SPAN:
The total range of the rotor in degrees. This value is calculated automatically in the calibration
process and can not be changed directly.
LIMITS:
Software limit switch which sets a "safe zone" for stopping the rotor before it reaches the end of
travel. Five (5) degrees means the rotor will stop five degrees before reaching the physical limit. The
value same value is used at both ends the rotation and applies to both manual and automatic
operation. The limits are represented by the black zones on the ends of the orange operational zone.
STRATEGY: The rotor interface implements one of two strategies for reaching the target azimuth: Accuracy
moves the antenna to the selected azimuth using the "shortest way around." When the target
azimuth is outside the rotor limits (for example, a side mount rotor with a span less than 360
degrees), the rotor will not start. Speed moves the antenna to the target by the shortest route as with
accuracy but if the shortest route to the destination is across the limits, the rotor can turn into the
limits if the limit is within the "compromise" angle.
COMPROMISE: Angle value in degrees used by SPEED strategy.
SENSOR TIMEOUT: Defines value in seconds until sensor must change when rotor is in move. Serves as a
protection against broken sensor or broken sensor wires.
REV. DIR. DELAY: Sets time delay which prevents new rotator movement after the target has been reached. If
BRAKE is used, the brake delay should be longer than reverse/forward delay to prevent unnecessary
brake operation.
TRAIL:
This parameter should be set to the appropriate value if the rotator coasts after the CW or CCW relay
is released and overshoots the target. The controller will turn off the motor early to allow the rotor to
coast to the target.
DEAD ZONE: Sets the value in degrees by which a new azimuth must differ from the current heading before the
controller will move the antenna. If the current azimuth is 270 degrees and the dead zone is 10
degrees a new heading must be greater than 280 degrees or less than 260 degrees before the rotor
will be commanded to the new azimuth. If the dead zone is changed, press and release the encoder
to update the azimuth.
FULL SPAN KNOB: If checked, Station Master's rotary encoder can set an absolute azimuth anywhere withing
the full span of the rotor. Otherwise the encoder operates only in the 0 – 359 degree range.
SLIP CONTROL: If rotor being controlled is prone to slipping (for example in high wind), Station Master can
"hold" the antenna in position if the position sensor follows the antenna slip and the slip control is
enabled. The slip control range is the same as the Dead Zone.
Rotator control from Router
Antenna azimuth can be controlled from Router using these controls:
CW:
Rotator moves clockwise while this button is held.
CCW:
Rotator moves counter clockwise while this button is held.
START:
Rotator moves to the entered azimuth in range from 0 - 359 deg after clicking on this button. While
rotator is moving, clicking the Stop button will stop the movement immediately.
STOP:
Stops rotator movement.
MEMORY buttons: Four memory buttons can be used for quick azimuth selection. Each button can be set to a
custom azimuth and identified with a label up to 4 characters long. Once memories are defined and
stored to Station Master, they can be recalled with the rotary encoder or a PS/2 keypad attached to
the PS/2 jack..
