5.2.1 Show Azimuth
Azimuth angle display format:
This angle can assume any value from -180 degree to 540 degrees max, or
within the range of the rotator as set with the MAX and MIN Angle settings
for each motor.
MATH – show angle from -180 degree to 540 degree,
NORMAL – show angle in 0 – 359 degrees.
Example:
MATH ANGLE

-1 degree
-359 degree

5.2.2 Short Way
OFF - Disable Shortest Route feature on AZ Rotators or the azimuth portion
of an AZEL Rotator
ON - Enables Shortest Route feature on AZ Rotators or the azimuth portion
of an AZEL Rotator
5.2.3 Use EL MAP
Use elevation map. This is a map of minimum elevation angles at specific
azimuth angles. This map can be created with the program “spidMD01dde”
(name may change). The map can be used when, for example, high buildings or
trees are around the antenna and obscure visibility.
Example: if USE EL. MAP is set (ON) and you set a minimum elevation angle of
20 degrees for azimuth angles from 10 to 100 degrees, and a satellite
tracking program (like Orbitron) sends the MD-01/02 an elevation angle less
than 20 degree for an azimuth angle in 10 to 100 degree range, the MD-01/02
will only take the elevation angle to 20 degrees.
