RC2500 Antenna Controller

Chapter 2

Basic Function Description

E, W, N, S

These direction keys, E east, W west, N north, and S south specify a direction when entering

latitude or longitude data.

POL CCW, POL CW, H, V

These keys control the antenna polarization. The CCW and CW keys skew the polarization

control device counterclockwise and clockwise. The H and V keys are used to either select or

specify the polarization position associated with a given satellite. Note that via CONFIG mode

the user can specify the type of polarization control present in the system: none, single port, or

dual port (simultaneous H and V).

STOP

During automatic moves this key may be used to halt the movement of the antenna.

Note that all of these keys are not active simultaneously. The function of each key is dependent on the

current mode of the controller. In some modes certain keys are ignored.

Changing Modes with the MODE Key

The controller’s current mode is always displayed in the upper right hand corner of the controller’s

display. The user can switch the current controller mode by use of the MODE key. The MODE key is

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. TRACK Mode is only available on the

RC2500B model. The Programming mode group consists of the SETUP, RESET, DELETE, and

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

The Operational modes are 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 group of modes, 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 RC2500 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 RC2500 the mode

which is currently active is always displayed in the upper right hand corner of the LCD.

On power-up, either MANUAL or TRACK mode will be active. If the RC2500B unit powered down while

tracking an inclined orbit satellite TRACK mode will receive control, otherwise MANUAL mode will be

active on power up. The RC2500A always powers up in MANUAL Mode.

Here is a summary of the modes implemented on the RC2500 ...

MANUAL

A: 120.77 E: 71.25 P: 174.7 S:635

MANUAL

SAT: SBS 2 97.0 W SPEED:FAST

In manual mode you can:

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

DOWN keys.

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

7. Toggle the signal strength display using the SCROLL UP and SCROLL DOWN keys to show the

voltage at AGC Channel 1 (displays 1:###), the voltage at AGC Channel 2 (displays 2:###) or the

stronger of AGC1 or AGC2 (displays S:###).
