Status LEDs
There are 4 LEDs on the front face of the unit
labeled as follows:
•
POWER (red): Unit has power.
•
GPS (yellow): GPS signals have been
acquired and calculated data is being
sent out.
•
DIFF (yellow): SBAS differential satellite available.
•
DGPS (green): Differential corrections are active, resulting in
improved data. This is the light you really want to see on.
There are only two required lights for operation, one is POWER and the
other GPS. The DIFF and DGPS lights indicate increased accuracy of
the data. With differential correction, you will get the most accurate
data. Therefore best operation is achieved with these lights on.
20 Hz Update Option
This option allows the following four channels to update at a true
20 Hz rate:
•
GPS Latitude
•
GPS Longitude
•
GPS Speed
•
GPS Heading
It’s best to buy this option at the time of purchase. If you buy it
afterwards, the unit must be sent to MoTeC for updating.
RS-232 Serial Output
Standard NMEA-0183 message strings GPGGA and GPRMC are
sent out by default at a baud rate of 57,600. The baud rate and type of
messages can be changed by sending the unit back to MoTeC.
