RC2000A Dual Axis Antenna Controller
•
If the closest satellite is a hybrid satellite (both C and Ku band) and the two polarization
positions associated with the satellite's data entry in non-volatile memory are DIFFERENT the
displayed polarization codes will again be 'C', 'c', 'K', or 'k'.
SELECT A SATELLITE: PANAMSAT-1
USE SCROLL UP/DOWN, ENTER TO SELECT
Satellites which have been stored in the controller's non-volatile memory (via SETUP mode) can be
recalled with AUTO mode. Azimuth, elevation, and H/V polarization data for up to fifty (50) satellites
may be stored in non-volatile memory. When AUTO mode is activated, the SCROLL UP and SCROLL
DOWN keys may be used to scroll through the list of satellites. Depressing the ENTER key initiates an
automatic move to the selected satellite.
When the antenna is moving to the azimuth or elevation position associated with the selected satellite,
the STOP key may be used to stop the antenna's movement. When this occurs the user is prompted to
select another satellite with the SCROLL UP and SCROLL DOWN keys. If the automatic move
continues to completion and the AutoPol feature is disabled, the polarization will be set to the horizontal
position of the satellite which was the target of the automatic move and the mode will change to manual.
If simultaneous azimuth and elevation movement (see CONFIG mode) is enabled, the antenna will
move about the azimuth and elevation axis simultaneously when performing automatic moves.
Simultaneous azimuth and elevation movement should only be enabled if the total current draw of the
two axes is less than 8 amps under all operating conditions.
NOTE: WHEN THE POWER IS TURNED OFF, THE POLAROTOR PROBE MAY SLIGHTLY SHIFT
POSITIONS. WHEN THE POWER IS RE-APPLIED, THE POLAROTOR PROBE WILL MOVE BACK
TO THE POSITION IT WAS AT BEFORE POWER WAS REMOVED. FOR THIS REASON, ALWAYS
LEAVE THE CONTROLLER ON.

In REMOTE mode the controller will respond to commands received via the built-in RS-422 port.
REMOTE mode can only become active if the 'Remote Mode Enable' CONFIG mode item is enabled
(see CONFIG mode, section 4.10). If REMOTE is enabled via CONFIG mode, it can become active
either in response to the user manipulating the MODE key or upon the reception of a valid command at
the communications port.
Refer to the appendices for a description of the communications protocol. If the AutoPol feature is
active, the 'POL:' banner on the display is replaced with 'RCV:'. When the controller is in REMOTE
mode the only key that is active is the MODE key.
SETUP mode allows a user to store a satellite name, azimuth and elevation antenna positions, and
horizontal and vertical polarization positions into non-volatile memory. Once stored in non-volatile
memory, a satellite position may be recalled via AUTO mode. SETUP mode is only accessible when
the Expert Access Flag is set. See section 2.5 for more information on the Expert Access Flag.
When SETUP mode is activated the following screen is displayed for approximately 5 seconds.
