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.
TIP: 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 54).
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 F5U109 or
F5U409).
2. Open Windows HyperTerminal (or
equivalent) and establish the following
settings for your COM port (see Figure 55):
• 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.
