5.0 MODES – IN DEPTH DESCRIPTIONS
5.1 Operating Group
Within the operating group of modes exists two high level modes – MANUAL and MENU. The MANUAL
mode allows the user to manually jog the antenna while the MENU mode allows the user to select the
modes that implement the RC4500’s automatic movement features. While in either one of these modes,
a momentary push of the Mode key will transition the RC4500 to the other mode.
5.1.1 Manual Mode
AZ: 179.97 RF: 50 MANUAL
EL: 42.45 SAT:
PL: 30.01 V SPD:FAST UTC
<MODE>MENU <0-9>JOG ANTENNA 14:25:47
In MANUAL mode, the user may jog the antenna in all three axes. A momentary push of the Mode key
will move the controller from the MANUAL mode to the MENU mode.
AZ: (True Heading in Degrees)
AR: (Raw Resolver Angle)
AZ: (Pulse Count / Resolver Digitized Count)
The azimuth field shows a current position value of the azimuth axis. It also shows the status of azimuth
limits (CCW, CW). The azimuth axis may be moved by pressing the Az CCW or Az CW keys.
The value displayed may be changed by the Scroll Up/Angle CT key. The display will rotate between
showing true heading, raw resolver angle and antenna pulse count values.
The true heading value is derived by taking the current heading estimate of the mount and adding the
resolver angle.
EL: (Antenna Boresight Elevation Angle in Degrees)
ER: (Raw Resolver Angle)
EL: (Pulse Count / Resolver Digitized Count)
The ELEV field shows a current position value of the elevation axis. It also shows the status of elevation
limits (DOWN, UP). The elevation axis may be moved by pressing the El Up or El Dn keys.
NOTE: when the azimuth field shows a pulse count value (due to pressing of the Scroll Up/Angle CT key),
the ELEV field will also show the current elevation pulse count. During the other three choices of azimuth
display, the field will show the elevation angle derived from the inclinometer.
PL: (Polarization Angular Position in Degrees)
PR: (Raw Resolver Angle
[ Note: Only displayed when a resolver is used for Polarization position sense.]
PL: (Pulse Count / Resolver Digitized Count) [ Note: Only displayed when a resolver or pulse sensor is used.]
This field shows the current angular value of the polarization axis along with its limits (CCW, CW). This
field will also show if the polarization axis has been placed at a predefined horizontal (H) or vertical (V)
position.
The value of the predefined horizontal and vertical positions depends on whether or not satellites have
been stored using SETUP. If MANUAL was entered following a RECALL operation, H and V will be those
stored for the RECALLed satellite. If multiple satellites have been SETUP, H and V will correspond to the
values for the closest (in terms of azimuth location) SETUP satellite. If no satellites have been SETUP, H
