IDU Touchscreen Last State Displayed
When power is reapplied to the IDU, most of the con fi guration options of the
NewS
tream
IDU return to the last operational state, although there are a few exceptions
to this rule. In general, RF energy is not applied upon startup in order to protect
downstream ODUs. Instead, any state variables that control RF energy default to the
powered down state. All other options retain the last state. The following list describes
the state variables explicitly.
Common variables:
o
Frequency – Save last state
o
Antenna Polarity – Save late state
o
Antenna Switch – Save last state
o
RF Band – Save last state
Microwave:
o
RF Power [Hi/Low/Adj]– Save last state
o
Power Amp – Always default to off on powerup
Satellite:
o
RF Carrier – Always default to off on power up
o
RF Modulation – save last state
Cellular:
o
Cell Transmit – Always default to off on powerup
IDU Touchscreen States on Startup or Preset Change
When power is applied to the NewS
tream
IDU, the state of each touchscreen and the
associated buttons display the operational state last con fi gured, prior to shut down, with
the following exceptions:
o
The PA On / Off OLED [ENG], or carrier on / off OLED [SNG] are always set in
the off or standby state.
o
The Cellular On / Standby button is always set in the standby state.
o
The 5” touch screen always starts at the default main screen [as shown
in the cover photograph].
o
When an ENG or SNG preset is selected and initiated [you must press the
Apply
button on front panel to initiate] the Power Ampli fi er [PA] or Carrier [CW] OLED
will return to the standby state.
o
When a frequency is selected and initiated, the PA or CW OLED will return
to the standby state.
