Nmea Port Connection For Gps Data - KNS Ku-BAND TX Installation And Operation Manual

3.6.3.5 NMEA Port Connection for GPS Data

The GPS is located on the elevation plate of the antenna. The GPS antenna sends
correct GPS data to the PCU when GPS data is available. Then, the PCU sends the GPS
data to the ACU.
However, if GPS data is not available, the GPS antenna does not send GPS data to the
PCU. Also, the GPS antenna will not send GPS data to the PCU if it (GPS) is broken. In
this case, the PCU sends default GPS data value to ACU, which is saved data gathered
from GPS antenna.
The PCU sends the GPS data to the ACU via the receive (RX) L-band cable. The ACU
processes and regenerates the GPS information received from the PCU via the DB-9
NMEA (RS232) and the RJ-45 console port.
The format and baud rate of the GPS can be configured as GPRMC or GPGLL or
GPGGA, and from 1200 to 115200 bps, respectively, using the KA-160 ACU. The DB-9
NMEA and the RJ-45 ports can each have a different format and baud rate. Please refer to
the '7.2.8 GPS Output Format & Baudrate' of installation mode for further details.
NOTE: At the first power-on for the GPS antenna, it will take about 5 minutes to
calculate your location from GPS satellite signals and configure the database
NOTE: If the internal GPS is broken or non-valid, the KA-160 ACU can accept the
external GPS signal. But order of priority is given to the internal GPS signal.
NOTE: If the ship's gyro is a GPS compass that has a heading angle and GPS data,
the KA-160 ACU can accept the heading angle and the GPS signal via the Gyro
connector (DB-15 pins) at the same time.
