always active - when the MODE key is depressed and released, the controller's current mode will

change.

The modes are divided into two groups, referred to as mode groups. The Operational mode group

consists of the MANUAL, AUTO, REMOTE, and TRACK modes. The Programming mode group

consists of the SETUP, RESET, DELETE, RE-SYNC, CONFIG, and LIMITS modes. The Programming

modes are typically only used during system installation and configuration. The Operational modes are

the ones used in everyday operation of the controller.

To switch between modes in a group, rapidly depress and release the MODE key. To switch to a mode

in the other mode groups, depress the MODE key for at least five seconds and release. Note that the

Expert Access feature can prevent access to certain modes. See section 2.5 for more information on

the Expert Access feature.

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 that 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.

On power up, either MANUAL, TRACK or LIMITS mode will be active. If the unit powers up and the

azimuth or elevation limits are invalid LIMITS mode will activate. If the unit powered down while

tracking an inclined orbit satellite TRACK mode will receive control. For all other cases MANUAL mode

will be active on power up.

Here is a summary of the modes implemented on the RC2000C ...

MANUAL

AZ: 325 EL: 976 PL:50 H S:635 MANUAL
SAT:SBS 2 97.0 W FAST

In manual mode you can:

1. Jog the antenna in elevation and azimuth using the AZIM CW, AZIM CCW, ELEV UP, and ELEV

DOWN keys.

2. Toggle the speed from fast to slow (and vice versa) with the SPEED key.

When MANUAL mode is active the following information is displayed on the top row of the LCD:

azimuth position (AZ), elevation position (EL), and the current signal strength (SS). The signal strength

is derived from an analog input in the controller’s backpanel.

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 that will be used for jogging

the antenna. When the antenna is being jogged at slow speed the voltage applied to the actuator is

displayed to the right of the SLOW speed banner.

AUTO

SELECT A SATELLITE:PANAMSAT-1 AUTO
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, or

TRACK mode for an inclined orbit satellite.
