Compatible GPS receivers
You can connect your scanner to any GPS receiver that meets the following criteria:
- Outputs NMEA-0183 v3.01-compliant location data
- Outputs both the Global Positioning System Fix ( GGA ) and Recommended Minimum Specific GNSS ( RMC ) data sentences
- Provides a serial data (RS-232) connection
Configuring your scanner
- Go to the Settings menu and select Set Serial Port .
- Select Set Baud Rate.
- Select Set Rear Port.
- Select 4800 bps for the baud rate.
Connecting the receiver
- Plug your GPS receiver's RS232 cable directly into the DB9 connector on the back of the scanner.
- When the scanner recognizes the GPS input, it displays a confirmation message and shows the GPS icon on the display.
- If the GPS receiver does not have a lock on the satellites, the scanner displays Searching for Satellite .
If you can't get the scanner to recognize the GPS receiver:
- 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.
- Check the receiver's output mode. Some receivers have proprietary signalling modes that are not NMEA compliant, but you can usually set them to use a NMEA compliant mode.
If the scanner recognizes the GPS receiver but doesn't lockout systems as you expected:
- Make sure the GPS receiver has a lock on the satellites.
- Check the location configuration for the sites and channel groups in the system.
- For each site or channel group, go to the Set LocationInfo menu.
- Check the range, latitude, and longitude settings to make sure they are correct.
- Make sure the Set GPS Enable option is set to Yes .
