When completed, you must save the desired HFO value. Press ENTER several times to select the REMOTE
PARAMETERS display. Press the LEFT or RIGHT arrow key to enter writing mode and then press the ENTER to
save the HFO value in the PCUs NVRAM.
EXAMPLE: In the “Antenna stopped before the Bow” example above, the HFO calculated was 222. To enter
this value:
1. Set the Remote Command value to "
N6222
".
2. Press ENTER to send this HFO to the PCU. The display should now show "N0222".
3. When completed, you must save the desired HFO value. Press
ENTER
several times to select the
REMOTE PARAMETERS
display. Press the
LEFT
or
RIGHT
arrow key to enter writing mode and
then press the
ENTER
to save the HFO value in the PCUs NVRAM.
You have to drive the antenna CW in azimuth until the home switch is actuated, or re-initialize the antenna to
begin using the new HFO value you have entered and saved. To re-initialize the antenna from the REMOTE
COMMAND window of the ACU;
1. Press UP arrow key several times to return to the REMOTE COMMAND display.
2. Press the
LEFT
or
RIGHT
arrow key to enter edit mode. Use the
LEFT
/
RIGHT
and
UP
/
DOWN
arrow keys to set the character and digits to "
^0090
" and then press the
ENTER
key.
This resets the PCU on the antenna. The antenna will reinitialize with this command (Performs a similar
function as a power reset of the antenna) and the new home flag offset value will be used to calibrate the
Relative position of the antenna.
5.5. Radiation Hazard and Blockage Mapping (AZ LIMIT parameters)
This system may be programmed with relative azimuth and elevation sectors (zones) where blockage exists or where
transmit power would endanger personnel who are frequently in that area.
Refer to your ACU Manual for instructions on programming of these zones.
5.6. TX Polarity Setup
With the feed in the center of its polarization adjustment range, observe the transmit port polarity (vector across the
short dimension of the transmit wave-guide).
If the transmit polarity in the center of the travel range is vertical, use the following entries:
2 Vertical Transmit Polarity
4 Horizontal Transmit Polarity
If the Transmit polarity in the center of the travel range is horizontal, use the following entries:
2 Horizontal Transmit Polarity
4 Vertical Transmit Polarity
5.7. TRACK DISP
This parameter set the selections that the user will see in the Tracking - Band Selection menu. Band Selection
must
be
set to the appropriate selection for Tracking to operate properly.
Band selection controls the
local logic output state of SW1 output terminal on the Terminal Mounting Strip PCB and
remote C/Ku relays (or other switches) on the antenna pedestal.
The factory default selections and SW1 status for your 9797B is listed in the following table:
