DAC-03 Tracking Antenna Controller Operation
2-3
Special Keys -
UP Arrow - Steps the selected entry UP one increment per sequential key-press or rapidly
increments the selected entry when pressed & held. Affects all Numeric entries and is used to
toggle Tracking ON/OFF, turn Searching ON or to clear the Error display.
DOWN Arrow - Steps the selected entry DOWN one increment per sequential key-press or rapidly
increments the selected entry when pressed & held. Affects all Numeric entries and is used to
toggle Tracking Band selection, turn Searching OFF or to clear the Error display.
N/S/E/W - Toggles North/South Latitude entry, East/West Longitude entry, Tracking Receiver
Input selection and Polarization mode (depends on POL TYPE parameter setting). It is used to make
numeric entries to cause them to become negative values. When in MODE menus the N/S/E/W key
steps the display back UP to the previous sub-menu.
ENTER - Enters the value that has been keyed in.
Status LEDs
TRACKING
- (Green LED)
ON
indicates that the ACU is Tracking a satellite signal whose AGC value is greater than the
Threshold value. The ACU is actively issuing small azimuth & elevation position
adjustments to the antenna to optimize the signal level (AGC). If the system was
Searching, SEARCH will go OFF when TRACKING turns ON.
Blinking indicates that the satellite signal AGC value is less than the Threshold value and
the ACU is counting down “SEARCH DELAY” (seconds). If the AGC does not rise above the
Threshold before the count-down is completed, the ACU will automatically start a SEARCH
to acquire a signal that is greater than Threshold. When SEARCH is ON, TRACKING will be
OFF.
OFF
indicates that Tracking is OFF. This may be due to the operator turning Tracking OFF
intentionally or that Tracking was pre-empted by SEARCH.
SEARCHING
- (Green LED)
ON indicates that the ACU is Searching for a satellite signal whose AGC value is greater
than the Threshold value. When a satellite signal is found SEARCH will go OFF and
TRACKING will come ON. If an adequate satellite signal is not found during the Search,
SEARCH will blink as the antenna re-targets to the desired satellite. If an adequate satellite
signal is still not found, then TRACKING will begin flashing (count-down) until the next
SEARCH is automatically started.
Blinking indicates that the antenna is TARGETING to the calculated Azimuth & Elevation
positions of the desired satellite (SAT). When the antenna arrives at the calculated position
SEARCH will go OFF. If an adequate satellite signal is found at the targeted position
Tracking will commence. If an adequate satellite signal is not found at the targeted
position, TRACKING will begin blinking (see above) until the next SEARCH is automatically
started.
OFF indicates that SEARCH is OFF. This may be due to the operator turning Search OFF
intentionally or that Tracking has pre-empted SEARCH.
UNWRAP - (Red LED) Your system does not require UNWRAP, therefore, this LED should never be
ON.
ERROR - (Red LED)
ON indicates that one, or more , discrete system errors have occurred. Refer to MODE
information menus below to determine which error(s) have occurred.
OFF indicates that no errors have occurred.
RESET - Resets the processors inside the ACU. This does NOT reset the antenna pedestal.
