RC4500 Antenna Controller Chapter 5 MODES – In Depth Descriptions
86
5.2 Programming Group
The programming group has two high-level modes (CONFIG-MENU and MAINTENANCE). Both of these
modes serve as a menu system for sub-modes below them. Momentarily pressing the Mode key will
switch between these modes in a similar fashion as the MANUAL and MENU modes switched in the
operating group.
5.2.1 Configuration Mode
The CONFIG mode allows users to view and/or modify various controller parameters and to enable or
disable certain features. Many configuration items are used to customize the RC4500 to work with a
particular installation.
The CONFIG mode groups configuration items into screens containing between 1 to 10 individual items.
The top-level CONFIG-MENU allows the user to scroll through the list of configuration item groups. As
the user scrolls through the CONFIG-MENU screens, a group title (line 1) and brief description (line 2) of
group items is presented to identify the set of configuration items to view or modify.
The example CONFIG-MENU screen identifies the AZIMUTH CALIBRATION group. The description “AZ
REFERENCE VOLTAGE/LIMITS/SCALE FACTOR” provides an overview of the type of configuration
items that will be available for viewing and/or modification.
AZIMUTH CALIBRATION CONFIG-MENU
AZ REFERENCE VOLTAGE/LIMITS/SCALE FACTOR
<SCR>THRU LIST <ENTER>SELECT <MODE>MAINT
To move through the CONFIG-MENU list, press the “Scroll Up/Yes” key to advance to the next screen or
press the “Scroll Dn/No” key to move to the previous screen. To select the currently identified group for
viewing/modification, press the “Enter” key and the screen showing the individual items in the group will
appear. Momentarily pressing the “Mode” key will move from the CONFIG-MENU mode to the
MAINTENANCE mode.
If the AZIMUTH CALIBRATION group were selected, the following screen would appear:
CONFIG-AZIM
CCW:-180.000 CW: 180.000
PSF:10431 ROFF:-179.049 DIR:0
CCW LIMIT <+/-300.000 DEGREES>
In this example there are five individual configuration items related to the azimuth axis. To move between
the items, use the “Scroll Up” and “Scroll Dn” keys. The cursor will flash at the beginning of the data field
for the item currently selected. On line 4, a prompt briefly describing the item and showing the valid range
of data will appear. Data may be entered for the item as described in section 2.1.2. Momentarily pressing
the “Mode” key will return to the CONFIG-MENU mode.
The following table lists all the configuration item group titles and descriptions as they appear in the
CONFIG-MENU mode. Details for each group are provided in the following subparagraphs. The table
also shows which configuration item groups are available according to how the Expert Access Permission
(
5.2.1.1.1) is set.
Additional configuration item screens may appear if they are unique to an optional feature (inclined orbit
tracking, remote control, etc). Descriptions of those screens will be provided in their appropriate
appendices.
