Figure 17: Terminal Pointing Info screen
If you want to change any of the values you previously entered on the Installation Parameters
screen, click
Modify Installation Parameters . This returns you to the Installation Parameters
screen.
Do not click the Abort Pointing button. This would skip the pointing phase and subsequently
cause registration to fail. Then you could only register the router by obtaining a pointing
override from the NOCC. The
Abort Pointing button is used only during manual IDU (router)
replacement, for which the NOCC explicitly approves an antenna pointing override for the
site.
Note: At this point, prior to antenna pointing, the SQF value may be 0, indicating that
the demodulator is initializing, or 1, indicating that the demodulator is searching for a
beacon signal. Most of the time the SQF value is 1 until the demodulator acquires the
beacon signal; then it is > 1.
7.
Make a note of the values shown in the
Computed Parameters
area of the Terminal Pointing
Info screen:
• Azimuth
• Elevation
• Tilt angle
• ODU polarization setting (LHCP or RHCP)
You will need the azimuth and elevation values to point the antenna.
Note:
When you install the antenna, be sure to set LHCP or RHCP as indicated on the
Terminal Pointing Info screen (Setting for ODU Polarization). If you set polarization
incorrectly—for example, LHCP when RHCP is specified—the satellite router will not
receive a signal.
For explanation of the information in the Terminal Info section (lower part) of the Terminal
Pointing Info screen, see
Table 7: Parameters in Terminal Info section (appears on two
installation screens) on page 37.
