Calibration
Two on board trimmers are provided to calibrate the controller.
Note – adjustment of these trimmers which leads to a “fault” is not covered by the warranty.
Please do not adjust them if you are not sure of the correct procedure.
If necessary, you can recalibrate your controller via USB port. See calibration procedure issue.
Off-set
If the initial antenna direction it’s not coincident with the geographic direction, you can fix it manually
using an on board off-set trimmer as well via USB.
Default value: 0
Revers delay
A reverse delay time is provided. This is to reduce stress on your rotator / tower and antenna systems
caused by too-rapid reversal of direction. The default time is 3 seconds, but this may be altered in the
software to suit your antenna system.
Preset delay
A preset delay time is provided. This allows you time to finalise the preset position before the rotator
starts to turn. The default is 3 seconds, which may be altered in the sofware.
PWM duty cycles
This feature controls the accelleration / deceleration of the rotator between rest and full rotation speed.
This feature is kind to your antenna system as it gives smooth starting and stopping of your antenna.
Rotation range
This controller allows you to have 500 degrees of total rotor rotation range with 70 degrees of extra
travel for each side. An on board dip switch allow you to choose between two rotations ranges, 0-500
degrees (default) or 0-360 degrees.
Optimiser
If you select rotation by preset knob or computer control, the optimiser will determine the shortest
direction to target.
Rotor chk
If implemented, if you select a target with preset or computer control, the CPU will check the feeback
signal from the rotator, and within 5 seconds will prevent the rotator from turning in the event of an
abnormality.
