6 RC2000C Az/El Tracking Antenna Controller
REMOTE
AZ: 325 EL:
SAT:SBS 2
In this mode the controller receives and acts on commands received via the communications port. This
mode can only receive control if enabled via a CONFIG mode item. The only key that is active is the
MODE key, which can be used to switch to a different mode.
SETUP
AZ: 325 EL:
SAT:SBS 2
This mode allows a user to associate a satellite name with an antenna azimuth and elevation position
and to assign horizontal and vertical polarization positions to that satellite. The satellite name and the
antenna position data associated with it are stored in non-volatile memory. Once stored in memory, the
satellite is available for recall by AUTO mode. Note that not all versions of the software support
polarization control.
When SETUP mode is first activated, the user can jog the antenna using the AZIM CCW, AZIM CW,
ELEV UP, and ELEV DOWN keys. On controllers that support polarization control the polarization may
be skewed using the POL CCW and POL CW keys. The user peaks the antenna on the desired
satellite. The satellite name is selected using the SCROLL UP and SCROLL DOWN keys (the selected
satellite name is displayed to the right of the SELECT: banner). If the desired satellite name is not
available select the USER entry to manually enter a satellite name.
When the ENTER key is depressed the user is prompted to enter ...
1. the satellite longitude,
2. whether or not the satellite is in an inclined orbit (and if so, the satellite frequency band and the
current inclination of the satellite's orbital plane to the earth's equatorial plane - more on this in the
chapter on tracking), and
3. the horizontal and vertical polarization values for the satellite (on those versions of the software that
support polarization control).
When the user has entered all of the requested data, the controller will respond with "DATA
ACCEPTED", and the user can jog the antenna to another satellite and repeat the procedure. If the
satellite just entered was an inclined orbit satellite, the controller will activate TRACK mode and will
initiate a track on the satellite.
RESET
AZ: DRIVE
RESET AXIS: 1-AZ, 2-EL, 3-POL
This mode allows the user to examine the error status of the motor drive circuits and reset them if a fault
has occurred. The drive systems of each axis are independent. A DRIVE error indicates that the drive
circuits detected an over current fault and shut down. A JAMMED error indicates that the antenna
actuators were commanded to move but no movement was detected. A RUNAWAY error indicates that
antenna movement was detected when the actuators were not energized. A SENSOR error indicates
backward movement of the polarization sense potentiometer. (Polarization errors will only be shown if
the rotating feed drive option has been enabled.) An error condition for a given axis can be reset by
depressing the numeric key associated with that axis as described on the bottom row of the display.
Errors are described in chapter 7.
