Azimuth and Elevation Slow Speed Codes

The Azimuth and Elevation Slow Speed CONFIG items can be used to set the azimuth and elevation
slow speed codes. Please refer to section 3.5 for more information on the slow speed system. The
range of values for these parameters is from 1 to 254. Higher numbers give faster speeds. (For a given
axis, a slow speed code of 254 will disable the slow speed system for that axis - all movement will occur
at fast speed.) For most motor/sensor combinations, a slow speed code in the range of 140 to 175 is
appropriate. If the slow speed codes are changed, test the slow speed system to insure that the selected
values yield reasonable results. Access to these CONFIG mode items are allowed only when the Expert
Access flag is set.

Geo Elevation Position

GEO ELEV POSITION:
0-DISABLE
This parameter specifies the elevation position where the geostationary satellite arc can be tracked with
only azimuth movement. See section 3.6. This parameter must be specified before any inclined orbit
satellites may be programmed into the controller's non-volatile memory.
Use the following procedure to determine this parameter:
1. Adjust the mount so that it will track the geostationary arc with only azimuth movement.
2. Go to CONFIG mode and set this parameter to zero (0).
3. In MANUAL mode, determine the elevation position at which the mount will track the geostationary
satellites with only azimuth movement.
4. Go to CONFIG mode and set the Geo Elev Position to the elevation value found in step 3.

Polarization Motor Option

The RC2KPOL option allows the RC2000C to control a 12 or 24 volt polarization motor with
potentiometer position feedback. If this option is present, a 5 position orange connector will be found on
the upper left hand corner of the back panel. The CONFIG mode items described in this section are
used to configure the controller to work with the RC2KPOL option. Access to these CONFIG mode items
is allowed only if the Expert Access flag is set. The Rotating Feed Present item is the controlling item for
access to the other items described in this section.
The Rotating Feed Present CONFIG mode item is used to inform the controller of whether or not a
polarotor is present in the system. If the RC2KPOL option is installed this parameter should be set to
YES (see section 3.3).
ROTATING FEED PRESENT?:1
O-NO 1-YES
The following items set the controller's CW and CCW polarization limits when a rotating feed is installed.
The procedure to determine these limits is given in section 3.3. Note that the CW limit must by definition
be less than the CCW limit.
