CARE AND CLEANING
The Smartbar is designed for all-weather outdoor operation. You can clean the dirt off of the
Smartbar by spraying it with a garden hose.
IMPORTANT: DO NOT USE PRESSURIZED WATER TO CLEAN THE SMARTBAR.
TROUBLESHOOTING
No Power
Ensure the Smarbar power cable is securely fastened and wired properly in your
vehicle.
No GPS Position
1. The Smartbar interface cables should be securely fastened and connected to
the correct port on your GPS receiver.
2. In order to operate properly, the Smartbar must receive two messages from the
DGPS receiver. These are National Marine Electronics Association (NMEA)
messages known as $GPGGA (GPS Fix Data) and $GPVTG (Course Over
Ground and Speed), or $GPRMC (Recommended Minimum Specific GNSS
Data). GNSS is an acronym for Global Navigation Satellite System.
3. Ensure the BAUD rate is configured to match the output BAUD rate of your
DGPS receiver. You can set the BAUD rate to AUT, which causes the Smartbar
to automatically synchronize its BAUD rate with the BAUD rate of the GPS
receiver.
4. If using a Raven receiver, the RGL 600 may be used to auto configure the
receiver. In the SYS configuration menu, set GPS to INV.
Erratic Swathing Patterns
Make sure the straight line formed by the ‘A’ and ‘B’ marks is parallel to your desired
swath paths. Ensure that no alarms are present while establishing the ‘A’ and ‘B’
marks.
GPS Alarm
Determine if the alarm is the result of loss of differential signal or a low number of
satellites. Go to the GPS Receiver Position Status screen. This is the second sub-
menu under the Configuration Mode GPS main menu (see page 12 and 13). Normally,
the GPS receiver is in 3D differential mode, and the left side of the screen displays
D3X. If you’ve lost differential, no “D” will be present on the far-left side of the screen.
If the alarm is due to a low number of satellites, the number on the far left side will be
4 or less. If this is the case, trees, buildings, or some other obstruction is blocking your
antenna.
