GPS RECEIVER / SMARTBAR COMMUNICATIONS
The Smartbar receives communication messages from the GPS receiver. Using the BPS
screen (
Configuration Mode - SYS), you can select a BAUD rate for communicating with the
GPS receiver and monitor certain data communication and message conditions:
If the top center green LED is on or flashing, but the middle-center and bottom-center green
LED’s are off, data is being received from the GPS receiver, but is not at the same BAUD rate
as the GPS receiver. You can set the Baud rate to AUT, and the Smartbar will automatically
match its BAUD rate to that of the GPS receiver. Alternatively, you can select the specific
BAUD rate that matches that of the GPS receiver.
The bottom yellow LED’s will sequence when the BAUD rate selection is AUT and the Smart-
bar is trying to match its BAUD rate with that of the GPS receiver. The bottom yellow LED’s
will stop sequencing when a BAUD rate match is found. The number of yellow LED’s on for
each side indicates teh BAUD rate:
If all center green LED’s are on, but the left red LED’s are not sequencing, you are receiving
messages at the correct BAUD rate, but they are not the correct messages. You need both
$GPGGA and $GPVTG messages, or the single $GPRMC message.
If the left red LED’s are sequencing, then $GPGGA messages are being received. The
$GPGGA message contains position and GPS status information.
If the right red LED’s are sequencing, then $GPVTG messages are being received. The
$GPVTG message contains course and speed information.
If the Smartbar is receiving $GPRMC messages, the left and right LED’s will sequence. The
$GPRMC message contains position, GPS status, course, and speed information.
Note:
The 3 center green LED’s are used to diagnose communication problems (especially
during installation). The top green LED monitors the receive-data signal directly. It will
come on momentarily whenever there is any activity on the receive-data signal. The
middle green LED indicates a properly formatted message has been received. The
bottom green LED indicates multiple properly formatted messages are being received.
The top green LED will flash when the GPS position solution rate is less than 5 hertz.
This is not an error condition. 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.
The default setting is GEN (Generic). When SYS-GPS is set to INV, and MENU
button is pressed, ‘INV-SEL-TO-INI.’ will appear. Pressing the SELECT button will
automatically set up the port of the invicta receiver that the RGL 600 is connected.
Baud rate will be set at 19200, GGA-ON at 10 Hz, VTG-ON at 10 Hz.
