To enter the calculated HFO value, press & hold both LEFT and RIGHT arrows for six seconds to enter the
parameter menu at the EL TRIM parameter window. Press DOWN arrow key numerous times (about 21) until
you have selected the REMOTE COMMAND window.
To Enter the HFO value:
In the REMOTE COMMAND window, press the LEFT arrow key until you have underscored the left most
character in the displayed value (ie the A in "A0000"). Use the UP/DOWN arrow keys to increment/decrement
the underscored character until it is upper case N (“N0000” should appear in the command window). Press
the RIGHT arrow key to move the cursor under the most significant digit, then use the UP arrow key to
increment it to a value of 6 (the display is now “N6000”). Set the three digits to the right of the 6 to the three
digit HFO value from 000 to 255 (corresponding to 0 to 360 degrees) that you calculated above. Use the
LEFT/RIGHT keys to underscore the desired digit(s) then use the UP/DONW arrow keys to
increment/decrement the underscored value. When you have finished editing the display value, press ENTER
to send the HFO value command to the PCU (but it is not save yet).
If you want to find out what the current HFO value is key in N6999 and hit ENTER.
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;
4. Press UP arrow key several times to return to the REMOTE COMMAND display.
5. 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.
4.5. 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.
4.6. 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
