Step 3 - Configure the Antenna
The antenna now needs to be configured for in-motion use. This
procedure requires a PC with the latest version of the KVH Flash
Update Wizard installed.
a. Connect one end of a PC serial data cable to the DB9
maintenance port, located on the switchplate. Connect
the other end of the data cable to the serial port on your
computer.
TIP: You can purchase a PC serial data cable from KVH
(KVH Part #32-0628-06).
TIP: If your computer does not have a DB9 serial COM port, you can
use a KVH-tested USB adapter. Refer to the Flash Update Wizard’s
Release Notes for more information.
Figure 11 TracVision Switchplate
b. Double-click the KVH Flash Update Wizard shortcut on
your PC’s desktop to start the Flash Update Wizard.
TIP: You do not need to flash the antenna; you will simply type
commands in the Flash Update Wizard’s “TracVision Antenna
Comms” window.
c. Set the switchplate’s POWER switch to the on (up)
position, then turn on the receiver(s). Wait one minute
for system startup.
d. Type HALT then press Enter.
e. Type DEBUGON then press Enter.
f. Type =LSTEST then press Enter.
g. Type EL,300 then press Enter.
h. Type =CALGYRO then press Enter. If a “Scale factor
