2.4 Peak/Lock Method (con’t)
Example: 1022 is a decimal word and will set the following condition for
acquisition of the Reference and Data Satellite:
1022 = When the antenna is scanning for the Reference satellite, it will
use the frequency from the Reference Satellite Page (2.3). Alternatively,
if the digit is set to 0, the antenna will scan for the Reference Satellite
using signal strength.
1022 = 0 the AGC circuit of the internal receiver is used for a satellite lock
indication. If the digit = 1, the lock indication is a combination of AGC and
SNR (Signal Noise Ratio) readings. If the digit = 2, the lock indication is
from SNR values only.
1022 = This digit sets the condition that the antenna must find either the
primary or the secondary frequency (F1 or F2)
on the reference satellite in order to confirm lock. Alternatively, if the
digit is set = 3, F1 AND F2 will be confirmed in order for the antenna to
lock.

1022 = This digit sets the condition that the antenna must find either the
primary or the secondary frequency (F1 or F2)
on the reference satellite in order to confirm lock. Alternatively, if the digit is
set = 3, F1 AND F2 will be confirmed in order for the antenna to lock. *
If the last digit is set to = 6, the antenna will peak on Satellite B, then swing
to Satellite A. Use this for extreme cases where there appears to be no
transponder on the desired data satellite.
With DirectPoint™ the Lock Method Word can be set to 10000 to enable
peaking on the desired satellite (Sat A or Sat B) without using a Reference
satellite. In this mode the carrier data from the modem is use solely for
acquiring and peaking on the satellite.
LOCK WORDS FOR COMPASS-LESS ACQUISITION & DIRECTPOINT
COMBINATION
10000 – Normal scan w/compass
