2.1 External Antenna Connector
Image 3: Optional external antenna port
The TN-202 Compact Flash GPS includes an external port for connecting an active external GPS
antenna for maximum reception of GPS signals. Although the TN-202 has a built-in GPS antenna and
should perform well as is, you may encounter situations where an external antenna would produce
much more favorable results such as when driving downtown among tall buildings, or when the
placement of the PDA unit within the vehicle has a limited or obstructed view to the sky. These types of
situations may warrant the use of an external antenna.
Plug the external antenna with MMCX connector to the plug on TN-202. Place the magnetic external
antenna on the roof of the car (magnet side facedown).
CAUTION:
You must grasp and hold at the antenna connector NOT and put strain on the cable, while you are
connecting or disconnecting the external antenna, as excessive stress to the cable may cause damage
not covered by your limited product warranty.

2.2 LED Fix Indicator
Image 4: LED Indicator
On the left-side of the TN-202 is a small LED, which indicates when the device is initializing a GPS fix
and when enough satellites have been received to produce a GPS fix either in 2D or 3D. From your
GPS software you should be able to see the signal status of whether you are receiving either 2-D
(Latitude and Longitude) or a 3D (Latitude, Longitude and Altitude) fix. If you are not getting the desired
results for GPS signal strength, or adequate satellite coverage using the built-in GPS antenna, you may
want to consider using the included external GPS antenna.

3. TESTING YOUR GPS USING YOUR PDA
The included “GPS Information” test program only supports the Microsoft Windows CE & Pocket PC based PDA
platforms. From you laptop or local PC, run the “GPSinfo.exe” to execute the installation procedure of GPS test
program. You will then transfer the program to your PDA using your personal sync program such as ActiveSync
from Microsoft (http://www.microsoft.com/mobile/pocketpc/downloads/activesync35.asp).
1. Insert the TN-202 into your PDA.
2. Run the GPS test program from “Start → Program files” of the PDA. You can then see the results for detecting
the COM port that the TN-202 is using and to check the GPS output data.
DESCRIPTION OF “GPS INFORMATION” TEST PROGRAM:
1. User must select COM port (CF_CARD-GENERIC)
2. Baud Rate (4800)

4. TESTING YOUR GPS WITH YOUR LAPTOP AND THE PCMCIA
ADAPTOR
Users can use the Hyper Terminal program of Windows to verify that the GPS is actually configured
properly and working.
NOTE: Windows Hyper Terminal for Window 98 can not select COM ports above COM5, If your GPS
is assigned a COM port higher than 5, you will need to test it directly with your map software.
1. Run the “Hypertrm.exe” from “Program → Accessories →Communications → Hyper Terminal”.
2. Select the proper COM port for your GPS device.
3. Set COM port to :
Baud rate: 4800
Data bit: 8
Parity: None
Stop bit: 1
Flow control: None
Assuming that no mistakes have been made in the configuration process there should be data being
displayed in the window, which is confirmation that the communication between the GPS device and
the “Hyper Terminal” software is working properly.

5. INITIALIZING YOUR GPS
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 PDA, or laptop PC, along with
the appropriate mapping software loaded and properly 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 become 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). The LED
indicator will switch from solid ON to a Flashing mode one a GPS fix has been obtained. 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.
NOTE: If viewing RAW GPS data coordinates from a GPS software, which are displaying zero’s
means, indicates that the COM port connection is correct, but the satellite data is not being received yet
(possibly initializing has not yet completed, you may be located in an area with poor satellite reception).
6. USING TRIPNAV
Once the TripNav’s and your personal mapping software have been installed and configured properly,
you can begin to use TripNav navigation system .
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.
7. FAQ’s
Will the TripNav work with other Street Mapping software?
TripNav standard NMEA data for mapping software to use and convert to coordinates and should work
well with any NMEA compliant software on the market today.
How accurate is the GPS?
GPS accuracy can range from 5 to 50 meters. Most of the time the GPS is accurate to less than 15
meters.
Will the TN-202 add a drain to my PDA battery?
As with any peripheral device which is powered by the PDA’s battery, it will cause the battery to
discharge at a more rapid rate that without the device attached. For this purpose, we strongly suggest
that you use a optional cigarette lighter charging cable while traveling and navigating in the vehicle to
eliminate battery drain and keep your PDA’s battery fully charged. An optional vehicle charging cable is
available from your PDA dealer, or from Rayming’s web-site.

TN-202
What is ideal GPS environment?
The GPS requires an open, clear view of the sky. Buildings, covered parking areas, tunnels and dense
foliage can cause the GPS receiver to be unable to get a location fix.
If you are parked in a covered parking lot or near a tall building, it is recommended that you drive away
until you have a clear view of the sky before using the TripNav. You may need to give the GPS a few
minutes to find or get a fix its location.
How do I know if the GPS is ON?
The TripNav must be plugged into your PDA’s Compact Flash or your Laptop to obtain power. In
addition, the TN-202 has a built-in LED indicator that works as follows:
LED OFF: GPS receiver is off (no power)
LED ON (solid): No fix, searching for GPS signals.
LED FLASHING: Position fix established and GPS signals are being received.
Why does the GPS not work near buildings and other tall objects?
The GPS uses satellites in the space to find out where it is. Therefore it needs a clear view of the sky.
Tall buildings and other objects that block the receiver’s view to the sky make it infeasible to determine
your location.
Sometimes the satellites are not overhead but near the horizon. In these cases the GPS must have a
clear view of the horizon.
Why do I get an error message saying “Unable to open GPS Communication with port (COMx)?
Please check your port configuration.”
If you have followed the above installation steps but the GPS device still does not work, try unplugging
the GPS device, close the mapping software and wait for at least 10 seconds, before re-connecting the
GPS device.
Also verify if the COM port was entered in the mapping software correctly. Another possibility is that
you may be in an area where there are no GPS signals available. The GPS receiver must have a view
to the sky and will not work indoors, or in areas of dense foliage. Move to an open area and place the
TripNav receiver in a location that will have a full exposure to the sky. Each time you initialize the GPS
receiver, the device requires a boot-up period which can typically rage from to 8 seconds to 1 minute,
but in areas where the GPS signal is weak, this period may be slightly extended. Please allow an
adequate amount of time for the GPS receiver’s boot-up process to complete before contacting
Technical Support.
