Chapter 2 — Building GPS <strong>Data</strong> Cables and Power Cords<br />

finished.<br />

Testing<br />

You should always test your cables before first use to ensure that there are no short circuits or<br />

bad connections. Use a multimeter to do this, as shown in Figure 2-15. Make sure that each<br />

pin on the GPS connector corresponds to the appropriate pin on the 9-pin connector. Also<br />

ensure there are no short circuits to any other pins.<br />

Refer to your multimeter’s user manual for details on how to operate it.<br />

After testing, you can connect the GPS to your PC.<br />
