<p><font color="#0000FF"><b>External GPS Receivers</b></font></p>
<p>Cables to connect the CE device direct to a GPS are difficult to obtain for most
devices.</p>
<p>You can use the standard CE device cable and the GPS cable which you use with a PC.
Since both cables are designed to connect to a PC you need to purchase or make a short
cable to join the 2, this is sometimes called a NULL modem cable and simply swaps pins 2
and 3 over. </p>
<p>Below is a wiring diagram for 9 pin connectors</p>
<ul>
<li>Pin 5 (Gnd) is connected through. </li>
<li>Pin 2 and Pin 3 cross-over. </li>
</ul>
<p>For the standard 9 pin connector (DB9) these are the pins.</p>
<p><img border="0" src="ozice_null_modem.gif" width="210" height="127"></p>
<p><b>Configuration</b></p>
<ul>
<li>Configuration of OziExplorerCE is done from the <b>"Configuration</b> /
<b>NMEA (GPS)"</b>
option on the File Menu. </li>
<li><strong>Baud - </strong>The must be <strong style="font-weight: 400">set to the same Baud rate you are
using in the GPS</strong>. Use as high a Baud rate that is possible. Baud Rates from
1200 to 115200 can be selected in OziExplorerCE. <strong>The default is 4800.</strong> If you do
not know the Baud rate of the GPS you are using try <b>4800</b> as this is the standard
for NMEA output.</li>
<li><strong>COM Port - </strong>Select the COM Port you have your
GPS connected on. Normally you will be connecting the external GPS to the
standard serial port provided </li>
<li><strong>Sentence - </strong>Communications for Moving Map operation, to get
the position from the GPS, are made via standard NMEA sentences. Other sentences
may also be used to obtain additional information not contained in the selected
sentence. </li>
</ul>
<p><b>If your GPS outputs the GPRMC sentence then this is the preferred
sentence to select.</b></p>
<p>Read the "GPS Receivers" section of the PC OziExplorer Help for more
information. </p>

<p><b><font face="Times New Roman">1. Install the SmartPath drivers</font></b></p>
<p>
<font face="Times New Roman">Install the SmartPath GPS software
which comes with the Navman sleeve. This will install the driver to configure the
port the Navman GPS uses. The driver creates a serial port which
OziExplorerCE uses to communicate with the Navman.</font></p>
<p><font face="Times New Roman">You should also download and install the latest drivers from NAVMAN's
website.</font><p>
<b><font face="Times New Roman">2. Configure OziExplorerCE</font></b></p>
<p><font face="Times New Roman">Configure OziExplorerCE - using the menu options File / Configuration / NMEA (GPS)
</font>
<ul>
<li>
<p><font face="Times New Roman"><strong>Port</strong> - </font>The Navman GPS sleeve can set itself as COM4 or
COM5 but there is a also port called <b>"Navman"</b>, if you are using a Navman
and select this port
OziExplorerCE will determine the correct com port automatically.</li>
<li>
<p><font face="Times New Roman"><strong>Baud Rate</strong> - set to 57600</font></li>

<li>
<p><font face="Times New Roman"><strong>Check Valid</strong> - can be set either way but be aware of the difference of
operation you can expect. If ON - the Valid flag in the sentence from the GPS will
be checked and if the GPS indicates that it does not have a valid fix, OziExplorerCE will

not have a valid fix.</font></li>
