The A, B, C, and U code fields each have a drop-down menu for easier and more accurate

space that reads,
Enter Your Own Value —but do this only if you are specifically instructed
to do so by Hughes Installer Support .
Note: You can clear previously entered installation information by clicking Control
in the screen’s left panel, and then clicking Clear Terminal Install . A message warns
that this operation could make the modem inoperable. (In this message, modem
refers to the satellite router.) Execute this command only if you are confident you know
what to expect. The router reboots, and all fields are cleared.
5. Enter the site latitude and longitude values from your GPS receiver, in degrees and minutes
to three decimal places.
Figure 14: Fields where latitude and longitude are entered
The router’s installation software uses the site latitude and longitude to determine the uplink
and downlink cells to which the router will be assigned and the uplink polarization setting
on the radio assembly (LHCP or RHCP).
You must enter the latitude and longitude in the format shown in Figure 14: Fields where
latitude and longitude are entered on page 22:
• Latitude: DD MM.MMM
• Longitude: DDD MM.MMM
Enter degrees in whole numbers only, with no decimals. Degrees latitude is 1 or 2 digits (0
– 90° north or south). Degrees longitude is 1 – 3 digits (0 – 180° east or west). Examples of
degrees correctly entered:
5 , 05 , 42 or 112
Enter minutes as a whole number plus a decimal fraction to three places (thousandths) with
no seconds. Examples of minutes correctly entered:
7.223
and
34.775
If you type a number with a leading zero, the zero is not displayed after you press Submit
Installation Parameters . For example, if you type 06 it is displayed as 6 .
If you enter the site latitude and longitude incorrectly, the router will report a Probing Failure
and will not be able to uplink to the satellite. Probing refers to the first time the router tries
to transmit back to the satellite.
