RC4600 ACU Board Set
2.1.1.2 Front Panel 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 RC4600's automatic movement features. While in either one of these modes,
a momentary push of the Mode key will transition the RC4600 to the other mode.

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.

The azimuth field shows a current position value of the azimuth axis. It also shows the status of azimuth
limits (STOW, CCW, CW). The limits will be displayed based on the table below. It is possible for
different limits to have different sources (Switch Hardware for stow and Pot Based for CCW and 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 local horizontal relative (AZ), true heading horizontal relative (TH), magnetic heading horizontal
relative (MG) and platform relative (az) values.
The local horizontal relative azimuth angle is calculated by taking the current platform relative azimuth
and elevation angles along with the pitch and roll of the mount. If there is currently no mount pitch and
roll. The local horizontal relative azimuth angle will display the same value as the platform relative
azimuth angle.
The true heading horizontal azimuth angle is derived by taking the current heading estimate of the mount
(see the LOCATE function) and adding local horizontal relative azimuth angle and the magnetic variation
for the current location. If there is currently no mount heading estimate, the field will display "********". If
the current heading estimate has not been "fixed" (either manually or automatically by the DVB receiver
function), the field display th: instead of TH: to indicate that the heading value may be inaccurate due to
compass error.
The magnetic heading horizontal azimuth angle is derived by taking the current heading estimate of the
mount (see the LOCATE function) and adding local horizontal relative azimuth angle. If there is currently
no mount heading estimate or lat/lon, the field will display "********". If the current heading estimate has
not been "fixed" (either manually or automatically by the DVB receiver function), the field display mg:
instead of MG: to indicate that the heading value may be inaccurate due to compass error.
