RC2000A Dual Axis Antenna Controller
the desired satellite using the azimuth jog, elevation jog, polarization jog, H/V, and SPEED keys as
described for MANUAL mode above. The SCROLL UP/DOWN and ENTER keys are also active at this
time. The SCROLL keys are used to scroll through a list of satellite names stored in the controller's
EPROM memory. This is the name which will be assigned to the azimuth and elevation positions and
the polarization values stored in the non-volatile memory. The ENTER key is used to select a value
from the list of satellite names.
When the ENTER key is hit the user is prompted to specify the satellite longitude and the H and V
polarization values for the satellite. If the user wishes to assign a name which is not stored in the
satellite's EPROM memory, the USER entry in the satellite name list may be selected and the operator
will be prompted to enter in an alphanumeric string using the SCROLL UP/DOWN and ENTER keys.
When data for one satellite has been stored into non-volatile memory, the user is prompted to position
the antenna on another satellite and repeat the process.
RESET
AZ: OK
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
circuit detected an over current fault and was disabled. 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 can occur
only on the polarization axis when the unit is configured for a rotating feed. It indicates movement of the
polarization sense pot occurred in the opposite direction from that expected. Any error condition can be
reset by pressing the key designated on the bottom line of the display. Errors are covered in chapter 6.
DELETE
SELECT A SATELLITE: PANAMSAT-1
USE SCROLL UP/DOWN, ENTER TO SELECT
This mode allows the user to delete satellites from non-volatile memory. The SCROLL UP/DOWN and
ENTER keys are active.
RE-SYNC
SELECT A SATELLITE: PANAMSAT-1 RE-SYNC
USE SCROLL UP/DOWN, ENTER TO SELECT
The antenna azimuth and/or elevation position can be corrupted by any number of causes (sensor
failure, lightning strike, faulty shield connection, etc). If there is an error in the position counts, the
controller cannot properly position itself on the satellites stored in non-volatile memory, and the limits
are not valid. In this situation, it is necessary to re-synchronize the controller's internal position counts.
To do this, the operator positions the antenna on a known satellite which has previously been stored in
the controller's non-volatile memory. The user then activates RE-SYNC mode and selects the satellite
with which the antenna is currently aligned using the SCROLL UP/DOWN and ENTER keys. When the
ENTER key is hit, the controller's internal position counts are initialized to the positions which were
assigned to the satellite name when that satellite was stored in non-volatile memory. This restores the
count to the value stored prior to the event that caused the data corruption, and affects all satellites
stored in non-volatile memory.
AZIM SLOW
AZ: 1246 SPEED:165
USE SCROLL UP/DOWN, <>, ENTER TO SET
In this mode the antenna can be moved at slow speed about the azimuth axis through the use of the AZ
CCW and AZ CW keys and the azimuth slow speed code can be adjusted by using the SCROLL
