that a Polarotor is present in the system. A Polarotor is a servo type polarization control device which
works in an open loop fashion - the controller does not know if it is connected to a Polarotor or not. For
this case the user must still specify H and V polarization positions. Any valid polarization positions may
be specified. An invalid polarization position is one that is outside of or at the CCW and CW limit
positions. If the CW or CCW banner is displayed to the right of PL: use the POL CCW or POL CW keys
to jog the polarization off of the limit.
If the satellite being set up is in an inclined orbit, the controller will prompt the user to specify the initial
track polarization with the following message.
INITIAL TRACK POL (H OR V)?
At this point the user should select either H or V as the polarization to use for tracking when control
switches to TRACK mode. When the user has selected the initial polarization, the 'DATA ACCEPTED'
message will appear for a few seconds, and control will switch to TRACK mode.
If the satellite just entered was not an inclined orbit satellite, after the 'DATA ACCEPTED' message
appears the controller remains in SETUP mode. Control transfers to the initial screen, and the process
may be repeated. Note that the MODE key may be pressed at any time to exit the mode that is
currently active.
User-Defined Satellite Names
If the desired satellite name is not in the controller’s EPROM memory, you can assign a new name of
up to ten (10) alphanumeric characters (A-Z, 0-9, hyphen (-), or space) by accessing the USER entry
mode as follows.
From the screen which allows the user to jog the antenna in azimuth and elevation to peak up on the
desired satellite, use the SCROLL UP/DOWN keys to bring up the 'USER' entry in the list, and press
ENTER. The following screen will be displayed:
SELECT:* KEY IN SAT NAME SETUP
USE SCROLL UP/DOWN, BKSP & ENTER KEYS
Note that the cursor will be displayed under the '*' character. The SCROLL UP and SCROLL DOWN
keys may be used to select alphanumeric characters (A-Z, 0-9, hyphen (-), and space). A space can be
entered in the name by depressing SCROLL UP key once, and SCROLL DOWN key once, and then
ENTER (from the ‘*’ prompt). The BKSP key may be used to delete the character to the left of the
cursor. During alphanumeric data entry, the ENTER key has two functions. If the ENTER key is
depressed while the '*' character is displayed, the alphanumeric data entry session is terminated. If the
ENTER key is depressed when the '*' character is not displayed, the cursor will advance to the right one
space and the user will be prompted again with the '*' character. If the ENTER key is depressed when
the cursor is in the tenth character position of the satellite name data field the entry is terminated.
5.7 RESET Mode
The RESET mode is used to display azimuth, elevation, and polarization drive fault conditions, and to
re-enable the drive outputs in the event the microcontroller has disabled an axis. When RESET mode
is activated, one of the following screens will be displayed.
AZ: OK EL: OK RESET
RESET AXIS: 1-AZ, 2-EL
AZ: OK EL: OK PL: OK RESET
RESET AXIS: 1-AZ, 2-EL, 3-POL
The first screen will be displayed if Rotating Feed Present CONFIG mode item is set to 0, the second
screen will be displayed if the Rotating Feed Present CONFIG mode item is set to 1. There are not fault
