TN-200

IMPORTANT:

1. You must change the default baud rate setting of your mapping software to 4800 if this is not the

default setting otherwise GPS data cannot be received.

2. Set COM port to :

Baud rate: 4800

Data bit: 8

Parity: None

Stop bit: 1

Flow control: None

3. UN-INSTALL THE USB DRIVER

To uninstall the Prolific USB driver using either of these two methods:

a. START Button > PROGRAMS > PL-2320 USB-SERIAL > UNINSTALLER.

b. From the Control Panel go to ADD/REMOVE PROGRAMS and select “PL-2303 USB-to-

SERIAL”from the list and click on the REMOVE button.

4. INITIALIZING YOUR GPS RECEIVER

Before using your TripNav GPS for navigation (especially for the first time), the receiver must obtain a

local GPS fix (coordinates) of the current position. To do this, take your laptop PC (with your USB

driver and the mapping software loaded and configured) to an open area that has a clear view to the

sky (such as a park or empty field). Start your street map software and wait for initialization of the GPS

to complete. This may take a few minutes depending on various factors such as the distance of the

current coordinates from the last time the GPS receiver was activated, GPS signal strength and

surrounding terrain (tall trees and buildings can block the satellite signals). Once the RAW GPS data is

displayed onto the screen, or a fix has indicated that initialization is complete (this will depend on the

actual software being used). In some cases initialization can take up to several minutes depending on

the conditions mentioned above before complete GPS data will be displayed on the screen.

Coordinates scrolling with zero’s means that the COM port connection is correct, but the satellite data is

not being received yet (possibly still initializing or in a bad area for satellite reception).

5. USING THE TRIPNAV GPS RECEIVER

Once the TripNav’s driver and your personal mapping software have been installed and configured

properly, you can begin to use TripNav navigation system by plugging the TripNav into your laptop’s

USB port and launching your mapping software. If you don’t have a mapping, or navigation software to

try out your new GPS receiver, we’ve included a utility called “GPS Information” so that you can test the

function of your TN-200. This utility is located within the “GPS Test” directory on the CD-ROM or can

be download from our web-site.

Always select an area in the vehicle where the GPS unit will be secure and not obstruct normal driving,

visibility and safety, but still maintaining a “view to the sky” in order to receive satellite data.
