Changing Modes With The Mode Key; Mode Descriptions - Dawn CONTROL-1500A Manual

CONTROL-1500A Single Axis Antenna Controller
This key toggles the antenna 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 left and down
arrow keys jog the antenna one direction while the right and up arrow keys jog the
antenna in the other direction.
CCW/CW/H/V
These keys control the 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 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 user can switch the current controller mode with the MODE key. The MODE key is always
active - when the MODE key is depressed and released, the controller's current mode will
change.
There are two mode groups – Operational and Programming.
Operational modes consist of MAN (manual mode), AUT (auto mode), and REM (remote
mode).
Programming modes consist of SET (setup mode), LIM (limits), CFG (config), DEL (delete),
FIX (resync mode), RST (reset mode).
The Operational modes are the ones used in everyday operation of the 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 control-1500 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 control-1500, the mode which is currently active is always displayed in the
lower right hand corner of the LCD. Here is a summary of the modes implemented on the
control-1500A.
