ALIGN SAME ... : Switch which sets behavior of the main screen ALIGN button.
GROUP: Aligns antennas which belongs to the same SYNC GROUP regardless of the
•
tower assignment. Such setting is suitable for aligning stacks or antennas on different
towers.
GROUP & TOWER: Aligns antennas which belongs to the same SYNC GROUP and
•
have the same TOWER ID. Such setting is suitable for aligning antenna stack while
keeping other antennas on different towers in their directions for multidirectional
beaming.
COUNTER TO ROTATOR ID: Enables counter rotation to the specified ARCO controller
present on the LINK bus. This is a special setting for the ARCO controlled rotator which is
installed over another rotator or on a rotating tower also controlled by own ARCO controller.
COUNTER TO ID number specifies ROTATOR ID number of that controller. This function works
always in pairs and requires SYNC ENABLE option to be enabled in menu and turned ON on
the main screen.
REMEBER SUPERIOR POSITION: For counter rotation ARCO always checks for presence
and position of the superior rotator to show correct position of the subordinated rotator. If
superior rotator is not available (controller for rotating tower is turned off), ARCO normally not
allow to change position of the antenna on subordinated rotator. If this function is enabled,
ARCO can use "last known" superior position from the memory when it was on.
Use carefully! If you move superior rotator while subordinate is off, than turn superior off and
subordinate on, memorized position of the superior rotator in the subordinate controller memory
is no longer valid. Turning superior controller on will automatically fix data mismatch.
