Step 3 - Configure the New Linear LNB
The following instructions explain how to
configure the antenna to use the new linear LNB.
a. Rotate the skew motor assembly until the
LNB's connectors are facing approximately
straight downward. Then, using a digital
level, measure and record the angle of the
LNB, as shown in Figure 9.
b. Reconnect power to the TracVision system.
Then connect a PC to the TracVision system.
NOTE: Connection instructions vary. Refer to the
Flash Update Wizard's Help file for connection
instructions (see Figure 10).
c. Open the Flash Update Wizard. Then turn on
the TracVision system.Wait 2 minutes for
system startup.
d. Type the following commands into the
wizard's "Command" box. Press Enter after
each command.
HALT
DEBUGON
SKEWMTRON
ZAP
e. The antenna will restart. Wait two minutes
for system startup.
f. Type the following commands into the
wizard's "Command box." Press Enter after
each command.
HALT
DEBUGON
EL,0
SKEW,0
g. Using a digital level, measure and record the
angle of the LNB (see Figure 9).
NOTE: The digital level always displays positive
angles. However, the antenna skew mechanism
regards angles clockwise from vertical as negative and
counterclockwise from vertical as positive (see
Figure 11).
