KVH Industries TracVision R4 - Manual (Page 52)

4.3 Antenna Gyro and LNB Faults
Section 5, “Maintenance,” provides detailed instructions for
authorized service personnel who may be required to replace
TracVision R5/R4 components.
The TracVision R4 does not include
an antenna gyro.
4.4 Computer Diagnostics
TracVision R5/R4 has been designed to provide diagnostic
readouts on a PC with a RS-232 serial communication port. If you
are unable to isolate a system problem with the foregoing
troubleshooting tools, set up a laptop to carry out computer
diagnostics as described below. System problems should be
found somewhere through the diagnostic readouts.
The procedure requires a PC with Windows HyperTerminal or
download the KVH Flash Update Wizard (available for free at
www.kvh.com/wizard).
1. Connect one end of the PC data cable to the
maintenance port on the switchplate (see
Figure 3-5). Connect the other end to the serial
port on your PC (a 9-pin/25-pin connector adapter
may be needed for some PCs).
2. If you are using HyperTerminal, open it and
establish the following settings:
• Bits per second: 9600
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None
If you are using the KVH Flash Update Wizard,
double-click the “KVH Flash Update Wizard”
shortcut on your computer’s desktop to start the
wizard. Then go to the “Select board to flash”
screen. You do not need to flash the antenna to
configure the satellites; you will simply enter
commands in the
“Command” box.
