Changing Modes With The Mode Key - RESEARCH CONCEPTS RC2000C Manual

4 RC2000C Az/El Tracking Antenna Controller
MODE
This key allows the user to change the controller's current mode. Modes are used to access
the various functions of the controller. For example, when MANUAL mode is active the user
can manually jog the antenna; when SETUP is active the user can program satellite position
data into the controller's non-volatile memory. The modes are divided into two groups:
Operational Modes (which include MANUAL, AUTO, REMOTE, and TRACK modes) and
Programming Modes (which include SETUP, DELETE, RESET, RESYNC, CONFIG and
LIMITS modes). To change from one GROUP to the other DEPRESS THE MODE KEY FOR
AT LEAST FIVE SECONDS AND THEN RELEASE IT. To toggle between the modes in a
given group rapidly depress and release the mode key.
SCROLL UP, SCROLL DOWN
These keys are used to 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 type 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 that 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 Az/El speed from fast to slow and vice versa.
AZ CW, AZ CCW, UP, DOWN
These keys are used to manually jog the antenna in certain modes. CW refers to clockwise
and CCW refers to counter clockwise. The sense of azimuth rotation is as seen by an observer
located above the antenna. On early versions of the controller the AZ CW, AZ CCW, UP, and
DOWN labels were not present on these keys. On these controllers (when certain modes are
active) the left arrow key initiates CCW azimuth movement, the right arrow key initiates CW
azimuth movement, the up arrow key initiates up elevation movement, and the down arrow key
initiates down elevation movement.
E, W, N, S
These direction keys, E east, W west, N north, and S south specify a direction when the user is
entering latitude or longitude data.
POL CCW, POL CW, H, V
These keys control the antenna polarization. The POL CCW and POL 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 not
all versions of the software support a polarization control device.
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.
2.2
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
