Mode Access - Dawn CONTROL-1500A Manual

CONTROL-1500A Single Axis Antenna Controller
selected from non-volatile memory. A single resynch will realign all satellites stored in non-
volatile memory.
CONFIG
This mode allows the user to view and enter configuration data into the controller. This data is
stored in non-volatile memory and is used to set certain parameters and enable or disable
various controller options. The following parameters and options are controlled or configured
via data entered into the controller from CONFIG mode:
AutoPol
Remote communication port parameters
Slow Speed control parameter
Polarization control options
Drive system automatic move parameters
In CONFIG mode, the SCROLL UP/DOWN keys are used to select the parameter to be
viewed or modified. Asterisks ('***') in data entry field implies that the present value of the
CONFIG item is invalid. The CONFIG mode item can be modified using the numeric keypad to
key in a new value. For the value to be accepted the entry must be terminated by the hitting
ENTER key. The prompt message on the bottom row of the display provides data entry
instructions. For some CONFIG mode items, one of the two possible data values is displayed
in lower case text. For these items the upper case prompt specifies the default value of the
parameter.
LIMITS
This mode allows the user to set the antenna's logical limits. To set a logical limit the user jogs
the antenna to the position of the desired limit and hits the 7 key. The azimuth CCW limit (as
seen by an observer above the antenna) is set first. After this limit is set the user is prompted
to set the azimuth CW limit. Once the limits are set the antenna cannot be moved (except in
LIMITS mode) to a position that is not within the logical limits. In LIMITS mode the controller
will not detect an antenna jammed condition. When the first limit is set the antenna position is
initialized to 30.
More detailed information is available concerning each of the modes described above in
Chapter 4 of this manual.
