Model 2090 Parameter List

Model 2090 Multi-Device Controller

Refers to two different tower corrections, depending on the tower
type:

For a standard tower, this value represents the polarization offset, in
the range of

±50 cm, applied to the tower position reading when the

polarization is changed. This parameter allows for correction of the
antenna height changed caused when centerline rotation is not
available or not in use.

For a bore sight tower, this parameter is used to enter the bore sight
separation distance corresponding to the configuration of the tower.
This value can be 3, 10, or 30 meters, and configures the 2090 to
correct for the difference in height between the carrier position and
the actual antenna position.

For bore sight towers, refers to the bore sight mast height correction:

0 = Standard bore sight towers
1 = Custom or alternate bore sight tower

Currently, all six-meter tall 2070 series bore sight towers use the
default correction table. The alternate selection provides a correction
table for a shorter five-meter tower with a different cam mechanism.
In future revisions, the 2090 may provide support for other bore sight
tower designs either by adding additional tables or by allowing the
user to download the appropriate correction table for the attached
tower.

For turntables, refers to turntable rotation mode:

0 = Continuous
1 = Non-continuous

In the continuous mode of operation a turntable is allowed unlimited
movement. The counter readout is from 0 to 359.9 and the software
limits are ignored in this mode of operation. This is the desired
setting for reverberation paddles.
NOTE: For turntables equipped with hardware limits, they must be
disengaged for this mode to work correctly.

In the non-continuous mode, the turntable motion is restricted
between the upper and lower software limits. These limits are
adjustable between –999.9 to 999.9.
