14 RC2000A Dual Axis Antenna Controller Chapter 2 Basic Function
Figure 2.2
MODE
This key is used to select the current mode of the controller. See the description of the various
modes in the next section. This key is always active. Depressing this key will always cause a
mode change to occur. This key is acted on when it is released. If the key is briefly depressed
and released the controller mode will change to the next sequential mode of the mode group
which is currently active. If the key is depressed for at least five seconds and then released,
the current mode will change to the first mode of the mode group which is not currently active.
SCROLL UP/SCROLL DOWN
These keys scroll up or down through a list of items. These keys are used when selecting a
satellite from a list of satellites, selecting a data item to either view or modify, and when
selecting alphanumeric characters for a user specified satellite name in SETUP mode.
YES/NO
These keys are used to supply an answer to a YES or NO question.
ENTER
This key is used to select an entry from a list, terminate a prompt for some action by the user, or
to complete the entry of numeric data.
0-9/DECIMAL POINT (with the stop key)/BKSP
These keys are used for numeric entry. The BKSP key causes the cursor to move one column
to the left writing over the character which was there. In some modes, the BKSP key is used to
prompt the user to confirm that a critical parameter is about to be changed.
SPEED
This key toggles the speed from fast to slow and vice versa.
ARROW KEYS - 2/4/6/8
These keys are used to manually jog the antenna in some modes. The AZ CCW and AZ CW
arrow keys jog the antenna ccw and cw in azimuth, respectively, while the up and down arrow
keys jog the antenna up or down in elevation. Small type within the red arrow indicates
compass direction for antennas installed in the northern hemisphere.
E/W/N/S
These direction keys, E east, W west, N north, and S south are used to specify a direction when
the user is entering latitude or longitude data. These coincide with the arrow keys above.
POL CCW/ POL CW/ H/ V
These keys control the polarization. The POL CCW and POL CW keys skew the polarotor
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 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.
