preset, channel, etc.
