3.7 Connection with GYRO (IEC61162-1/2)
The HDT sentence and THS sentence of IEC-61162-1/2 can be received.
The baud reat conforms to 4800/9600/19200/38400bps.
Connection shoud be made to TB305 (GYRO RX+, GYRO RX-) of standard
terminal board circuit CQD-2121 located in the display unit (processing unit).
The gyro interface circuit should be set at NMEA input. It is necessary to check
specifications of the signal outputted from the heading sensor and make correct settings by
referring to Section.
The true bearing update frequency greatly influences
the radar signal processing performance and the target
tracking performance. It is recommended that the
signal output from the heading sensor be updated
within time intervals of 50 ms or less. The maximum
update time interval recognized by this radar is
approximately 60 ms. If update is executed at an
interval that is longer than that interval, the "GYRO
I/F(GYRO)" alarm is displayed on the radar screen.
The received bearing data is not accepted.
