RC1000A Antenna Controller...........................................................6-7 Delete Mode 13
A & B
The function of these buttons is determined by the mode shown in the upper right hand
corner of the display, and is described by the text appearing over them on the display
bottom line.
E
This Softkey is basically an " ENTER " button, which signifies the desired data is on the
display screen, and it should be saved or acted upon. The current function is defined by
the legend directly above the key, in the lower right hand corner of the display.
CW-SKEW
CCW-SKEW
These two buttons adjust the polarization skew in either a clockwise or counterclockwise
direction. The user fine-tunes the horizontal and vertical polarization with these buttons.
The current polarization count will display in the middle of the top line of the LCD display
while these keys are being pressed. NOTE: These keys are disabled when the Auto-
Pol feature is enabled.
6-3 MANUAL Mode
This mode is used to manually jog the antenna's polar axis as well as toggle the polarization
between the H and V values of the satellite in memory closest to the antenna's polar position.
Additionally, fine-tuning the polarization with the CW/CCW Skew keys is possible in this mode.
Fast and slow speeds are selected via the SPEED switch, positioned on the right side of the
RC1000A faceplate. The REMOTE switch must be kept in the MANUAL position for the front
panel keys to be active. Also, the AUTO-POL feature must be off for the CW/CCW Skew and
POL toggle key to be active (see section 6-10). If Auto-Pol is enabled, the legend above the E
key will be RCV: rather than POL:.
Once the unit is programmed, the user can view the arc of assigned satellites simply by jogging
from one limit to the other. When the antenna is within 3
o of an assigned satellite, that satellite
name appears in lower case letters. As the antenna jogs to within 1 o of the satellite, the name
changes to upper case letters, signifying the antenna is close to an established target. Any
satellite names that have not been assigned will not display.
Likewise, as the polarization is within approximately 40
o of the target value, a lower case h or v
appears in the display. The indication changes to upper case (H or V) when the probe is within
10
o . No indication for polarity means the probe is positioned between h and v.
