1. Connect your GPS receiver to a null modem adapter or cable.
2. Connect the data cable that was supplied with your scanner to the null modem.
3. *The data cable has a DE-9 socket (female) connector. To connect to the data cable, you need a
DE-9 plug (male) connector. (DE-9 connectors are often called DB-9 connectors.)
4. *Depending on your GPS connection and your null modem, you might need a gender changer
and/or a DB-25-to-DE-9 adapter.
5. Connect the data cable to the scanner's data port.
6. When the scanner recognizes the GPS input, it displays a confirmation message and shows the
GPS icon on the display.
7. *If the GPS receiver does not have a lock on the satellites, the scanner displays Searching for
Satellite .
Troubleshooting
If you can't get the scanner to recognize the GPS receiver:
Check the cables. Make sure you have exactly one
somewhere in the connection: a straight-through connection will not work.
Check the receiver's baud rate. Most compatible GPS receivers use a baud rate of 4800 bps, but
it's possible your receiver is using a non-standard baud rate. Set the scanner's baud rate to match
the GPS receiver's.
If the scanner recognizes the GPS receiver but doesn't lockout systems as you expected:
