3. Make sure you see the Pointing Done message on the DAPT2. Do not remove
the DAPT2 until you see the Pointing Done.
The following screens show the progression of pointing on the Terminal Installation
screens.
Coarse pointing refers to pointing the antenna in the general direction of the Jupiter
satellite so that the antenna can acquire the satellite signal. Fine pointing refers to
refining the antenna adjustment to point the antenna as accurately as possible.
Figure 19 shows fine and course pointing in progress. Once pointing is complete,
click Next to continue.

Once you have finished coarse pointing, use the DAPT2 to fine point the antenna.
The Pointing Validation screen, Figure 19, shows the validation in progress.
Ranging occurs when the HT1100 measures the distance to the satellite to calibrate
transmit power and timing. Once ranging is complete the HT1100's transmit and
receive signal are synchronized to the satellite for optimal transport service.
Once the ranging process finishes, registering the modem begins automatically. See
Chapter 5 – Registering and commissioning the satellite modem for details on
registering and commissioning the modem.
1. Remove the DAPT2 and connect the IFL cable from the satellite modem to the
radio assembly. At this point the modem automatically begins the process of
commissioning which includes registering with the NOC, and related activities.
2. Go back inside to complete installation of the modem.
