If you need to manually enter commands into the
antenna (for example, to set up the system for a
Tri-Sat mode), follow these steps to connect your
laptop PC to the ADCU.
NOTE: If you are a KVH-authorized technician, you
can use the KVH Flash Update Wizard instead of
HyperTerminal. Enter commands in the wizard’s
“TracVision Antenna Comms” window.
1. Using a PC serial data cable, connect your
laptop to the DB9 Maintenance port on the
back of the ADCU (see Figure 52).
NOTE: If your computer does not have a DB9 serial
COM port, you can use the USB-to-RS232 adapter
manufactured by IOGear (IOGear part number
GUC232A) or Belkin (Belkin part number F5U257,
F5U109, or F5U409). Windows Vista users should
use one of the Belkin models; 64-bit Windows Vista/7
users should use Belkin #F5U257.
2. Open Windows HyperTerminal (or
equivalent) and establish the following
settings for your COM port (see Figure 53):
• Bits per second: 9600
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None
TIP: To view characters on the screen as you type, set
up HyperTerminal to echo typed characters. Select
“Properties” from the File menu; select “ASCII
Setup” at the Settings tab; then select “Echo typed
characters locally” at the ASCII Setup window.
