RC2000C Polar Tracking Antenna Controller
To switch between modes in a group, press the MODE key and release. The new mode will display in
the upper right hand corner of the display. To switch to the other group of modes, hold the MODE key in
for five seconds and release. This scheme was designed to help keep inexperienced personnel from
inadvertently changing any of the programmed parameters specified during system setup. It is also
recommended that Expert Access be used to safeguard the integrity of the data (see section 2.5).

Mode Descriptions

The mode system on the RC2000C antenna controller resembles the menu system used with many
personal computer (PC) programs. On a PC program a menu system allows the user to perform
operations or to enter in data. The user must navigate through the menu structure to the particular menu
which allows access to the function or data that the user wishes to manipulate. On the RC2000C the
mode which is currently active is always displayed in the upper right hand corner of the LCD. Here is a
summary of the modes implemented on the RC2000C.
MANUAL
AZ:159.4 EL: -327 PL: 723 H S:635 MANUAL
SBS 2
In manual mode you can:
1. Jog the antenna in elevation and azimuth using the ARROW KEYS
2. Toggle the speed from fast to slow (and vice versa) with the SPEED key.
3. Jog the polarization with the CCW/CW keys.
4. Use the H/V keys to toggle between the preset H and V polarizations of the satellite which was the
last target of an AUTO move.
When MANUAL mode is active the following information is displayed on the top row of the LCD: azimuth
position (AZ), elevation position (EL), polarization position (PL), and the current signal strength (SS). The
signal strength is derived from a receiver automatic gain control (AGC) output.
The bottom row of the LCD displays the name and longitude of the satellite that was the last target of an
AUTO move, and either the FAST or SLOW banner to indicate the speed which will be used for jogging
the antenna.
AUTO
SELECT A SATELLITE: PANAMSAT-1
USE SCROLL UP/DOWN, ENTER TO SELECT
This mode allows the user to automatically position the antenna on any satellite that has been
programmed into memory. The list of programmed satellites is reviewed via the SCROLL UP/DOWN
keys, and the ENTER key initiates the automatic move. The STOP key will terminate the move. When
the antenna is positioned, the controller will switch to MANUAL mode for a geostationary satellite, and
track mode is activated for an inclined orbit satellite.
REMOTE
AZ: 1291 EL:
SAT: SBS 2
In this mode the controller receives and acts on commands received via the communications port. This
mode can only receive control if enabled via a CONFIG mode item. The only key which is active is the
MODE key, which can be used to switch to a different mode.
